Setting Permission and switch - flutter

Question

I am trying to create a setting page. In it, I would like to have several switches. The user will use them to manage the Permissions, for Camera, Micro and more.
Here is the code I have written, but clearly something is wrong as it is not working properly.
When I tap on the switch, it does not change from On to Off. Also, it does not change the permissions.
I am using:
import 'package:settings_ui/settings_ui.dart';
import 'package:permission_handler/permission_handler.dart';
SizedBox(
height: height,
child: SettingsList(
sections: [
SettingsSection(
title: Text(tPermissions,style: TextStyle(color: Theme.of(context).primaryColor,fontWeight: FontWeight.bold, fontSize: 13.0),
),
tiles: <SettingsTile>[
SettingsTile.switchTile(
leading: const Icon(Icons.camera),
onToggle: (value) {
setState(() {
value = !value;
if (value = false) {
Permission.camera.isDenied;
print (Permission.camera.isDenied);
} else
{
print (Permission.camera.isGranted);
Permission.camera.isGranted;
}
});
},
initialValue: false,
trailing: ChangeCameraWidget(),
title: const Text(tCamera),
),
class ChangeCameraWidget extends StatefulWidget {
const ChangeCameraWidget ({Key? key}) : super(key: key);
#override
State<ChangeCameraWidget> createState() => _ChangeCameraWidgetState();
}
class _ChangeCameraWidgetState extends State<ChangeCameraWidget> {
#override
Widget build(BuildContext context) {
return Switch.adaptive(
value: false,
onChanged: (value) {
if (value = false) {value = true;} else {value = false;}
});
}
}
