Gif Decode then Encode throws exception: Could not getPixels for frame 1

[can-bigpay]

Hi thank you for this package. I need a little help using the GifDecoder and GifEncoder 🙏

    ByteData bytes = await rootBundle.load(asset);

    // Decode the bytes to [Image] type
    final gifInfo = img.GifDecoder().startDecode(bytes.buffer.asUint8List());

    final encoder = img.GifEncoder();

    for (int i = 0; i < gifInfo!.numFrames; i++) {

      final image =
          img.GifDecoder().decode(bytes.buffer.asUint8List(), frame: i);

      encoder.addFrame(image!);
    }
    final result = encoder.finish()!;

I want to manipualte some pixels later but for now I cannot even decode then encode the same gif.When I check the gif info I can see all the frames however when I display this in flutter or from outside of the app it only shows first frame and throws

[ERROR:flutter/lib/ui/painting/multi_frame_codec.cc(109)] Could not getPixels for frame 1

════════ Exception caught by image resource service ════════════════════════════
The following _Exception was thrown resolving an image frame:
Exception: Could not getPixels for frame 1

I tried to not pass frame to decode function aswell but same output.

    ByteData bytes = await rootBundle.load(asset);

    final image = img.decodeGif(bytes.buffer.asUint8List());
    return img.encodeGif(image!);

Any help is appreciated I'm so lost
