loadStructuredData<T> method

@override Future<T> loadStructuredData<T>(String key, Future<T> parser(String value))

Retrieve a string 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

@override
Future<T> loadStructuredData<T>(
    String key, Future<T> Function(String value) parser) {
  if (!_enableStructuredDataTracing) {
    return _bundle.loadStructuredData(key, parser);
  }
  final outerSpan = _hub.getSpan();
  return _wrapLoad(
    outerSpan,
    'loadStructuredData',
    key,
    () => _bundle.loadStructuredData(
      key,
      (value) => _wrapParser(
        outerSpan,
        key,
        () => parser(value),
      ),
    ),
  );
}
