Contributed to the flutter/flutter repository by enhancing API documentation and providing practical usage examples for shader-based APIs. Focused on clarifying the Impeller requirement for ImageFilter.shader and isShaderFilterSupported, the work included restructuring documentation to improve discoverability and reduce onboarding time for developers. Developed and documented an API example for the Expansible widget, incorporating a new Material API sample and widget test to guide correct implementation. Leveraged Dart and Flutter, with an emphasis on API design, widget development, and testing, the contributions established clear usage patterns and helped prevent common misusage of shader-based filters through example-driven documentation and structured guidance.
