Flutter Web: If you put a file on the drag zone, an error occurs as shown below.

Can you give some sample code which could reproduce this issue?

I tested desktop_drop example with flutter 3.0.1 , but it seems work fine.

Patrick386 commented 2 years ago

I don't know what I did wrong. Here is the sample code.

Sample code ``` import 'package:desktop_drop/desktop_drop.dart'; import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); // This widget is the root of your application. @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, ), home: const MyHomePage(title: 'Flutter Demo Home Page'), ); } } class MyHomePage extends StatefulWidget { const MyHomePage({Key? key, required this.title}) : super(key: key); final String title; @override State createState() => _MyHomePageState(); } class _MyHomePageState extends State { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(widget.title), ), body: Center(child: _DropTest()), // This trailing comma makes auto-formatting nicer for build methods. ); } } class _DropTest extends StatefulWidget { const _DropTest({Key? key}) : super(key: key); @override State<_DropTest> createState() => _DropTestState(); } class _DropTestState extends State<_DropTest> { @override Widget build(BuildContext context) { return DropTarget( onDragDone: (DropDoneDetails detail) async { print('Detail:${detail.files.first.name}'); }, onDragUpdated: (DropEventDetails details) { }, onDragEntered: (DropEventDetails detail) { }, onDragExited: (DropEventDetails detail) { }, child:Container( width: 600, height: 60, color: Colors.amber, alignment: Alignment.center, child: const Text('Attach files by dragging & dropping, selecting them.'), ), ); } } ```

I have the same issue too, any update about it?

Patrick386 commented 1 year ago

I forgot about this because of other tasks. At that time, I had tested this sufficiently. My guess is that this issue appears to be caused by overlapping drop areas. Testing with a Stack widget can indeed be helpful in identifying the problem.

Same here, it throws error only after reloading.
