• Update package:archive to >=4.0.0 constraint

• Requires Flutter 3.27 and fix lints.
• Add conditional imports to prevent importing dart:io on Web targets

• Apply Blend mode at layer level

• Update package:archive dependency constraints

• Fixes for some animations generated by lottiefiles.com

• Fix rounding-off error on progress calculation
• Allow missing end values for integer animations

• Use package:http for Lottie.network. This allows to drop dependency on dart:html and be compatible with wasm.
• Fix new lints from Flutter 3.19

• Add support for layer blend mode

• Allow to load Telegram Stickers (.tgs)

Lottie.asset(
  'sticker.tgs',
  decoder: LottieComposition.decodeGZip,
)

• Add renderCache parameter.

Lottie.asset('assets/complex_animation.json',
  renderCache: RenderCache.raster,
)

Opt-in to a special render mode where the frames of the animation are lazily rendered and kept in a cache.
Subsequent runs of the animation are cheaper to render.

There are 2 kinds of caches:

RenderCache.raster: keep the frame rasterized in the cache (as [dart:ui.Image]).
Subsequent runs of the animation are very cheap for both the CPU and GPU but it takes
a lot of memory.
RenderCache.drawingCommands: keep the frame as a list of graphical operations ([dart:ui.Picture]).
Subsequent runs of the animation are cheaper for the CPU but not for the GPU.

• Expose a hook to customize how to decode zip archives. This is useful for dotlottie archives (.lottie) when we want
  to specify a specific .json file inside the archive

Lottie.asset(
  'animation.lottie',
  decoder: customDecoder,
);

Future<LottieComposition?> customDecoder(List<int> bytes) {
  return LottieComposition.decodeZip(bytes, filePicker: (files) {
    return files.firstWhere((f) => f.name == 'animations/cat.json');
  });
}

• Add backgroundLoading parameter to Lottie.asset|network|file|memory.
  If backgroundLoading is true, the animation will be loaded in a background isolate.
  This is useful for large animations that can take a long time to parse and block the UI work.

• Remove the name property from LottieComposition

• imageProviderFactory is not used in .zip file by default anymore.
  To restore the old behaviour, use:

Future<LottieComposition?> decoder(List<int> bytes) {
  return LottieComposition.decodeZip(bytes, imageProviderFactory: imageProviderFactory);
}

Lottie.asset('anim.json', decoder: decoder)

• Disable gradient cache optimization when ValueDelegate.gradientColor is used
• Use DefaultAssetBundle.of in AssetLottie before fallback to rootBundle
• Add BuildContext optional parameter in LottieProvider.load
• Fixed varying opacity stops across keyframes in the same gradient
• Fixed rounded corners for non-closed curves
• Implement auto-orient
• Require Flutter 3.16

• Add backgroundLoading parameter to Lottie.asset|network|file|memory.
  If backgroundLoading is true, the animation will be loaded in a background isolate.
  This is useful for large animations that can take a long time to parse and block the UI work.

• Replace enableRenderCache with renderCache: RenderCache.raster.
  The new class RenderCache allows to specify the cache behaviour:

  • RenderCache.raster: Cache the frames as rasterized images living in the GPU memory.
  • RenderCache.drawingCommands: Cache the frames as a list of graphical operations. This will only save CPU
    work but will use a lot less memory.

• Reduce the max memory used when using enableRenderCache (now limited to 50MB)
• Allow to configure the memory with a global settings:

Lottie.renderCacheMaxMemory = 75000000;
