I’m new on Flutter, and i’m trying to do a simple thing: have a selection list with multi choices.
I’m a web developer and this is a native feature usually, but i discovered that’s not the case in Flutter.

I’ve tried to find a good plugin for that, and discovered animated_custom_dropdown.

My problem is that the dropdown doesn’t save any choice. As i’m new on Flutter, i think i’ve some context/state problem, but I can’t figure out which one. I don’t understand what I’m doing wrong.

Choice is not saved

Could someone help me understand or provide a link or example that would help me?

If you know of a better library for simply having a multi-selection dropdown from a future, I’d be interested too!

Thanks in advance!

My current code is basically this:

class _HomeScreenState extends State<HomeScreen>
    with AfterLayoutMixin<HomeScreen> {
  final SkillRepository _skillRepository = injector.get();

  // ...
  List<Skill> _selectedSkills = [];

  // ...
  Future<List<Skill>> _getSkills() async {
    return await _skillRepository.retrieveAll();
  }
  // ...
    FutureBuilder(
        future: _getSkills(),
        builder:
            (BuildContext context, AsyncSnapshot snapshot) {

          if (snapshot.hasData) {
            return CustomDropdown<Skill>.multiSelect(
                hintText: 'Compétences',
                items: snapshot.data.toList(),
                onListChanged: (value) => setState(() {
                  log('changing value to: $value');
                      _selectedSkills = value;
                    }));
          } else {
            return const CircularProgressIndicator();
          }
        }),
