Flutter app freezes when running under Android Studio

My flutter application has somewhat heavy model initialization. So it is created in async function. And future produced by this function is passed to a widget. While the model loads - I would like to display progress indicator. The problem is when I launch my app from Android Studio - progress indicator freezes and app never displays anything else! It is worth mentioning that sometimes it works. But very rare to be honest.

This reproduces both on android emulator and real device. It never freezes if launched from the device itself. It also never freezes if launched in debug mode from Android Studio.

I have created a minimal reproducing sample:

import 'package:flutter/material.dart';

Future<int> getTheAnswer() async {
  // To emulate long running method
  await Future.delayed(Duration(seconds: 10));
  return 42;
}

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  var theAnswer = getTheAnswer();
  // This is just to show that the future was indeed completed
  theAnswer.then((value) => print("Future completed with $value"));
  runApp(MyApp(theAnswer));
}

class MyApp extends StatelessWidget {
  final Future<int> _myFuture;

  MyApp(this._myFuture);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: Scaffold(
          body: Center(
              child: FutureBuilder<int>(
        future: _myFuture,
        builder: (context, snapshot) {
          if (!snapshot.hasData) {
            print("No data");
            return CircularProgressIndicator();
          }

          // This part is not executed
          print("Has data");
          return Text(
              "The Answer to the Ultimate Question of Life, the Universe, and Everything is ${snapshot.data}");
        },
      ))),
    );
  }
}

This outputs:
