Switch not switch the bool

[visign3d]

tried a simple switch, it stays always in initial value

Same error here

Probably just not doing state management correctly. Is this code inside a StatefulWidget or StatelessWidget? If Stateful, you need to call setState when you change a value so that the widget gets rebuilt.

ok, i just miss understood the naming of the switchtile widgets. The name initialvalue , is the actual switch value.
SettingsTile.switchTile( initialValue: controller.darkTheme.value, onToggle: (s) => controller.darkTheme.value = s,
you should change the initial value to actually get the switch animation

Could you explain your code?
I have this, the switch works but it stays in the initial value:

bool darktheme= UserPreferences.getDarkMode();

SettingsTile.switchTile(
              onToggle: (value) {
                print("Dark mode changed" + value.toString());
                setState(() {
                  darktheme= value;
                });
              },
              initialValue: darktheme,
              leading: Icon(Icons.format_paint),
              title: Text('Enable custom theme'),

Not sure what is wrong in your, code , seems good to me. I am using GetX package, which don't use statefull class to change states.

try to move setState otside the widget tree:

void switchMode(bool s) {
    setState(() {
      darkmode = s;
    });
  }


SwitchListTile(
              initialvalue: darkmode,
              onChanged: (s) => switchMode(s),
            ),

Same here. Worked correctly with StatefulWidget, but not with Provider package. The build method doesn't seem to be called after notifyChanges().

SettingsTile.switchTile(
  initialValue: context.select((SettingsViewModel viewModel) => viewModel.enableNotification),
  onToggle: (value) {
    context.read<SettingsViewModel>().setEnableNotification(value);
  },
  title: const Text("通知オン"),
),

void setEnableNotification(bool value) async {
  final prefs = await SharedPreferences.getInstance();
  prefs.setBool(_enableNotificationKey, value);
  notifyListeners();
}

I am also having problems with this. The below code does not toggle the widget. However, the print statement works and changes the variable once.

SettingsTile.switchTile(
                                onToggle: (bool value) {
                                  setState(() {
                                    print(surrender);
                                    surrender = value;
                                  });
                                },
                                initialValue: surrender,
                                leading: Icon(Icons.format_paint),
                                title: Text('S17'),
                              )

uiのbuildメソッドが動くようにしないといけません。
StatefullWidgetなら、SetState()を実行してください。

[yadaniyil]

The switch state is controlled by your own state management — you need to call setState (or your state management equivalent) inside onToggle to update initialValue. Please see the updated example app in v3.0.0 for working patterns. If you're still seeing unexpected behavior after upgrading, please open a new issue with a minimal reproduction.
