Front end for Dart #

This package provides a low-level API for use by compiler back ends that wish to implement the Dart language. It is intended for eventual use by dev_compiler, dart2js, and the Dart VM. In addition, it will share implementation details with the analyzer package--this will be accomplished by having the analyzer package import (and re-export) parts of this package's private implementation.

End-users should use the [dartanalyzer][analyzercli] command-line tool to analyze their Dart code.

Integrators that want to write tools that analyze Dart code should use the [analyzer] package.

Note: The APIs in this package are in an early state; developers should be careful about depending on this package. In particular, there is no semver contract for release versions of this package. Please depend directly on individual versions.

Maintenance issues and suggestions

Fix platform conflicts. (-20 points)

Low code quality prevents platform classification.

Provide a file named CHANGELOG.md. (-20 points)

Changelog entries help developers follow the progress of your package. See the example generated by stagehand.

The package description is too short. (-20 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Maintain an example. (-10 points)

Create a short demo in the example/ directory to show how to use this package.

Common filename patterns include main.dart, example.dart, and front_end.dart. Packages with multiple examples should provide example/README.md.

For more information see the pub package layout conventions.
