executeInitialized<R> method

FutureOr<R> executeInitialized<R>(ExecuteInitializedCallback<R> callback, { Initializable? parent, })

Executes the callback ensuring that this instances was fully initialized.

Implementation

FutureOr<R> executeInitialized<R>(
  ExecuteInitializedCallback<R> callback, {
  Initializable? parent,
}) {
  if (isInitialized) {
    return callback();
  }

  var ret = ensureInitialized(parent: parent);

  if (ret is Future<InitializationResult>) {
    return ret.then((result) {
      if (!result.ok) {
        throw InitializationError(this, "Error initializing (async): $this");
      }
      return callback();
    });
  } else {
    if (!ret.ok) {
      throw InitializationError(this, "Error initializing: $this");
    }

    return callback();
  }
