check your MaterialApp() widget, if you set localizationsDelegates ,may be you well get this problem. it works when i delete those code.

              localizationsDelegates: [
                  DefaultCupertinoLocalizations.delegate,
              ],

my codes.

MaterialApp(
              navigatorKey: navigatorKey,
              title: 'test',
              theme: ThemeData(
                  platform: TargetPlatform.iOS,
                  backgroundColor: Color(0xfff1f1f1),
                  accentColor: AppStyle.colorPrimary,
                  primaryColor: AppStyle.colorPrimary,
                  buttonColor: AppStyle.colorPrimary,
                  iconTheme: IconThemeData(color: Colors.white),
                  textTheme: TextTheme(
                      title: TextStyle(color: Colors.white),
                  ),
                  primaryTextTheme: TextTheme(title: TextStyle(color: Colors.white)),
                  primaryIconTheme: const IconThemeData.fallback().copyWith(
                      color: Colors.white,
                  ),
                  appBarTheme: AppBarTheme().copyWith(brightness: Brightness.dark),
              ),
              home: LoginPage(),
              debugShowCheckedModeBanner: false,
              onGenerateRoute: AppRouter.router.generator,
          )
