i have a little problem with the Navigator in flutter. I have 3 windows: (Login -> Home -> Orders). But when I go from Login to Home, everything works fine, but if I go from Home to Orders and use the android back button, it returns me to the Login window, that is, until the first view, not the second.

My code Navigation of Login:

```
Navigator.of(context).push(
  MaterialPageRoute(
    builder: (context) => HomeScreen(),
  ),
);

```

My Code Navigation of HomeScreen

```
Navigator.push(this.context,
  MaterialPageRoute(
    builder: (context) =\> Orders(
      numTable: numTable,
    ),
  )
);

```
