onDoubleTapDown property
A pointer has contacted the screen with a primary button at the same location twice in quick succession, which might be the start of a double tap.
This triggers immediately after the down event of the second tap.
If this recognizer doesn't win the arena, onDoubleTapCancel is called
next. Otherwise, onDoubleTap
is called next.
See also:
- kPrimaryButton, the button this callback responds to.
- TapDownDetails, which is passed as an argument to this callback.
- GestureDetector.onDoubleTapDown, which exposes this callback.
Implementation
