打开相机时抖动image_picker崩溃

Question

我正在尝试使用image_picker在Flutter上，它在Android模拟器上运行完美。但是当我尝试在我的真实设备上使用它时，当我点击按钮打开相机时，它崩溃了，没有给出任何错误。我该如何解决它？我的手机是Android（小米8）。

我的代码：

 File? _image;
  final imagePicker = ImagePicker();

  Future getImage() async {
    final image = await imagePicker.pickImage(source: ImageSource.camera);
    setState(() {
      _image = File(image!.path);
    });
  }

ElevatedButton(
                onPressed: getImage,
                child: Text("Foto"),
              ),

Container(
      height: 300,
      width: 300,
      decoration: BoxDecoration(
        color: Colors.red,
      ),
      child: _image == null
          ? Text("No image selected")
          : CircleAvatar(
              backgroundImage: FileImage(_image!),
            )),
    ),

您必须添加访问图像的权限。适用于IOS

<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app does not require access to the microphone.</string>
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>

对于Android

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
