how can implement onTap node and onLongtap on node tree graph

[nabil6391]

You wrap the widget as with a GestureDetector

 Widget getNodeText(int i) {
    return GestureDetector(
  onLongPressStart: (details){
    var x = details.globalPosition.dx;
    var y = details.globalPosition.dy;
    Offset(x,y);
  },
  child: Container(
      padding: EdgeInsets.all(16),
      decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(4),
        boxShadow: [
          BoxShadow(color: Colors.blue[100], spreadRadius: 1),
        ],
      ),
      child: Text("Node $i")),
);
}

} `
