decodeImage method
Decode a WebP formatted file stored in bytes
into an Image.
If it's not a valid webp file, null is returned.
If the webp file stores animated frames, only the first image will
be returned. Use decodeAnimation to decode the full animation.
Implementation
@override
Image? decodeImage(List<int> bytes, {int frame = 0}) {
startDecode(bytes);
_info!.frame = 0;
_info!.numFrames = 1;
return decodeFrame(frame);
}
