It can be implemented in your application.

        imageId = await ImageDownloader.downloadImage("https://raw.githubusercontent.com/wiki/ko2ic/image_downloader/images/flutter_no.png").catchError((error) {
          print(error);
        }).timeout(Duration(seconds: 10), onTimeout: () {
          print("timeout");
        });

In addition, added error handling in v13.0.2.

HTTP error code can be acquired from PlatformException.
The file in case of error was deleted on Android.
Fix to return correct file path on iOS.

Thank you for your quick update. The dart timeout() gives us a good timeout except when the permission dialog appears. and the app doesn't crash. we can catch the error.
