2	Reactive State Management	final name = ''.obs; final isLogged = false.obs; final count = 0.obs; final balance = 0.0.obs; final number = 0.obs; final items = [].obs; final myMap = {}.obs; Obx(() =>Text('${count.value}')); onPressed: () => increment()
3	Simple State Management	class Controller extends GetxController {} static Controller get to => Get.find(); update(); GetBuilder() init: Controller(), builder: (controller) => Text('${controller.counter}')
4	Reactive State Controller	GetX() init: Controller(), builder: (controller) => Text() In 'Controller' class: final count = 0.obs;    void increment() {      count.value++;    }    void clearCount() {      count.value = 0;    }    void onInit() { {      super.onInit();      ever(count, (_));      everAll([count], (_));      once(count, (_));      debounce(count, (_));      interval(count, (_))    }
5	Simple State Controller	final controller = Get.put(Controller()); GetBuilder() id: 'count1', builder: (controller) =>Text() In 'Controller' class: int count = 0;    void increment() {      count++;      update();    }    void clearCount() {      count = 0;      update();    }
6	Dependency Management	Instancing methods   Get.put()   Get.lazyPut()   Get.putAsync()   Get.create()   Get.delete() Find controller   final controller = Get.find< Controller>();   Controller controller = Get.find(); Alternate controller   Get.replace()   Get.lazyReplace() Binding   void dependency(){}   Named route > getPages > BindingBuilder() > void Function   Named route   initialBinding SmartManagement   ✰ full   onlyBuilder   keepFactory
7	Internationalization	Custom class   @override   Map< String, Map< String, String>> get keys tr > Text('key'.tr) @key > trParams({'key':'value'}) translations   Custom class that extends Translations locale   Locale()   Get.deviceLocale()   Get.updateLocale() fallbackLocale   Locale()
8	Change Theme	void main() async {   await GetStorage.init();   runApp(const MyApp()); } Create theme file Config lightTheme & darkTheme Change theme dynamically   Get.isDarkMode > bool   Get.changeThemeMode()   Get.changeTheme() Store them in local storage   GetStorage() > read() & write()
9	GetX Service & GetView	void main() async {   WidgetsFlutterBinding.ensureInitialized();   await initServices();   runApp(const MyApp()); } GetView< SettingsService> late SharedPreferences _prefs; final counter = 0.obs;
