dragStartBehavior property Null safety
final
Determines the way that drag start behavior is handled.
If set to DragStartBehavior.start, the drag gesture used to dismiss a dismissible will begin at the position where the drag gesture won the arena. If set to DragStartBehavior.down it will begin at the position where a down event is first detected.
In general, setting this to DragStartBehavior.start will make drag animation smoother and setting it to DragStartBehavior.down will make drag behavior feel slightly more reactive.
By default, the drag start behavior is DragStartBehavior.start.
See also:
- DragGestureRecognizer.dragStartBehavior, which gives an example for the different behaviors.
