positioned-tap-detector #

Flutter widget allowing to receive tap callbacks, together with their position on the screen. It supports onTap, onDoubleTap and onLongPress gestures. Each callback function is invoked with TapPosition object that provides global and relative touch position. To adjust maximum time allowed between double-tap gesture consecutive taps, specify an additional doubleTapDelay parameter.

    PositionedTapDetector(
      onTap: (position) => _printTap('Single tap', position),
      onDoubleTap: (position) => _printTap('Double tap', position),
      onLongPress: (position) => _printTap('Long press', position),
      doubleTapDelay: Duration(milliseconds: 500),
      child: ...,
    )
    
    void _printTap(String gesture, TapPosition position) => 
        print('$gesture: ${position.global}, ${position.relative}');
