Flutter Cursor Rules
Learn about cursor rules specific to Flutter development.
Flutter-Specific Rules
Cursor rules in Flutter provide intelligent navigation and manipulation capabilities designed specifically for mobile development with Flutter. These rules help you work more efficiently with Flutter widgets, state management, and platform-specific code.
Widget Navigation
- Navigate between widget definitions
- Jump to state class declarations
- Move between build methods
Smart Selection
- Select widget trees and expressions
- Expand selection to include widget parameters
- Smart state variable usage selection
Code Manipulation
- Quick widget insertion
- Automated state handling
- Build method management
Best Practices
- Use widget-aware navigation
- Leverage state-specific cursor movements
- Utilize build method-aware selection
Examples
// Navigate between widget definitions
class CustomButton extends StatelessWidget {
final String title;
final VoidCallback onPress;
const CustomButton({
Key? key,
required this.title,
required this.onPress,
}) : super(key: key);
@override
Widget build(BuildContext context) {
return ElevatedButton(
style: ElevatedButton.styleFrom(
padding: const EdgeInsets.all(12),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(8),
),
),
onPressed: onPress,
child: Text(
title,
style: const TextStyle(
fontSize: 16,
fontWeight: FontWeight.bold,
),
),
);
}
}
// Smart selection of state management
class ProfileScreen extends StatefulWidget {
final String userId;
const ProfileScreen({Key? key, required this.userId}) : super(key: key);
@override
_ProfileScreenState createState() => _ProfileScreenState();
}
class _ProfileScreenState extends State {
String? photoUrl;
Future takePhoto() async {
final picker = ImagePicker();
final image = await picker.pickImage(source: ImageSource.camera);
if (image != null) {
setState(() {
photoUrl = image.path;
});
}
}
@override
Widget build(BuildContext context) {
return Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
if (photoUrl != null)
CircleAvatar(
radius: 100,
backgroundImage: FileImage(File(photoUrl!)),
),
const SizedBox(height: 16),
CustomButton(
title: 'Take Photo',
onPress: takePhoto,
),
],
),
);
}
}
