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.
