Draggable with a descendent containing an onTap() throws exception on Web when dragging

Question

Draggable with a descendent containing an onTap() throws exception on Web when dragging

philip-brink opened this issue 4 years ago · comments

Description

When on web, a Draggable or LongPressDraggable with a child containing an onTap() method will throw an exception and fail to update when starting to drag. It is also not possible to exit the dragging state, and the application will need to be restarted.

See the example on DartPad.

This issue possibly relates to issues #66887 and #67044.

Steps to Reproduce

From main.dart:

  @override
  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // Here we take the value from the MyHomePage object that was created by
        // the App.build method, and use it to set our appbar title.
        title: Text(widget.title),
      ),
      body: ListView(
        children: [
          LongPressDraggable(
            feedback: Material(
              child: Container(
                height: 20,
                width: 20,
                color: Colors.green,
              ),
            ),
            child: ListTile(
              title: Text('Click'),
              onTap: () {
                print('tapped');
              },
            ),
            childWhenDragging: Container(
              height: 20,
              color: Colors.pinkAccent,
            ),
          ),
        ],
      ),
    );
  }

To reproduce the bug when on Web, hold and drag the ListTile.

Expected results: The Draggable's feedback should appear (in this case a green box) and be able to be dragged.

Actual results: The Draggable's feedback appears, but does not follow the mouse while dragging. In the console, two different exceptions are thrown:

Uncaught Error: This widget has been unmounted, so the State no longer has a context (and should be considered defunct).
Uncaught Error: Assertion failed: file:///opt/flutter/packages/flutter/lib/src/rendering/mouse_tracking.dart:301:12 !_debugDuringDeviceUpdate

It then becomes impossible to exit the dragging state, and the application must be restarted.

When on Android emulator, the dragging behaves as expected.

Logs

The first exception thrown is about the State no longer having a context. This happens once upon starting to be dragged.

errors.dart:167 Uncaught Error: This widget has been unmounted, so the State no longer has a context (and should be considered defunct).
Consider canceling any active work during "dispose" or using the "mounted" getter to determine if the State is still active.

The second exception is about the assertion failing. This happens on every mouse movement while the dragging process should be happening.
