loadLavaAsset method

Future<void> loadLavaAsset(String assetPath)

Loads a Lava animation from the specified asset path.

The assetPath should point to a directory containing a manifest.json file and the required image atlas frames. This directory must be included in the pubspec.yaml assets section.

Example:

controller.loadLavaAsset('assets/animations/fire_loop');

Implementation

Future<void> loadLavaAsset(String assetPath) async {
  final manifestData = await rootBundle.loadString("$assetPath/manifest.json");
  final manifest = LavaManifest.fromJson(jsonDecode(manifestData));
  final images = <ui.Image>[];

  for (final image in manifest.images) {
    final imageData = await rootBundle.load("$assetPath/${image.url}");
    final codec = await ui.instantiateImageCodec(imageData.buffer.asUint8List());
    final frame = await codec.getNextFrame();

    images.add(frame.image);
  }

  asset = LavaAsset(
    images: images,
    manifest: manifest,
  );

  frameIndex = 0;
  notifyListeners();
}
