Flutter web：当应用程序安装到主屏幕时，如何修复在 IOS 中向后滑动时的白页

Question

If I swipe back from a very first page of any flutter app installed to home screen from Safari I receive a blank page:

the swiping process picture

It goes back automatically to the first page in three seconds and doesn't appear anymore until the app is reloaded. I used a sample flutter app without any changes to reproduce this behavior.

What I've tried to fix this:

1. WillPopScope as suggested here , but it's only useful in Safari tab and doesn't have any effect on a home screen app. I tried to wrap Scaffold of a home widget and the whole app just to check.
2. Any tricks with Navigator weren't helpful. If I try to pop anything from a home page like this:

    Navigator.of(context).pop();
    Navigator.pushReplacement(context,
        new MaterialPageRoute(builder: (context) => MyHomePage()));

, i (obviously) receive an error: Navigator has no active routes to replace.

3. I also tried to use the fullscreenDialog: true parameter in MaterialPageRoute when navigated to the next page but the blank page on swipe back remains.

How to get rid of this behavior properly?

I am having the same problem and I believe this has not been solved yet. Looks to be tracked by this (and related) issue: https://github.com/flutter/flutter/issues/76478
