Answer from AI
Flutter supports a variety of user gestures that can be handled using widgets like GestureDetector, Listener, and others. The main types of gestures:
- Tap: single tap, double tap, long press.
- Drag: horizontal, vertical, free movement.
- Scale: pinch and spread gestures.
- Pan: moving the finger across the screen with tracking of speed and direction.
- Swipe: quick movements in a specific direction.
Example of handling tap and drag:
GestureDetector(
onTap: () {
print('Tap');
},
onPanUpdate: (details) {
print('Move: ${details.delta}');
},
child: Container(
color: Colors.blue,
width: 200,
height: 200,
),
)
Thus, Flutter provides flexible tools for handling various user gestures.
