Usage

Wrap your widget in a Glissando.

import 'package:flutter/material.dart';
import 'package:glissando/glissando.dart';

void main() {
  runApp(MaterialApp(
    home: Glissando(
      child: Row(
        children: [
          Listener(
            onPointerDown: (_) => print("1 down"),
            onPointerCancel: (_) => print("1 cancel"),
            onPointerUp: (_) => print("1 up"),
            child: Container(
              color: Colors.red,
              width: 100,
              height: 100,
            ),
          ),
          Listener(
            onPointerDown: (_) => print("2 down"),
            onPointerCancel: (_) => print("2 cancel"),
            onPointerUp: (_) => print("2 up"),
            child: Container(
              color: Colors.blue,
              width: 100,
              height: 100,
            ),
          ),
        ],
      ),
    ),
  ));
}

When you slide from widget A to widget B, widget A will receive a pointer cancel event, while widget B will receive a pointer down event.

The property PointerEvent.isGlissandoEvent is available for determining if an event was synthesized by this package.

When you lift the pointer, the widget that last got the down event will get the pointer up event.
