What are all num referring to ?
class Sample {  int num;  void method() {    num = 1;    int num = num = 2;    num = 3;  } }

Once again, where did you get the context from?

The context is getting called from Fragment.java. We can use context as long as our class is extends to Fragment.
@Nullable    public Context getContext() {        return mHost == null ? null : mHost.getContext();    }

In Flutter, we can easily initialize int StreamBuilder using this way:
final _loginError = BehaviorSubject<int>.seeded(-1); Stream<int> get loginErrorStream => _loginError.stream;But how can we initialize HashMap List StreamBuilder?
final _list = BehaviorSubject<List<HashMap<int, ABC>>>.seeded();  // 1 positional argument(s) expected, but 0 found. Try adding the missing arguments.

Can you show startActivityForResult code?

Sorry for the late reply. Can you explain what are you trying to achieve?

I guess is because of the  android:layout_marginTop and  android:paddingTop, which make the bottom navigation bar to bottom.
Try this code
<com.google.android.material.bottomnavigation.BottomNavigationView            android:id="@+id/navigationProfile"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:background="@color/white"            android:fitsSystemWindows="true"            app:labelVisibilityMode="labeled"            app:layout_constraintBottom_toBottomOf="parent"            app:layout_constraintHorizontal_bias="1.0"            app:layout_constraintLeft_toLeftOf="parent"            app:layout_constraintRight_toRightOf="parent"            app:layout_constraintTop_toBottomOf="@+id/cardViewUser"            app:menu="@menu/my_navigation_items" />

Congratulations!

Update us once you tried.

Does it work?

You may try and see

Maybe change the height to match_parent?

android:layout_height="812dp" to android:layout_height="match_parent"

Can you screenshot both UI and paste here?

Thank providing me with such an honour ! I will continue to do my best
