Flutter|Как изменить цвет кнопки AlertDialog?

Question

[Евгений]

Всем привет!
Молю о помощи.
Имеется StatefulWidget в котором вызываю AlertDialog, создал initState и setState, но цвет кнопки меняется только если закрыть и ещё раз открыть AlertDialog, а не сразу при нажатии.

import ...

class HomeScreen extends StatefulWidget {

  @override
  State<HomeScreen> createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  late String _addField;
  late IconData _selectedValue;
  late bool _active;

  @override
  void initState() {
    _addField = 'Pusto';
    _active = false;
    _selectedValue = Icons.delete_forever_outlined;
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: Scaffold(
        body: Padding(
          padding: const EdgeInsets.only(left: 8, right: 8),
          child: Column(children: [
            ActiveTaskInfo(
              task: tasks.first,
            ),
            const TextWidget(),
            Expanded(child: TasksList()),
          ]),
        ),
        //bottomNavigationBar: const BottomBar(),
        //floatingActionButton: FloatingButton(),
        floatingActionButton: FloatingActionButton(
          onPressed: () {
            showDialog(
                context: context,
                builder: (BuildContext context) {
                  return AlertDialog(
                    title: const Text('Add Task'),
                    content: TextField(onChanged: (String value) {
                      _addField = value;
                    }),
                    actions: [
                      DropdownButton<IconData>(
                        value: _selectedValue,
                        onChanged: (IconData? newValue) {
                          setState(() {
                            _selectedValue = newValue!;
                          });
                        },
                        items: dropdownItems,
                      ),
                      ElevatedButton(
                          onPressed: () {
                            setState(() {
                              tasks.addAll({
                                TaskData(
                                    taskName: _addField,
                                    tagNameOne: 'Work',
                                    tagNameTwo: 'Rasion Project',
                                    icon: _selectedValue,
                                    taskTime: '00:32:10')
                              });
                              decorations.addAll({
                                TaskTagsDecorations(
                                    firstTagTextColor: const Color(0xffFD5B71),

                            });
                            Navigator.of(context).pop();
                          },
                          child: const Text('Add')),
                      ElevatedButton(
                        onPressed: () {
                          setState(() {
                            _active = !_active;
                          });
                        },
                        child: Text('Work'),
                       style: ButtonStyle(
                          backgroundColor:
                              MaterialStateProperty.all(_active ? Colors.blue : Colors.red)
                          ),

Вопрос закрыт.
Нужно было обернуть в StatefulBuilder:

StatefulBuilder(builder: (context, myState) {
                    return ElevatedButton(
                      onPressed: () {
                        myState(() {
                          _active = !_active;
                        });
                      },
                      child: Text('Work'),
                      style: ButtonStyle(
                          backgroundColor: MaterialStateProperty.all(
                              _active ? Colors.blue : Colors.red)),
                    );
                  }),
