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.

  • Package is pre-release.

    Pre-release versions should be used with caution, their API may change in breaking ways.

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Maintain an example.

    None of the files in your example/ directory matches a known example patterns. Common file name patterns include: main.dart, example.dart or you could also use front_end.dart.
