GenUI Development Helper

This skill provides workflows and best practices specific to the genui repository.

Workflows

1. Running Tests and Fixes

The repository uses a custom tool to run tests, apply fixes, and format code before committing. It should typically only be run before committing, since it is inefficient and slow to run it on every change.

It will run dart fix --apply, dart format, and flutter test on all packages in the repository.

Command:

dart run tool/test_and_fix/bin/test_and_fix.dart

When to use:

• Before committing changes, to ensure project health.
• Instead of running flutter test manually for each project in the repo.

2. Creating a New Component in the genui package

When creating a new UI component in genui:

1. Location: Place component files in packages/genui/lib/src/components/.
2. Inheritance: Components must extend UiComponent.
3. A2UI Compliance: Ensure the component matches the A2UI specification.
4. Documentation: Follow strict Dart documentation standards.

3. Updating Documentation

• Documentation source of truth is in docs/.
• Use mkdocs context if mentioned, but primarily edit the markdown files directly.
• Ensure strict adherence to "Natural Writing" standards (no AI-isms).

Key Constants & Patterns

• Current A2UI Version: v0.9
• State Management: Uses SurfaceController from genui.

References

• A2UI Specification

- Available in the submodule at @packages/genui/submodules/a2ui - The specification documentation is available in @packages/genui/submodules/a2ui/specification/v0.9/docs - The specification schemas are available in @packages/genui/submodules/a2ui/specification/v0.9/json - Because it is a submodule, you may need to update the submodule to get the latest specification.
