    )

Implementation

Future<T?> getData<T>(
    String key, Future<T> Function(String value) parser) async {
  assert(Assets._assets != null, 'Assets.init() must be called first.');
  T? data;
  try {
    data =
        await Assets._assets!.loadStructuredData('$setPath(key)$key', parser);
  } catch (ex) {
    data = null;
  }
  return data;
