Why flutter only showing WHITE SCREEN in release mode

Question

I have no idea what's going on, No errors has been thrown in Debug Mode (it works and render fine) However, after running futter run --release the home screen is not showing only white screen

This is my main.dart file, I'm using GetX as route tool main.dart

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      title: 'Sample App',
      theme: ThemeData(
        backgroundColor: Colors.white,
        primarySwatch: Colors.grey,
      ),
      //defaultTransition: Transition.zoom,
      home: const Login(),
      getPages: [
        GetPage(name: "/login", page: () => const Login()),
        GetPage(name: "/register", page: () => const Register()),
      ],
    );
  }
}

This is my login.dart login.dart

Scaffold(
      resizeToAvoidBottomInset: false,
      backgroundColor: Colors.white,
      body: Container(
          width: Get.width,
          margin: kDefaultBodyMargin,
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [
              const Spacer(),
              Container(
                margin: const EdgeInsets.only(top: 30.0),
                child: TextField(),
              ),
              Container(
                margin: const EdgeInsets.only(top: 30.0),
                child: TextField(),
              ),
              const Spacer(flex: 5),
              Container(
                margin: EdgeInsets.only(bottom: Get.height * 0.05),
                child: SizedBox(
                  width: Get.width,
                  height: 54,
                  child: TexButton(),
                )
              ),
            ],
          ),
        ),
      )

Answer 2

because of the GetX package -> GetMaritalApp you used, I faced that problem today and tried all day long to solve it.

tried to downgrade the version of Get package put didn't work, so I simply get rid of it, not simply actually that took me time.

and BTW tried all solutions in https://github.com/flutter/flutter/issues/70558

Hope that helped, and Hope they will fix it soon.
