removeDispatcher static method

void removeDispatcher(Component component, { required bool hasDrag, required bool hasScale, })

Decrements the reference counts for component's event types and disables the corresponding recognizer flags when the count reaches zero.

Implementation

static void removeDispatcher(
  Component component, {
  required bool hasDrag,
  required bool hasScale,
}) {
  final game = component.findRootGame();
  if (game == null) {
    return;
  }
  final dispatcher = game.findByKey(
    const MultiDragScaleDispatcherKey(),
  ) as MultiDragScaleDispatcher?;
  if (dispatcher == null) {
    return;
  }
  if (hasDrag) {
    dispatcher._disableDrag();
  }
  if (hasScale) {
    dispatcher._disableScale();
  }
}
