fetchState method

dynamic fetchState()

Fetches any parsed data from the previous component/page route as either a List or a Map.

Casting can be done afterwards to get the desired outcome

void init() {
  dynamic data = fetchState();
  if (data is Map) {
    print(data['a']);
  } else if (data is List) {
    print(data[0]);
  }
}

Implementation

dynamic fetchState() => r.fetchState();
