Flutter Ui Implementation Standard

• FORBIDDEN: Do NOT substitute design assets with Flutter's built-in Icons.* unless explicitly requested or if the asset is missing.

2. Coding Standards

Goal: Prevent common lint errors (like const_with_non_const) and ensure clean code.

• Rule 2.1: Const Correctness:
  • BorderRadius.circular(N) is NOT CONST.
  • Correct (Const): BorderRadius.all(Radius.circular(N))
  • Correct (Non-Const): Remove const keyword if using BorderRadius.circular.
• Rule 2.2: Theming:
  • Define all colors and gradients in AppTheme / AppColors first.
  • Use ShaderMask for gradient text.
  • Use Container with BoxDecoration for gradient backgrounds.

3. Implementation Process

1. Analyze: Review design screenshots and raw asset files.
2. Prepare Assets: Rename and move all required assets to assets/images/.
3. Prepare Theme: Update AppTheme with necessary colors and styles.
4. Implement: Build Widgets using the renamed assets and theme.

4. PAGE Components (CRITICAL)

Goal: Keep each screen maintainable by splitting page-specific UI blocks into components/.

• PAGE component path (this repo): lib/src/features/<feature>/presentation/components/
• PAGE components: layout blocks and UI pieces only used by that page
• Rule: Page file is a composition root; delegate blocks to components/ widgets
