flutter clean && flutter pub get

无论您的代码在何处：

bool isStoragePermission = true;
bool isVideosPermission = true;
bool isPhotosPermission = true;

// Only check for storage < Android 13
DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
if (androidInfo.version.sdkInt >= 33) {
  isVideosPermission = await Permission.videos.status.isGranted;
  isPhotosPermission = await Permission.photos.status.isGranted;
} else {
  isStoragePermission = await Permission.storage.status.isGranted;
}

if (isStoragePermission && isVideosPermission && isPhotosPermission) {
  // no worries about crash 
} else {
  // write your code here
}
