Recognizes taps on a per-pointer basis.
MultiTapGestureRecognizer considers each sequence of pointer events that could constitute a tap independently of other pointers: For example, down-1, down-2, up-1, up-2 produces two taps, on up-1 and up-2.

Properties
- longTapDelay → Duration
-
The amount of time between onTapDown and onLongTapDown.

-
A pointer that might cause a tap is still in contact with the screen at a particular location after longTapDelay.
read / write - onTap → GestureMultiTapCallback
-
A tap has occurred.
read / write - onTapCancel → GestureMultiTapCancelCallback
-
The pointer that previously triggered onTapDown will not end up causing a tap.
read / write - onTapDown → GestureMultiTapDownCallback
-
A pointer that might cause a tap has contacted the screen at a particular location.
read / write - onTapUp → GestureMultiTapUpCallback
-
A pointer that will trigger a tap has stopped contacting the screen at a particular location.
read / write - hashCode → int
-

Methods
-
acceptGesture(
int pointer) → void -
Called when this member wins the arena for the given pointer id.
-
addPointer(
PointerEvent event) → void -
Registers a new pointer that might be relevant to this gesture detector.
-
dispose(
) → void -

-
rejectGesture(
int pointer) → void -
Called when this member loses the arena for the given pointer id.
-
toStringShort(
) → String -
Returns a very short pretty description of the gesture that the recognizer looks for, like 'tap' or 'horizontal drag'.
-
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 -
toString(
) → String -
