ImmediateMultiDragGestureRecognizer constructor Null safety

ImmediateMultiDragGestureRecognizer(
  1. {Object? debugOwner,
  2. @Deprecated('Migrate to supportedDevices. ' 'This feature was deprecated after v2.3.0-1.0.pre.') PointerDeviceKind? kind,
  3. Set<PointerDeviceKind>? supportedDevices}
)

Create a gesture recognizer for tracking multiple pointers at once.

It's possible to limit this recognizer to a specific set of PointerDeviceKinds by providing the optional supportedDevices argument. If supportedDevices is null, the recognizer will accept pointer events from all device kinds.

Implementation

ImmediateMultiDragGestureRecognizer({
  super.debugOwner,
  @Deprecated(
    'Migrate to supportedDevices. '
    'This feature was deprecated after v2.3.0-1.0.pre.',
  )
  super.kind,
  super.supportedDevices,
});
