XFileCapturedCallback typedef

XFileCapturedCallback = bool Function(XFile, CameraPickerViewType)

The callback type definition when the XFile is captured by the camera. 拍摄文件生成后的回调

Return true if it has handled arguments. 如果在回调中已经进行了处理，请返回 true。

Future<void> _onXFileCaptured() async {
  XFile? _fileToBeHandle;
  await CameraPicker.pickFromCamera(
    context,
    pickerConfig: CameraPickerConfig(
      onXFileCaptured: (XFile file, CameraPickerViewType viewType) {
        // Pass the file out of the saving method's scope.
        _fileToBeHandle = file;
        // Pop twice without any result to exit the picker.
        Navigator.of(context).pop();
      },
    ),
  );
  // Continue your custom flow here.
  print(_fileToBeHandle?.path);
}

Notice about the implementation

• After the callback is implemented and returned true, the default viewer page will not be presented anymore.

在实现时需要注意

• 实现了该方法且返回 true 后，默认的预览页面不会再出现。
