[image_picker]On iOS13 device, pickVideo does not work. #41046
Description
1.Problem
pickVideo method returns a selected File.
But my App can not touch the File!
(file.copy(), file.readAsBytesSync() does not work.)
2.Source code
import 'package:flutter/material.dart';
import 'package:image_picker/image_picker.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: RaisedButton(
onPressed: _showImagePicker,
child: Text('Image Picker'),
),
), // This trailing comma makes auto-formatting nicer for build methods.
);
}
void _showImagePicker() async {
var image = await ImagePicker.pickVideo(source: ImageSource.gallery);
print(image.path);
print(image.statSync());
}
}

5-a) Reason (I think)
Because the File path contains [PluginKitPlugin]Folder.
(App have No permission for the Directory)
Like [/private/var/mobile/Containers/Data/PluginKitPlugin/xxx/tmp/trim.xxx.MOV].
5-b) on iOS12
On iOS12 device, works fine!
Like[/private/var/mobile/Containers/Data/Application/xxx/tmp/xxx.MOV]
