GestureRecognizer constructor

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

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,
  AllowedButtonsFilter? allowedButtonsFilter,
}) : _allowedButtonsFilter = allowedButtonsFilter ?? _defaultButtonAcceptBehavior;
