This package requires style_generator to be a dependency to build code. Docs and Examples can be found there.

Getting started

dart pub add style_generator_annotation 
dart pub add dev:style_generator 
dart pub add dev:build_runner

or the same in one line:

dart pub add style_generator_annotation dev:style_generator dev:build_runner

For even easier generation, use the Style Generator Templates for Flutter Plugin for Android Studio

Annotations
