Philosophy
The Lemonade Design System embraces flexibility over rigidity. We provide sensible defaults and semantic APIs, but acknowledge that design requirements vary.
Core Principles
- Semantic First — Always prefer semantic tokens over raw values
- Type Safety — Leverage each platform's type system to prevent misuse
- Consistency — Use the design system to maintain visual harmony
- Flexibility — Access lower-level primitives when necessary, with clear warnings
- Performance — Theme changes animate smoothly via interpolation
Documentation Standards
All public APIs must be thoroughly documented with:
- Clear description of purpose and usage
- Code examples showing common use cases
- Parameter documentation with types and defaults
- Preconditions and constraints clearly stated
Contributing
We welcome contributions! Please see the platform-specific documentation for detailed contribution guidelines:
General Guidelines
- Design Validation — Components must be validated by the design team before implementation
- Figma First — Public components must exist in Figma with "Ready for Dev" status
- Documentation — All public APIs require comprehensive documentation
- Testing — Include unit tests and widget/UI tests for components
- Code Review — All changes require at least one approval
