  @override
  initState() {
    screens = [
      {
        "screen": DistanceScreen(),
        "title": Text(S.of(context).DistanceScreenTranslate) 
      },

  void selectPage(int index) {
    setState(() {
      selectedPageIndex = index;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        centerTitle: true,
        leading: Padding(
          padding: const EdgeInsets.all(4.0),
          child: Image.asset(
            'assets/icons/double-arrow.png',
            height: 5,
            width: 5,
          ),
        ),
        title: screens[selectedPageIndex]["title"],

You can use :

WidgetsBinding.instance!.addPostFrameCallback((_) async { $place your state to init here });

It could be async or not.

make sure to listen: false if using provider.

Text(S.of(context).DistanceScreenTranslate) : you do not have access to BuildContext in initState because it is yet to be created. Consider using same statements inside didChangeDependecies method. It is safe option to access BuildContext before build method.
