CallbackAssetLoader class
Convenience class that extends FileAssetLoader and allows you to register a callback for loading Rive assets.
The callback will be called for each asset that needs to be loaded manually. See RiveFile for additional options. Which assets are embedded are defined within the Rive editor.
This callback will be triggered for any referenced assets.
Set loadCdnAssets
to false to disable loading
assets from the Rive CDN.
Example usage:
Loading from assets. Here only assets marked as referenced will trigger the callback.
final riveFile = await RiveFile.asset(
'assets/asset.riv',
loadCdnAssets: true,
assetLoader: CallbackAssetLoader(
(asset, bytes) async {
final res =
await http.get(Uri.parse('https://picsum.photos/1000/1000'));
await asset.decode(Uint8List.view(res.bodyBytes.buffer));
return true;
},
),
);
