dart_board
An extensible flutter-framework
Dart Board allows you to break your app into features and then integration cleanly and consistently. It's essentially a feature loader offering no features but the ability to load and integrate features.
Demo above shows multiple integrated features and switching of templates/themes etc. However the features themselves are not dart-board, just the framework that manages and integrates them is.
For more info see:
Example/Integration documentation
or play with the sample at dart-board.io
Why 0.9.x for now
I think the API and basic features are complete for a 1.0 release.
However, until test coverage it won't be marked 1.x. Use at your own risk.
Tests will come soon, or feel free to contribute.
