clean_architect

A configurable Dart CLI generator for Clean Architecture Flutter/Dart projects.

clean_architect generates boring, predictable architecture files that you can edit immediately. The generator does not try to hide your app behind runtime abstractions. The flexibility lives in clean_architect.yaml: paths, layer layout, state management, network client, local storage, model style, and dependency injection style.

Install

dart pub global activate clean_architect

After global activation you can run the executable from any folder:

clean_architect init
clean_architect create architecture
clean_architect create auth
clean_architect create feature orders

Empty Folder Usage

Use the global executable when generating into an empty folder:

mkdir my_app
cd my_app
clean_architect create architecture

Do not use dart run clean_architect ... in an empty folder. dart run needs a local pubspec.yaml before the CLI can start. Use dart run clean_architect ... only when developing this package from its own checkout or from another Dart project that already has a pubspec.yaml.

Commands

clean_architect --version
clean_architect <command> --help
clean_architect create feature --help
clean_architect init
clean_architect doctor
clean_architect create architecture
clean_architect create base
clean_architect create auth
clean_architect create feature <name>
clean_architect create usecase <name> --feature <feature>
clean_architect create repository <feature>
clean_architect create remote-function <name> --feature <feature>
clean_architect create local-function <name> --feature <feature>
clean_architect create cached-function <name> --feature <feature>

Examples:

clean_architect init
clean_architect create architecture
clean_architect create feature orders
clean_architect create auth
clean_architect create usecase login --feature auth
clean_architect create repository auth
clean_architect create remote-function loadDetails --feature orders
clean_architect create local-function readDraft --feature orders
clean_architect create cached-function syncDetails --feature orders
clean_architect doctor

Useful flags:

clean_architect init --dry-run
clean_architect init --force

clean_architect create architecture --dry-run
clean_architect create auth --dry-run
clean_architect create auth --overwrite
clean_architect create auth --force
clean_architect create feature profile --skip-presentation

clean_architect create auth --state getx
clean_architect create auth --state bloc
clean_architect create auth --state provider
clean_architect create auth --state none
clean_architect create auth --network dio
clean_architect create auth --network abstract
clean_architect create auth --storage secure_storage
clean_architect create auth --storage shared_preferences
clean_architect create auth --storage hive
clean_architect create auth --storage objectbox
clean_architect create auth --storage abstract
clean_architect create auth --di injectable
clean_architect create auth --dependency-injection manual
clean_architect create feature orders --use-either-failure
clean_architect create feature orders --no-use-either-failure
clean_architect create architecture --flutter-create --platforms android,ios
clean_architect create auth --flutter-create --platforms android,ios,web

--overwrite and --force are required before conflicting generated files are replaced. Complete features and identical generated files are treated as idempotent no-ops.

CLI overrides are intentionally small and only affect the current command. They do not rewrite clean_architect.yaml.

Generated Project Shape

The default layered_packages architecture is a multi-package Flutter/Dart workspace shape:

my_app/
  domain/
    pubspec.yaml
    lib/
      features/
        base_feature/
          entities/
          repositories/
          usecases/

  data/
    pubspec.yaml
    lib/
      features/
        base_feature/
          remote/
            models/
          local/
            models/
          repositories/

  di/
    pubspec.yaml
    lib/

  presentation/
    pubspec.yaml
    analysis_options.yaml
    asset_generator_kit.yaml
    assets/
      images/
      icons/
    lib/
      main.dart
      widgets/
      pages/
      utils/
      controllers/
      constants/

Every layer gets its own pubspec.yaml:

domain is a pure Dart package for entities, repository contracts, and use cases.
data is a Dart/Flutter package for DTOs, remote data sources, local sources, mappers, and repository implementations.
di is a Dart package that connects domain and data dependencies.
presentation is a runnable Flutter package with main.dart, Flutter dependencies, and UI folders.

After generation, run Flutter setup inside presentation when you want a complete Flutter platform project:

cd presentation
flutter create .
flutter pub get

Or let clean_architect do the Flutter project bootstrap automatically:

clean_architect create architecture --flutter-create --platforms android,ios

The same behavior can be configured in clean_architect.yaml:

clean_architect:
  flutter:
    create_presentation: true
    platforms:
      - android
      - ios
      - web

When enabled, the CLI runs flutter create . --platforms=<platforms> from the generated presentation/ package root, or from app/ in vertical_packages mode. --dry-run prints the command without executing it. --skip-presentation disables this step for the current command.

Run dart pub get in the other layer packages as needed.

Data Layer Layouts

data_layout changes only the internal organization of each feature's data layer. Domain, presentation, DI, package roots, class names, and command behavior remain unchanged.

The default source_first mode keeps each model beside its source category:

clean_architect:
  data_layout: source_first

data/lib/features/orders/
  remote/
    models/
      orders_dto.dart
    orders_remote_data_source.dart
  local/
    models/
      orders_box.dart
    orders_local_data_source.dart
  mappers/
  repositories/

Use type_first to keep models and data sources in separate top-level directories:

clean_architect:
  data_layout: type_first

data/lib/features/orders/
  data_sources/
    remote/
      orders_remote_data_source.dart
    local/
      orders_local_data_source.dart
  models/
    remote/
      orders_dto.dart
    local/
      orders_box.dart
  mappers/
  repositories/

The setting applies to create architecture, create auth, create feature, all remote/local/cached operation commands, and generated Injectable DataModule imports. It also works inside each feature package when structure: vertical_packages is selected. Existing configurations that omit the key continue to generate source_first.

Generated Output Contract

These manifests are generated from the public Dart API and checked against this README in the test suite. They are the authoritative file output for the default configuration; narrative examples elsewhere describe selected files only.

Flutter Presentation Bootstrap

By default, clean_architect creates the presentation package files but does not run Flutter tooling. This keeps generation fast and works even on machines without Flutter installed.

To generate Flutter platform folders automatically, use:

clean_architect create architecture --flutter-create --platforms android,ios

Supported platform names are the Flutter platform names: android, ios, web, macos, windows, and linux.

The YAML equivalent is:

clean_architect:
  flutter:
    create_presentation: true
    platforms: android,ios

or:

clean_architect:
  flutter:
    create_presentation: true
    platforms:
      - android
      - ios

This runs for commands that generate presentation structure: create architecture, create base, create auth, and create feature <name>. It is skipped for operation commands, create usecase, create repository, and commands using --skip-presentation. In vertical_packages, Flutter scaffolding is created in the configured app package.

Structure Modes

Default Layered Packages

clean_architect:
  config_version: 1
  structure: layered_packages
  paths:
    domain: domain/lib
    data: data/lib/features
    presentation: presentation/lib
    di: di/lib

clean_architect create auth creates:

domain/lib/features/auth/...
data/lib/features/auth/...
di/lib/auth_di.dart
di/lib/di.dart
presentation/lib/controllers/auth_controller.dart
presentation/lib/pages/login_page.dart

Custom Layer Paths

You can point the layers to existing packages or app folders:

clean_architect:
  config_version: 1
  structure: layered_packages
  paths:
    domain: packages/domain/lib/modules
    data: packages/data/lib/modules
    presentation: apps/customer_app/lib
    di: packages/di/lib

Then clean_architect create feature profile creates feature files under those configured roots.

Feature First

feature_first is available for projects that still want feature-based grouping while keeping the same layer packages:

clean_architect:
  config_version: 1
  structure: feature_first
  paths:
    domain: domain/lib
    data: data/lib/features
    presentation: presentation/lib
    di: di/lib

Feature-first resolution keeps the four layer packages while grouping each feature inside every layer:

domain/lib/features/<feature>/...
data/lib/features/<feature>/...
presentation/lib/features/<feature>/pages/...
presentation/lib/features/<feature>/controllers/...
di/lib/features/<feature>/...

Vertical Feature Packages

Use vertical_packages when features should be independent packages that own all of their architecture layers:

clean_architect:
  config_version: 1
  structure: vertical_packages
  state_management: bloc
  network: dio
  local_storage: hive
  dependency_injection: injectable
  use_asset_generator: false
  use_either_failure: true
  flutter:
    create_presentation: true
    platforms: [android, ios, web]
  models:
    use_freezed: true
    use_json_serializable: true
  paths:
    app: app/lib
    core: packages/core/lib
    features: packages/features

Then run:

clean_architect create architecture
clean_architect create auth
clean_architect create feature orders

The result is a runnable app shell, a stable shared core, and one package per feature:

app/
  pubspec.yaml
  assets/
    icons/
    images/
  lib/
    main.dart
    app.dart
    constants/
    controllers/
    di/
    pages/
    routing/
    theme/
    utils/
    widgets/
  test/

packages/
  core/
    pubspec.yaml
    lib/
      core.dart
      src/
        errors/
        failures/
        logging/
        usecases/

  features/
    auth/
      pubspec.yaml
      lib/
        auth.dart
        src/
          domain/
            entities/
            repositories/
            usecases/
          data/
            remote/
              models/
            local/
              models/
            mappers/
            repositories/
          presentation/
            controllers/
            pages/
          di/

Every feature package has one pubspec.yaml, so its domain, data, presentation, and DI code evolve together without cross-feature imports. The app manifest is updated with an idempotent path dependency whenever auth, a generic feature, or a standalone repository package is created. Injectable configuration and Hive/ObjectBox providers live in each feature's lib/src/di/ folder.

Each package also gets a public barrel, such as orders/lib/orders.dart, which exports its stable entities, repository contract, use cases, page, controller, and DI entry point. Consumers import only the package API:

import 'package:orders/orders.dart';

Operation commands extend this barrel when they add new entities and use cases.

The generated ARCHITECTURE.md records these dependency rules:

The app may depend on core and feature packages.
A feature owns its domain, data, presentation, and DI code.
Features may depend on core but must not import one another.
Core must not depend on the app or any feature.

With Flutter creation enabled, the project is immediately runnable:

cd app
flutter pub get
flutter run

`create architecture`

clean_architect create architecture

Generates the layer packages and default folders only. It does not generate auth code.

Default placeholder feature name:

domain/lib/features/base_feature
data/lib/features/base_feature

Use this when you want the clean architecture project skeleton first, then add features later.

`create feature <name>`

clean_architect create feature orders

Generates a generic feature module.

Domain:

domain/lib/features/orders/entities/orders_entity.dart
domain/lib/features/orders/repositories/orders_repository.dart
domain/lib/features/orders/usecases/get_orders_list_use_case.dart

Data:

data/lib/features/orders/remote/models/orders_dto.dart
data/lib/features/orders/remote/orders_remote_data_source.dart
data/lib/features/orders/local/models/orders_box.dart
data/lib/features/orders/local/orders_local_data_source.dart
data/lib/features/orders/mappers/orders_mapper.dart
data/lib/features/orders/repositories/orders_repository_impl.dart

Presentation, unless --skip-presentation is used:

presentation/lib/controllers/orders_controller.dart
presentation/lib/pages/orders_page.dart

The generic feature is intentionally minimal: entity, DTO, mapper, repository contract, repository implementation, list use case, local source, Retrofit remote data source, controller, and page. Its OrdersViewItem is a real widget declared in orders_page.dart, so a one-off UI element does not get its own file.

`create auth`

clean_architect create auth

Generates a concrete auth starter feature.

Domain:

domain/lib/features/auth/entities/auth_token_entity.dart
domain/lib/features/auth/entities/auth_credentials_entity.dart
domain/lib/features/auth/repositories/auth_repository.dart
domain/lib/features/auth/usecases/login_use_case.dart
domain/lib/features/auth/usecases/logout_use_case.dart
domain/lib/features/auth/usecases/save_auth_credentials_use_case.dart
domain/lib/features/auth/usecases/get_auth_credentials_use_case.dart
domain/lib/features/auth/usecases/clear_auth_credentials_use_case.dart

Data:

data/lib/features/auth/remote/models/auth_token_dto.dart
data/lib/features/auth/remote/models/login_request_dto.dart
data/lib/features/auth/remote/auth_remote_data_source.dart
data/lib/features/auth/local/models/auth_box.dart
data/lib/features/auth/local/auth_local_data_source.dart
data/lib/features/auth/mappers/auth_token_mapper.dart
data/lib/features/auth/repositories/auth_repository_impl.dart

Presentation, unless --skip-presentation is used:

presentation/lib/controllers/auth_controller.dart
presentation/lib/pages/login_page.dart

Login form data is generated as LoginState in auth_controller.dart; it is not emitted as a non-widget file under widgets/.

The generated remote remote data source uses Dio + Retrofit style:

@lazySingleton
@RestApi(baseUrl: '')
abstract class AuthRemoteDataSource {
  @factoryMethod
  factory AuthRemoteDataSource(@Named("auth_dio") Dio dio) = _AuthRemoteDataSource;

  @POST('/authorization/token/')
  Future<AuthTokenDto> login(@Body() Map<String, dynamic> body);
}

The generated auth controller uses GetIt.instance.get<LoginUseCase>(), and the GetX page registers the controller in initState with Get.put(AuthController()).

Operation Commands

Operation commands add a new function to an existing feature. They generate the required entity/model/usecase support files and patch the existing source, repository, repository implementation, and controller files.

Remote Function

clean_architect create remote-function loadDetails --feature orders

Aliases: remote-function, remote-method.

Adds:

domain/lib/features/orders/entities/load_details_entity.dart
domain/lib/features/orders/usecases/load_details_use_case.dart
data/lib/features/orders/remote/models/load_details_dto.dart
data/lib/features/orders/mappers/load_details_mapper.dart

Patches:

data/lib/features/orders/remote/orders_remote_data_source.dart
domain/lib/features/orders/repositories/orders_repository.dart
data/lib/features/orders/repositories/orders_repository_impl.dart
presentation/lib/controllers/orders_controller.dart

Local Function

clean_architect create local-function readDraft --feature orders

Aliases: local-function, local-method.

Adds:

domain/lib/features/orders/entities/read_draft_entity.dart
domain/lib/features/orders/usecases/read_draft_use_case.dart
data/lib/features/orders/local/models/read_draft_box.dart
data/lib/features/orders/mappers/read_draft_mapper.dart

Patches the local source, repository contract, repository implementation, and controller.

Cached Function

clean_architect create cached-function syncDetails --feature orders

Aliases: cached-function, cached-method.

Adds remote and local support together:

domain/lib/features/orders/entities/sync_details_entity.dart
domain/lib/features/orders/usecases/sync_details_use_case.dart
domain/lib/features/orders/usecases/stream_details_use_case.dart
data/lib/features/orders/remote/models/sync_details_dto.dart
data/lib/features/orders/local/models/sync_details_box.dart
data/lib/features/orders/mappers/sync_details_mapper.dart
data/lib/features/orders/mappers/sync_details_box_mapper.dart

Patches the remote source with syncDetails(), the local source with streamDetails(), and uses those same names in the repository, use cases, repository implementation, and controller. The generated use cases are SyncDetailsUseCase and StreamDetailsUseCase.

Dependency Injection Modes

Manual

dependency_injection: manual

Manual mode generates a single GetIt bootstrap plus editable per-feature registration files:

di/lib/di.dart
di/lib/auth_di.dart
di/lib/orders_di.dart

initDi initializes every feature's data dependencies first and domain use cases second. Local storage is awaited before remote sources and repositories are registered. Generated registrations use isRegistered guards, so startup and generator reruns remain idempotent. Presentation calls the bootstrap before runApp:

WidgetsFlutterBinding.ensureInitialized();
await initDi(get: GetIt.instance);
runApp(const CleanArchitectApp());

Creating another feature patches the root bootstrap. Creating a use case or an operation patches that feature's domain registrations. In vertical_packages, the equivalent bootstrap lives at app/lib/di/bootstrap.dart and each feature exports its registration functions from its public library.

Injectable

dependency_injection: injectable

Injectable mode adds injectable/get_it dependencies and generates injector entry files:

domain/lib/injector.dart
data/lib/injector.dart
di/lib/di.dart

Generated classes receive injectable annotations where supported. After generation, run build runner in the generated packages that contain injectable/freezed/json_serializable code.

cd domain
dart run build_runner build
cd ../data
dart run build_runner build

In vertical_packages, each feature has one injector and data module:

packages/features/orders/lib/src/di/injector.dart
packages/features/orders/lib/src/di/data_module.dart

Run build runner from that feature package:

cd packages/features/orders
dart run build_runner build --delete-conflicting-outputs

Either / Failure Return Type

use_either_failure: true

When enabled, generated repository contracts, repository implementations, and use cases use:

Future<Either<Failure, T>>

instead of:

Future<T>

The generator also creates domain/lib/failures/failure.dart where needed and adds dartz to generated layer pubspecs. Vertical features reuse the shared Failure from packages/core. You can override the value for one command with --use-either-failure or --no-use-either-failure.

Model Modes

Freezed + JSON Serializable

models:
  use_freezed: true
  use_json_serializable: true

Entities and DTOs use Freezed. DTOs also include JSON serialization parts when JSON serialization is enabled.

Typical follow-up command in generated packages:

dart run build_runner build

Plain Dart Fallback

models:
  use_freezed: false
  use_json_serializable: false

Entities and DTOs are generated as simple Dart classes.

State Management

GetX

state_management: getx

Presentation controllers extend GetxController, pages use Get.put(...), Get.find(...), and reactive values where needed.

Bloc

state_management: bloc

Presentation controllers use flutter_bloc with event/state classes, and pages use BlocProvider/BlocBuilder.

Provider

state_management: provider

Presentation controllers extend ChangeNotifier, and pages use ChangeNotifierProvider/Consumer.

None

state_management: none

Presentation files are generated without state management package wiring. This is useful when you want to connect another state system manually.

Network

Dio

network: dio

Generated remote services use Dio + Retrofit imports and annotations. The data package receives the relevant dependencies.

Abstract

network: abstract

Use this when you want the generated repositories and source boundaries but plan to implement networking yourself.

Local Storage

Secure Storage

local_storage: secure_storage

Auth local source uses flutter_secure_storage for credential persistence.

Hive

local_storage: hive

The data package uses the maintained Hive CE runtime and generator packages. Local sources can initialize their boxes directly. Injectable projects get a generated module that initializes Hive, registers each adapter with a stable type ID, opens each box, and provides the box to its local data source:

data/lib/data_module.dart

Adding another Hive feature or local/cached operation updates the same module with the additional adapter and box provider.

Generated local models keep an integer id for the Hive/ObjectBox database key and a String remoteId for the API identity. DTO id values map to Entity.remoteId and Box.remoteId, so remote identifiers never overwrite local database keys.

ObjectBox

local_storage: objectbox

The data package gets ObjectBox dependencies, local sources can initialize their box from a Store, and injectable projects get a generated module:

data/lib/data_module.dart

Run build runner in the data package after adding ObjectBox entities so objectbox.g.dart can be generated.

Abstract

local_storage: abstract

Auth local source contains TODO methods so you can wire a custom persistence mechanism yourself.

Dependency Compatibility

Version 0.3.0 emits only the dependencies required by the selected configuration. Runtime packages use their current stable releases. Builder packages use the newest mutually compatible stable set verified against generated Flutter projects:

build_runner: ^2.15.1
freezed: ^3.2.5
injectable_generator: ^3.0.2
hive_ce_generator: 1.11.1

Some newer individual builder releases target incompatible analyzer versions. These constraints avoid prerelease transitive dependencies while allowing Freezed, Retrofit, Injectable, and Hive CE generation to run together.

Presentation Package

The generated presentation package includes:

presentation/lib/main.dart
presentation/lib/widgets/
presentation/lib/pages/
presentation/lib/utils/
presentation/lib/controllers/
presentation/lib/constants/
presentation/assets/images/
presentation/assets/icons/

When use_asset_generator: true, it also includes:

presentation/asset_generator_kit.yaml

and adds assetgeneratorkit to presentation/pubspec.yaml.

Safety

Every generation command builds a complete in-memory plan first. Names, configuration, required features, duplicate outputs, and filesystem conflicts are validated before the first file is written. If any conflict is found, the command aborts without partially generating the remaining files.

Identical files are left untouched, and rerunning a completed feature or operation is an idempotent no-op. Operation commands require the feature to already exist:

clean_architect create feature orders
clean_architect create cached-function syncCatalog --feature orders

By default, conflicting existing files are not overwritten.

Preview generated files:

clean_architect create auth --dry-run

Overwrite intentionally:

clean_architect create auth --overwrite

or:

clean_architect create auth --force

Doctor

clean_architect doctor

doctor validates the complete generated project:

Every configured package root and layer path exists and is structurally valid.
Each layer has a readable pubspec.yaml whose package name matches its root.
Required dependencies and dev dependencies are present with compatible version constraints.
Local path dependencies resolve to the configured domain, data, and DI packages.
The active Dart and Flutter versions satisfy the generated package constraints.
build_runner is declared and resolved in every package that needs it.
Every referenced generated .g.dart file exists.
Vertical app, core, and every discovered feature package are checked.

A healthy project exits with code 0. Failed validation exits with code 1, so clean_architect doctor can be used directly in CI.

Integration Test Matrix

The integration suite generates complete projects in temporary directories, then runs dependency resolution, code generation, analysis in every layer, and the project doctor.

Scenario	Coverage
`default_getx_manual_dio_secure`	Layered packages, GetX, manual DI, Dio, secure storage
`bloc_injectable_hive_feature_first`	Feature first, Bloc, Injectable, Hive CE
`provider_injectable_objectbox`	Layered packages, type-first data layout, Provider, Injectable, ObjectBox
`getx_manual_objectbox`	Layered packages, type-first data layout, GetX, manual GetIt registration, ObjectBox
`none_abstract_plain_feature_first`	Feature first, no state package, abstract sources, plain Dart models
`either_enabled`	Layered packages with `Either<Failure, T>` returns
`shared_preferences_json_only_custom_paths`	Shared preferences, JSON-only models, and custom public layer paths
`freezed_without_json`	Freezed-only models, Injectable, and manual JSON methods
`vertical_bloc_injectable_hive_either`	Vertical feature packages, type-first data layout, runnable app/core packages, Bloc, Injectable, Hive CE, and Either

Normal dart test runs skip these expensive cases. Run the full matrix with:

CLEAN_ARCHITECT_INTEGRATION=all dart test test/integration/generated_project_matrix_test.dart

Run one scenario while developing:

CLEAN_ARCHITECT_INTEGRATION=provider_injectable_objectbox dart test test/integration/generated_project_matrix_test.dart

Keep generated projects after success for manual inspection:

CLEAN_ARCHITECT_INTEGRATION=all CLEAN_ARCHITECT_KEEP_INTEGRATION_PROJECTS=true dart test test/integration/generated_project_matrix_test.dart

Every scenario creates the architecture, auth, an orders feature, standalone use case and repository files, and all three operation types. It reruns every generation command without allowing any file changes, then resolves dependencies, runs builders and analysis, and requires clean_architect doctor to pass. GitHub Actions runs each scenario as a separate matrix job. The vertical scenario also generates a real Flutter web scaffold, runs its widget tests, and builds the app.

1.0 Stability Contract

Version 1.0.0 establishes the stable interface. Existing commands, options, configuration keys, generated package roots, and exported Dart APIs follow the compatibility and deprecation policy below.

Frozen CLI surface

Command	Status
`init`	Supported
`doctor`	Supported
`create architecture`	Supported
`create auth`	Supported
`create feature <name>`	Supported
`create usecase <name> --feature <feature>`	Supported
`create repository <feature>`	Supported
`create remote-function <name> --feature <feature>`	Supported
`create local-function <name> --feature <feature>`	Supported
`create cached-function <name> --feature <feature>`	Supported

create base, remote-method, local-method, cached-method, and --di remain supported compatibility aliases. Canonical names are used in new documentation and examples.

Frozen public Dart API

Import supported APIs from:

import 'package:clean_architect/clean_architect.dart';

The 1.0 public surface includes the configuration enums and value objects, CleanArchitectGenerator, GeneratedFile, OperationKind, PathResolver, FeaturePaths, ProjectDoctor, its diagnostic/report types, currentConfigVersion, and packageVersion. Files below lib/src are implementation details and are not covered by compatibility guarantees.

Backward compatibility and upgrades

Patch releases fix defects without intentionally changing generated output.
Minor releases may add commands, options, configuration keys, templates, or public APIs. Existing valid configuration remains valid.
A command, key, alias, or public API must be deprecated for at least one minor release before removal.
Breaking changes are reserved for a new major version after 1.0.
Generated source is owned by the consuming project. Upgrading the CLI never rewrites existing files unless the user explicitly passes --force or --overwrite.
config_version controls schema migrations independently from the package version. New optional keys retain defaults; incompatible schema changes increment config_version and include migration instructions.
Golden snapshots protect representative generated output. Intentional template changes must update the corresponding goldens and changelog.

Before upgrading, commit the consuming project, update clean_architect, run clean_architect doctor, preview generation with --dry-run, and review any intentional snapshot-level output changes described in the changelog.

Runnable Example

example/ is a checked-in generated project with domain, data, di, and a Flutter presentation package. It can be launched with:

cd example/presentation
flutter pub get
flutter run -d chrome

CI resolves and analyzes this example and builds its web target on every change.
