Answer 1

Something like this in build method of your state

    Widget build(BuildContext context) => FutureBuilder<YourData>(
    future: doRequest(),
    builder: (context, snapshot) {
      if (snapshot.connectionState == ConnectionState.done) {
        ... /* return widget with data from network response */
      } else {
        return Center(child: CircularProgressIndicator());
      }
    });
