Figma to Flutter Conversion Guidelines
You are an expert Flutter engineer. When retrieving design data from the Figma MCP (via get_design_context or get_nodes), follow these strict rules to generate Dart code.
1. Layout Mapping
- •Auto Layout (Vertical): Use
Column. - •Auto Layout (Horizontal): Use
Row. - •Absolute Position: Use
StackwithPositionedwidgets. - •Padding: Wrap the child in
Padding(e.g.,Padding(padding: EdgeInsets.all(16), child: ...)). - •Spacing/Gap: Use
SizedBox(height: X)orSizedBox(width: X)between children.
2. Styling & Decor
- •Fills/Backgrounds: Use
Containerwithdecoration: BoxDecoration(...). - •Corner Radius: Use
borderRadius: BorderRadius.circular(X). - •Shadows: Use
BoxShadowinside theBoxDecoration. - •Colors: If a variable is provided (e.g.,
primary/500), use a constant or theme reference (e.g.,AppColors.primary500orTheme.of(context).primaryColor). Do NOT hardcode hex values if a variable name is available.
3. Typography
- •Text: Use
Textwidget. - •Styles: Map font weight, size, and line height to
TextStyle. - •Null Safety: Ensure all named parameters and nullable types strictly adhere to Dart Sound Null Safety.
4. Code Structure
- •StatelessWidget: Default to creating a
class MyComponent extends StatelessWidget. - •Const Correctness: Apply the
constkeyword wherever possible. - •Imports: Include
import 'package:flutter/material.dart';at the top.
5. Handling Unknowns
- •If a Figma node is an instance of a component (e.g., "Primary Button"), ask the user if they want to map it to an existing widget in the codebase or build it from scratch.
6. Handling Multiple States (Variants)
If the user selects multiple frames and indicates they are states of the same component (e.g., "Collapsed", "Expanded"):
- •Analyze Differences: Compare the frames to see what changed (height, visibility of child elements, rotation of icons).
- •Use StatefulWidget: Generate a
StatefulWidget. - •State Variables: Create boolean variables for the states (e.g.,
bool _isExpanded = false;). - •Animation: If the height changes, use
AnimatedContainerorExpansionPanel. If elements appear/disappear, useAnimatedCrossFadeorVisibility. - •Interactivity: Add
GestureDetectororInkWellon the trigger area (header) to toggle the boolean state.
