forked from mirrors/material_3_expressive
62ecb86b76
- Introduced `.gitignore` and `.metadata` for apps and examples. - Added Flutter/Dart analysis configurations (`analysis_options.yaml`). - Implemented foundational tokens and themes for M3E (colors, shapes). - Created base implementations for `IconButtonM3E` and `SplitButtonM3E`. - Set up CI workflow (`ci.yaml`) to automate testing and analysis.
