When mixin is applied, its instance members are cloned and copies
of the members would override original members.
This change fixes bugs and improved usability of extendable mixins with
private members:
- All instance members of extendable mixins and mixin classes are
marked as can-be-overridden to allow overriding by cloned members
when mixin is applied.
- TFA no longer takes privacy into account, as private members of
mixins can be overridden by their clones in other libraries.
- Dynamic module validator always unwraps cloned members to originals
before verifying if overriding is allowed. This eliminates overriding
errors between clone(s) and original members of mixins.

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 dart analyze
command-line tool to analyze their Dart code.
Integrators that want to write tools that analyze Dart code should use the analyzer package.
Note: A previous version of this package was published on pub.dev. It has now been marked DISCONTINUED as it is not intended for direct consumption, as per the notes above.
