initState() method of first activity is not initializing after taking popback stack from the aother activity

Question

I am working on flutter application where I am using 3 screens.

MainActivity open to ActivityClass1 and ActivityClass1 will open ActivityClass2. Now when I am taking Navigator.pop(context), from ActivityClass2 it will shows ActivityClass1 from the stack. But this time I need to take initState() of ActivityClass1 as I need to refresh few data on ActivityClass1.

Is there any way to call initState() of ActivityClass1 which also maintain my stack for MainActivity -> ActivityClass1? I have also tried for Navigator.of(context).pushAndRemoveUntil( instead of using Navigator.pop(context), on ActivityClass2 but this will clears my stack.

Solution

Navigator.push returns a Future when the MaterialPageRoute passed into it is resolved. You could await that Future to know when some other view has popped back to it.

Example,

Navigator.of(context).push(MaterialPageRoute(
  builder: 
    (context) => NewView(),
  ),
).then((_) {
  // Call setState() here or handle this appropriately
});

So now when I am coming back to my Activity Class1 this method will help to take any action while comming back to screen by just using Navigator.pop(context),.

I have tried the same solution but this can create a stack like MainActivity() -> Screen1 -> Screen1. So now when I press back from screen1 it will pop again to Screen1.

If I will use the Navigator.push call again then this screen will also be added to my stack, so now if I'll press back this will show me like Screen1 -> Screen2 -> Screen1 -> MainActivity. Which is the wrong flow. I need something where it works as screen1 -> MainActivity in my stack after pressing back from screen2.
