Prevent interaction on rest of the page while page transitioning

Prevent page interactions during transitions in general on Android and iOS.

This bug not been noticed. I think it's a very serious bug.

Interestingly this bug does not appear when using the backbutton on your device. Even though you still do a Navigator Push before the transition has ended.
I have have 'fixed' this problem by using fullscreenDialog: true, (though that changes the animation to a vertical one).

This is indeed a severe bug and should be fixed. Also because the crash caused by it stops further interaction with the app.

This is indeed a severe bug and should be fixed.

Who knows when to fix it?

Thanks to the flutter team.

Reproducible on the latest master 1.22.0-10.0.pre.340.

flutter doctor -v

Minimal reproducible code sample

import 'package:flutter/material.dart';
import 'package:flutter/scheduler.dart';

void main() {
  timeDilation = 4.0;
  runApp(MaterialApp(
    title: 'Navigation Basics',
    home: FirstRoute(),
  ));
}

class FirstRoute extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('First Route'),
      ),
      body: Center(
        child: RaisedButton(
          child: Text('Open route'),
          onPressed: () {
            Navigator.push(
              context,
              MaterialPageRoute(builder: (context) => SecondRoute()),
            );
          },
        ),
      ),
    );
  }
}

class SecondRoute extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Second Route"),
      ),
      body: Center(
        child: RaisedButton(
          onPressed: () {
            Navigator.pop(context);
          },
          child: Text('Go back!'),
        ),
      ),
    );
  }
}

Verified this issue on latest versions and observed that tapping on back button in app bar is not recognized. Used physical device for verification. With this I am going ahead and closing as not replicable anymore. If anybody disagrees, please write in comments and I'll reopen it.
