    Use this on navigator push Navigator.push(context).then((value)=>setState((){}); when it pop the screen it will run the setState

    Use this sentence to go to the second page so the function will wait second screen to close

    bool result = await Navigator.push(context);
if(result){setState((){});}

    when u close the second screen use this sentence Navigator.pop(context, true);

    so when u comment has been posted successfully, u will back to screen one and complete the function if result boolean is true, else do nothing.
