loadStructuredBinaryData<T> method
Retrieve ByteData from the asset bundle, parse it with the given function, and return that function's result.
The result is not cached by the default implementation; the parser is run each time the resource is fetched. However, some subclasses may implement caching (notably, subclasses of CachingAssetBundle).
Implementation
Future<T> loadStructuredBinaryData<T>(String key, FutureOr<T> Function(ByteData data) parser) async {
return parser(await load(key));
}
