Dropdown remains static on iPhone app about dropdown_button2

Please make a minimal reproducible example.

this is the screenshot of Flutterflow test mode, where the widget nicely unfolds.
On the iphone, is does not unfold at all.

[cnickel76]

this is the code of my custom widget in Flutterflow:
// Automatic FlutterFlow imports
import '/backend/backend.dart';
import '/backend/schema/structs/index.dart';
import '/backend/supabase/supabase.dart';
import '/flutter_flow/flutter_flow_theme.dart';

import '/custom_code/widgets/index.dart'; // Imports other custom widgets
import '/custom_code/actions/index.dart'; // Imports custom actions
import '/flutter_flow/custom_functions.dart'; // Imports custom functions
import 'package:flutter/material.dart';
// Begin custom widget code
// DO NOT REMOVE OR MODIFY THE CODE ABOVE!

import 'package:dropdown_button2/dropdown_button2.dart';

// ignore: must_be_immutable
class MyDDWidget2 extends StatefulWidget {
@OverRide
MyDDWidget2({

//This rebuilds the StatefulWidget to update the button's text

Unfortunately, I can't help with that. I can't run the code given.

I'll need a minimal reproducible example.

[cnickel76]

Well I do not know what to add here... the code that I pasted was simply taken from your pub.dev package webpage.

[AhmedLSayed9]

Yes, but I can't run that sample. It has dependencies that I don't have:

import '/backend/backend.dart';
import '/backend/schema/structs/index.dart';
import '/backend/supabase/supabase.dart';
import '/flutter_flow/flutter_flow_theme.dart';
import '/flutter_flow/flutter_flow_util.dart';
import '/custom_code/widgets/index.dart'; // Imports other custom widgets
import '/custom_code/actions/index.dart'; // Imports custom actions
import '/flutter_flow/custom_functions.dart'; // Imports custom functions

Also, you should put the code refactored into a code block like the above one.
