d_rocket_builder 1.0.6

`build_runner` codegen for the `d_rocket` framework: generates `@Serializable`, `@RestClient`, `@Table` handlers and the central `initializeD()` registry.

🔨 d_rocket_builder

Codegen for the d_rocket framework.

This is the build-time companion to d_rocket. It runs under build_runner and emits all the wiring you don't want to write by hand:

Builder	What it emits
d_rocket:rocket_serializer	Per-class fromJson / toJson and central register<X>Serializer calls.
d_rocket:rocket_rest_client	Per-interface RestClient implementations with interceptors, retry, and serialization wired in.
d_rocket:rocket_table	Per-class fromRow (row materialiser) and setId (back-propagation hook) closures for the ORM.
d_rocket:rocket_closure (optional)	Closure-sugar where / select / orderBy extensions for prototyping over Iterable<T>.
d_rocket:rocket_migration (CLI)	dart run d_rocket:rocket_migration add <name> scaffolder.

The codegen is the reason the runtime can offer a single initializeD() call: every annotation in the project is collected into a central d_rocket_registry.g.dart that registers serializers, REST clients, and ORM metadata at startup.

Installation

Add the builder as a dev dependency (it must NOT be in your main dependencies — it never ships with the app):

dev_dependencies:
  d_rocket: ^1.0.0
  d_rocket_builder: ^1.0.0
  build_runner: ^2.4.13

Then fetch and run the generator:

dart pub get
dart run build_runner build --delete-conflicting-outputs

The first run creates d_rocket_registry.g.dart and a *.d_rocket_*.g.dart file next to every annotated source file. Re-run the generator after every schema or API change.

Quickstart

A minimal pubspec.yaml snippet for a project that uses serialization, REST, and the ORM:

name: my_app
description: My first d_rocket app
publish_to: none

environment:
  sdk: ^3.5.0
  flutter: ">=3.10.0"

dependencies:
  d_rocket: ^1.0.0

dev_dependencies:
  d_rocket_builder: ^1.0.0
  build_runner: ^2.4.13

Annotate your models:

@Serializable()
class Customer {
  Customer({required this.id, required this.name, required this.email});
  final int id;
  final String name;
  final String email;
}

@RestClient(baseUrl: 'https://api.example.com')
abstract class ShopClient {
  @HttpGet('/customers/{id}')
  Future<Customer> getCustomer(@Path('id') int id);
}

@RocketTable('customers')
class CustomerEntity {
  @PrimaryKey(autoIncrement: true) final int id;
  @Column() final String name;
  @Column() final String email;
}

Run the generator:

$ dart run build_runner build
[INFO] Generating build script completed in 0.3s
[INFO] Running build...
[INFO] Succeeded after 1.2s with 7 outputs (24 actions)

A new file lib/d_rocket_registry.g.dart now contains your initializeD() function. Call it in main():

import 'package:my_app/d_rocket_registry.g.dart';

void main() {
  initializeD();
  // every @Serializable, @RestClient, and @RocketTable
  // in the project is now wired up.
  runApp(const MyApp());
}

What gets generated

For a class Foo annotated with @Serializable():

• Foo.fromJson(Map<String, Object?> json) — named factory.
• Map<String, Object?> toJson() on Foo.
• registerFooSerializer() call in d_rocket_registry.g.dart.

For an interface IBar annotated with @RestClient:

• _BarClient implements IBar (private to the generated file).
• Per-method implementation that builds the HTTP request, runs the interceptor chain, applies retry / rate-limit / circuit-breaker, decodes the response, and deserializes through the registered serializer.

For a class Baz annotated with @RocketTable:

• Baz.fromRow(Map<String, Object?> row) — row materialiser.
• void setId(Baz baz, Object id) — back-propagation hook for the DB-assigned primary key.
• BazSchema constants (table name, column names) consumed by the SQL provider.

For a class Qux annotated with @WebSocketRoute / @SseRoute:

• Stream<Qux> ...() method bodies in a generated _QuxWsClient / _QuxSseClient.

Lint rules

d_rocket_builder ships two custom lint rules under package:custom_lint_builder:

• d_rocket_n_plus_one — flags LINQ queries that trigger N+1 round-trips. Promotes include_<T>() and pre-fetch.
• d_rocket_closure — flags LINQ operators used on raw Iterable<T> without an Expr (these evaluate in-memory only and can't be pushed to SQL).

Enable them in your analysis_options.yaml:

analyzer:
  plugins:
    - custom_lint

linter:
  rules:
    - d_rocket_n_plus_one
    - d_rocket_closure

CLI tools

Two CLIs are exposed as executables on the d_rocket_builder package:

# Scaffold a new migration with the right id, class name,
# and pre-filled up() / down() bodies.
dart run d_rocket:rocket_migration add create_inventory_table
# ✓ Created lib/db/migrations/M005_create_inventory_table.dart
#   id: 005, class: M005CreateInventoryTable

# Validate that the migration history is contiguous (no gaps).
dart run d_rocket:rocket_migration doctor
# ✓ Migration history is contiguous (5 migrations).
