Productivity utils for flutter/plugins and flutter/packages

Flutter Plugin Tools

This is a set of utilities used in the flutter/plugins and flutter/packages repositories. It is no longer explictily maintained as a general-purpose tool for multi-package repositories, so your mileage may vary if using it in other repositories.

Note: The commands in tools are designed to run at the root of the repository or <repository-root>/packages/.

Getting Started

In flutter/packages, the tool is run from source. In flutter/plugins, the published version is used instead.

The commands in tools require the Flutter-bundled version of Dart to be the first dart loaded in the path.

Extra Setup

When updating sample code excerpts (update-excerpts) for the README.md files, there is some extra setup for submodules that is necessary.

From Source (flutter/packages only)

Set up:

cd ./script/tool && dart pub get && cd ../../

Run:

dart run ./script/tool/bin/flutter_plugin_tools.dart <args>

Published Version

Set up:

dart pub global activate flutter_plugin_tools

Run:

dart pub global run flutter_plugin_tools <args>

Commands

Run with --help for a full list of commands and arguments, but the following shows a number of common commands being run for a specific package.

All examples assume running from source; see above for running the published version instead.

Most commands take a --packages argument to control which package(s) the command is targetting. An package name can be any of:

• The name of a package (e.g., path_provider_android).
• The name of a federated plugin (e.g., path_provider), in which case all packages that make up that plugin will be targetted.
• A combination federated_plugin_name/package_name (e.g., path_provider/path_provider for the app-facing package).

Format Code

cd <repository root>
dart run ./script/tool/bin/flutter_plugin_tools.dart format --packages package_name

Run the Dart Static Analyzer

cd <repository root>
dart run ./script/tool/bin/flutter_plugin_tools.dart analyze --packages package_name

Run Dart Unit Tests

cd <repository root>
dart run ./script/tool/bin/flutter_plugin_tools.dart test --packages package_name

Run Dart Integration Tests

cd <repository root>
dart run ./script/tool/bin/flutter_plugin_tools.dart build-examples --apk --packages package_name
dart run ./script/tool/bin/flutter_plugin_tools.dart drive-examples --android --packages package_name

Replace --apk/--android with the platform you want to test against (omit it to get a list of valid options).

Run Native Tests

native-test takes one or more platform flags to run tests for. By default it runs both unit tests and (on platforms that support it) integration tests, but --no-unit or --no-integration can be used to run just one type.

Examples:

cd <repository root>
# Run just unit tests for iOS and Android:
dart run ./script/tool/bin/flutter_plugin_tools.dart native-test --ios --android --no-integration --packages package_name
# Run all tests for macOS:
dart run ./script/tool/bin/flutter_plugin_tools.dart native-test --macos --packages package_name
# Run all tests for Windows:
dart run ./script/tool/bin/flutter_plugin_tools.dart native-test --windows --packages package_name

Update README.md from Example Sources

update-excerpts requires sources that are in a submodule. If you didn't clone with submodules, you will need to git submodule update --init --recursive before running this command.

cd <repository root>
dart run ./script/tool/bin/flutter_plugin_tools.dart update-excerpts --packages package_name

Update CHANGELOG and Version

update-release-info will automatically update the version and CHANGELOG.md following standard repository style and practice. It can be used for single-package updates to handle the details of getting the CHANGELOG.md format correct, but is especially useful for bulk updates across multiple packages.

For instance, if you add a new analysis option that requires production code changes across many packages:

cd <repository root>
dart run ./script/tool/bin/flutter_plugin_tools.dart update-release-info \
  --version=minimal \
  --changelog="Fixes violations of new analysis option some_new_option."

The minimal option for --version will skip unchanged packages, and treat each changed package as either bugfix or next depending on the files that have changed in that package, so it is often the best choice for a bulk change.

For cases where you know the change time, minor or bugfix will make the corresponding version bump, or next will update only CHANGELOG.md without changing the version.

Publish a Release

Releases are automated for flutter/plugins and flutter/packages.

The manual procedure described here is deprecated, and should only be used when the automated process fails. Please, read Releasing a Plugin or Package on the Flutter Wiki first.

cd <path_to_repo>
git checkout <commit_hash_to_publish>
dart run ./script/tool/bin/flutter_plugin_tools.dart publish --packages <package>

By default the tool tries to push tags to the upstream remote, but some additional settings can be configured. Run dart run ./script/tool/bin/flutter_plugin_tools.dart publish --help for more usage information.

The tool wraps pub publish for pushing the package to pub, and then will automatically use git to try to create and push tags. It has some additional safety checking around pub publish too. By default pub publish publishes everything, including untracked or uncommitted files in version control. publish will first check the status of the local directory and refuse to publish if there are any mismatched files with version control present.

Updating the Tool

For flutter/packages, just changing the source here is all that's needed.

For changes that are relevant to flutter/packages, you will also need to:

• Update the tool's pubspec.yaml and CHANGELOG
• Publish the tool
• Update the pinned version in flutter/packages
