GestureRecognizer constructor

GestureRecognizer({
  1. Object? debugOwner,
  2. Set<PointerDeviceKind>? supportedDevices,
  3. AllowedButtonsFilter allowedButtonsFilter = _defaultButtonAcceptBehavior,
})

Initializes the gesture recognizer.

The argument is optional and is only used for debug purposes (e.g. in the toString serialization).

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

GestureRecognizer({
  this.debugOwner,
  this.supportedDevices,
  this.allowedButtonsFilter = _defaultButtonAcceptBehavior,
}) {
  assert(debugMaybeDispatchCreated('gestures', 'GestureRecognizer', this));
}
