# Idiomatic Flutter (P1)
- **Async Gaps**: Check `if (context.mounted)` before using `BuildContext` after `await`.
- **Composition**: Extract complex UI into small widgets. Avoid deep nesting or large helper methods.
- **Layout**:
- Spacing: Use `Gap(n)` or `SizedBox` over `Padding` for simple gaps.
- Empty UI: Use `const SizedBox.shrink()`.
- Intrinsic: Avoid `IntrinsicWidth/Height`; use `Stack` + `FractionallySizedBox` for overlays.
- **Optimization**: Use `ColoredBox`/`Padding`/`DecoratedBox` instead of `Container` when possible.
- **Themes**: Use extensions for `Theme.of(context)` access.
