native_animated_image 0.3.2

Native (Rust + system ImageIO/ImageDecoder) decoder for animated GIF / APNG / WebP / AVIF. Bypasses Flutter Skia multi-frame codec.

native_animated_image

Native (Rust) decoder & renderer for animated GIF / APNG / WebP in Flutter.

Bypasses Flutter's built-in Skia multi_frame_codec to avoid long-standing upstream bugs:

• flutter/flutter#85831 — Could not getPixels for frame N (open 4+ years)
• flutter/flutter#94205 — Some frames of gif are decoded incorrectly (open 4+ years)

Usage

import 'package:native_animated_image/native_animated_image.dart';

// From bytes (e.g. via your own cache manager / network client)
Image(
  image: NativeAnimatedImageProvider.memory(gifBytes, tag: 'unique-key'),
)

// From a custom byte loader (recommended for production — bring your own
// HTTP client / cache layer)
Image(
  image: NativeAnimatedImageProvider.fromBytesProvider(
    loader: () async => myCacheManager.getBytes(url),
    tag: url,
  ),
)
