在 image_picker 插件中拍照后黑屏
Black Screen after taking photo in image_picker plugin
我正在使用最新版本的 image_picker
插件,包括 Flutter 2.0.3 版本,而且这在真实设备(小米 Redmi Note 7)上失败了。我能看到的唯一消息是 Lost connection to我拿相机时的设备。图库作品fine.This是我的代码
import 'dart:io';
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(
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
File _image;
final picker = ImagePicker();
Future getImage() async {
final pickedFile = await picker.getImage(source: ImageSource.camera);
setState(() {
if (pickedFile != null) {
_image = File(pickedFile.path);
} else {
print('No image selected.');
}
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Image Picker Example'),
),
body: Center(
child: _image == null
? Text('No image selected.')
: Image.file(_image),
),
floatingActionButton: FloatingActionButton(
onPressed: getImage,
tooltip: 'Pick Image',
child: Icon(Icons.add_a_photo),
),
);
}
}
我已经全部添加了permissions.How可以解决这个问题吗?
添加到清单android:requestLegacyExternalStorage="true"
android {
compileSdkVersion 29
// ....
defaultConfig {
targetSdkVersion 29
