Recognizes movement both horizontally and vertically on a per-pointer basis.
In contrast to PanGestureRecognizer, ImmediateMultiDragGestureRecognizer watches each pointer separately, which means multiple drags can be recognized concurrently if multiple pointers are in contact with the screen.

Methods
-
createNewPointerState(
PointerDownEvent event) → _ImmediatePointerState -
Subclasses should override this method to create per-pointer state objects to track the pointer associated with the given event.
-
toStringShort(
) → String -
Returns a very short pretty description of the gesture that the recognizer looks for, like 'tap' or 'horizontal drag'.
-
acceptGesture(
int pointer) → void -
Called when this member wins the arena for the given pointer id.
inherited -
addPointer(
PointerDownEvent event) → void -
Registers a new pointer that might be relevant to this gesture detector.
inherited -
dispose(
) → void -
Releases any resources used by the object.
inherited -
invokeCallback(
String name, RecognizerCallback callback) → dynamic -
Invoke a callback provided by the application and log any exceptions.
inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited -
rejectGesture(
int pointer) → void -
Called when this member loses the arena for the given pointer id.
inherited -
toString(
) → String -
Returns a string representation of this object.
