flutter_animated

Animated images (GIF/APNG/WebP) support in flutter.

The plugin is under construction.

It lacks of basic features, and has got a number of serious issues.

USAGE

require it

in pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  flutter_animated: any

basic usage

// import
import 'flutter_animated/animated_gif.dart';

// fetch a gif
final Uint8List imgBytes = await http.readBytes('https://some.site/some.gif');

// generate a Widget for the gif
final Widget gifWidget = new AnimatedGif.memory(imgBytes);

NOTES

Currently the only format being supported is gif and the only constructor is .memory.

AnimatedGif inherits from Image and StatefulWidget. This may change in the future though.

The performance is way not ideal for now. The good news is, it shows the first frame while decoding.

TODO

• POOR PERFORMANCE it takes seconds to decode large images
  • checkout low level ImageProvider, ImageStream, RawImage, etc.
  • or use the platform for high performance
