flutter error get_it

 [ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: Bad state: GetIt: Object/factory with type loginService is not registered inside GetIt. 

(Did you accidentally do GetIt sl=GetIt.instance(); instead of GetIt sl=GetIt.instance;

Did you forget to register it?)

해결 방안

await setupLocator(); 선언 해주어야 한다.

void main() async {

/*  WidgetsFlutterBinding.ensureInitialized() is required in Flutter v1.9.4+ 
 *  before using any plugins if the code is executed before runApp. 
 */
  WidgetsFlutterBinding.ensureInitialized();


// Configure injecction
   await setupLocator();

   runApp(MyApp());
}
