Receive Response from pop navigator in Flutter

Question

Here is a simple example of code that navigator push for a form called. and pop for an answer. my goal is to make a pop of an object, not a string, but keeping it that simple st

Answer 1

Add await to receive the result from Future and return the value;

   Future getFormData(BuildContext context) async {
    final result = await Navigator.push(
        context, MaterialPageRoute(builder: (context) => MyCustomForm()));
    return Future.value(result);
  }

Modify the FloatingActionButton onPressed code to receive Future String

onPressed: () async {
            final value = await getFormData(context);
            setState(() {
              data = value;
            });
          },
