Constructors

CoreGestureDetector({Key key, Widget child, GestureTapDownCallback onTapDown, GestureTapUpCallback onTapUp, GestureTapCancelCallback onTapCancel, GestureLongPressStartCallback onLongPressStart, GestureLongPressMoveUpdateCallback onLongPressMoveUpdate, GestureLongPressEndCallback onLongPressEnd, GestureScaleStartCallback onScaleStart, GestureScaleUpdateCallback onScaleUpdate, GestureScaleEndCallback onScaleEnd, HitTestBehavior behavior, bool excludeFromSemantics: false, DragStartBehavior dragStartBehavior: DragStartBehavior.start, CanDragDownFunction canHDragDown, CanDragDownFunction canVDragDown})

Properties

behavior HitTestBehavior
How this gesture detector should behave during hit testing. [...]
final
canHDragDown CanDragDownFunction
final
canVDragDown CanDragDownFunction
final
child Widget
The widget below this widget in the tree. [...]
final
dragStartBehavior DragStartBehavior
Determines the way that drag start behavior is handled. [...]
final
excludeFromSemantics bool
Whether to exclude these gestures from the semantics tree. For example, the long-press gesture for showing a tooltip is excluded because the tooltip itself is included in the semantics tree directly and so having a gesture to show it would result in duplication of information.
final
hashCode int
The hash code for this object. [...]
@nonVirtual, read-only, inherited
key Key
Controls how one widget replaces another widget in the tree. [...]
