Question

我的Flutter应用似乎卡在了两个视图之间，login_view和home_view。仅在Android中发生此问题。知道为什么会这样吗？这和我的Android模拟器有关吗？预先谢谢你！

login_view_model.dart

class LoginViewModel extends BaseModel {

  final AuthenticationService _authenticationService = locator<AuthenticationService>();
  final DialogService _dialogService= locator<DialogService>();
  final NavigationService _navigationService = locator<NavigationService>();

  Future login ({@required String email, @required String password}) async {
    setBusy(true);
    var result = await _authenticationService.loginWithEmail(email: email, password: password);
    setBusy(false);

    if (result is bool) {
      if (result) {
        _navigationService.navigateTo(HomeViewRoute);
      } else {
        await _dialogService.showDialog(title: 'Login Failure', description: 'General login failure. Please try again later');
      }
    } else {
      await _dialogService.showDialog(title: 'Login Failure', description: result);
    }
  }

  void navigateToSignUp() {
    _navigationService.navigateTo(SignUpViewRoute);
  }
}

home_view.dart

class HomeView extends StatelessWidget {
  const HomeView({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Text('Home'),
    );
  }
}

通常对于每次导航，您的页面都应使用Material（也可以是Material / Scaffold / SafeArea）进行包装
