googlemap - searchMapPlaceWidget inside bottomsheetwidget

[Error Place]

hi guys. i am setting up a map inside a bottomsheet so the user can search a location and set their location by adding a marker . but for some reason the marker is not getting added after search is done and instead it shows up when the bottomsheet is disposed . and i am getting this message inside dart console

[VERBOSE-2:ui_dart_state.cc(157)] Unhandled Exception: setState() called after dispose(): _SearchMapPlaceWidgetState#4107e(lifecycle state: defunct, not mounted, tickers: tracking 0 tickers)

This error happens if you call setState() on a State object for a widget that no longer appears in the widget tree (e.g., whose parent widget no longer includes the widget in its build). This error can occur when code calls setState() from a timer or an animation callback.

The preferred solution is to cancel the timer or stop listening to the animation in the dispose() callback. Another solution is to check the "mounted" property of this object before calling setState() to ensure the object is still in the tree.

This error might indicate a memory leak if setState() is being called because another object is retaining a reference to this State object after it has been removed from the tree. To avoid memory leaks, consider breaking the reference to this object during dispose().

#0      State.setState.<anonymous clos<…>

does anyone know what i am doing wrong with the state?

thank you all in advenced

Show us your setState() code.

That is the place where you used setState in your code.

Okay I think you will have to wrap setState() inside if (this.mounted){

set state((){})}

i have two other setState in that same page which belongs to two other functions?

_submit() async {
  if (_formKey.currentState.validate()) {
    _formKey.currentState.save();

    setState(() {
      _isLoading = true;
    });

_handleImageFromGallery() async {
  File imageFile = await ImagePicker.pickImage(source: ImageSource.gallery);
  if (imageFile != null) {
    setState(() {
      _profileImage = imageFile;
    });
  }
}
