flutter-idiomatic-flutter
Compose modern Flutter layouts and widgets idiomatically. Use when composing Flutter widget trees, managing layout constraints, or following idiomatic Flutter patterns. (triggers: lib/presentation/**/*.dart, context.mounted, SizedBox, Gap, composition, shrink)
Best use case
flutter-idiomatic-flutter is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Compose modern Flutter layouts and widgets idiomatically. Use when composing Flutter widget trees, managing layout constraints, or following idiomatic Flutter patterns. (triggers: lib/presentation/**/*.dart, context.mounted, SizedBox, Gap, composition, shrink)
Teams using flutter-idiomatic-flutter should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Idiomatic Flutter
## **Priority: P1 (OPERATIONAL)**
Modern Flutter layout patterns and composition techniques.
- **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.
## Anti-Patterns
- ❌ No `if (context.mounted)` after `await` — using BuildContext across async gaps causes crashes
- ❌ `Widget _buildHeader() { … }` helper methods — extract to a `const StatelessWidget` for proper rebuild control and DevTools profiling
- ❌ Accessing a controller or state directly in a widget (`_controller.data`) — use BLoC/Signals to decouple UI from state
- ❌ `Container(width: 0, height: 0)` for empty space — use `const SizedBox.shrink()`Related Skills
