The operator '[]' isn't defined for the type 'int'. Try defining the operator '[]'

I am trying to add a BottomNavigationBarItem and give it a different icon and label. then I tried to change the pages when you click on them: but it gives me three message errors:

The argument type 'Map<String, Object>' can't be assigned to the parameter type 'String'.

The operator '[]' isn't defined for the type 'int'.
Try defining the operator '[]'.

The argument type 'Object?' can't be assigned to the parameter type 'Widget?'.

When I searched for the solution I have known that it is an sdk-type issue but couldn't know how to solve it without changing the sdk I am kind of new in flutter

class _TaskscreenState extends State<Taskscreen> {
  List<Map<String, Object>> get _pages => [
    {
      'page': provincesScreen(),
      'title': 'org',
    },
    {
      'page': FavouritScreen(),
      'title': 'your favourits',
    },
  ];

  int _selectedpageIndex = 0;
  void _selectedPage(int value) {
    setState(() {
      _selectedpageIndex = value;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar:
          AppBar(title: Text(_pages[_selectedpageIndex['title']])),
      body:_pages[_selectedpageIndex]['page'],
      bottomNavigationBar: BottomNavigationBar(
        onTap: _selectedPage,
        backgroundColor: Colors.blueGrey,
        selectedItemColor: Colors.purple,
        unselectedItemColor: Colors.white,
        currentIndex: _selectedpageIndex,
        items: const [
          BottomNavigationBarItem(
            icon: Icon(Icons.category),
            label: ('categories'),
          ),
          BottomNavigationBarItem(
            icon: Icon(Icons.star),
            label: ('favourites'),
          ),
          BottomNavigationBarItem(
            icon: Icon(Icons.star),
            label: ('Rating'),
          ),
        ],
      ),
    );
  }
}

you put this wrong

  AppBar(title: Text(_pages[_selectedpageIndex['title']])),

correct it to:

  AppBar(title: Text(_pages[_selectedpageIndex]['title'])),
