[FIXED] Flutter Navigation push Replacement is not working when not placed in the first activity

Issue

I have several Page.
1. Start Page
2. Page 2
3. Page 3
4. Main Menu

From 1 -> 2. and 2 -> 3. i use this for navigation :

Navigator.of(context).push(new MaterialPageRoute<MyPage>(
                    builder: (BuildContext context) {
                      return new MyPage();
                    },
                  ));

and for 3 -> 4. I want to use this (Push Replacement, will not going back), but it doesnt work and act like normal Push:

Navigator
        .of(context)
        .pushReplacement(new MaterialPageRoute(builder: (BuildContext context) {
      return new MainMenuPage();
    }));

Confusing.

Solution

I had the same problem going on, guess it was due to the fact that my screen #3 came from a dialog and i wasn't disposing of it before. So what I did was:

Navigator.of(context).popUntil((route) => route.isFirst);

then

Navigator.pushReplacement(context, MaterialPageRoute(builder: (BuildContext context) => NewPage()));
