MultiTapGestureRecognizer class
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.

- Creates a multi-tap gesture recognizer. [...]
Properties
- debugDescription → String
-
Returns a very short pretty description of the gesture that the
recognizer looks for, like 'tap' or 'horizontal drag'.
read-only, override
- longTapDelay ↔ Duration
-
The amount of time between onTapDown and onLongTapDown.
read / write
- onLongTapDown ↔ GestureMultiTapDownCallback
-
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
- debugOwner → Object
-
The recognizer's owner. [...]
final, inherited
- hashCode → int
-
The hash code for this object. [...]
read-only, inherited
- runtimeType → Type
-
A representation of the runtime type of the object.
