youtube_player_iframe is not working on iOS

Question

I want to play YouTube videos using youtube_player_iframe(5.1.2).
Android can be played on both emulators and devices without any problems. However, iOS does not display the player.
They told me to write down more details, but there's no errors or anything.
What are the causes and solutions? Thanks.

main.dart

import 'package:flutter/material.dart';
import 'package:youtube_player_iframe/youtube_player_iframe.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            
            YoutubePlayerScaffold(
              controller: YoutubePlayerController.fromVideoId(
                videoId: 'jNQXAC9IVRw',
                autoPlay: true,
                params: const YoutubePlayerParams(
                  showVideoAnnotations: false,
                  strictRelatedVideos: true,
                  color: 'red',
                )
              ),
              builder: (context, player) {
                return player;
              },
            ),

          ],
        ),
      ),
    );
  }
}

Tried exactly the same code on iPhone 15 pro simulator and it worked.

My flutter doctor output.

gem which cocoapods
/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods.rb

The only thing I can suggest is to try updating Flutter and Cocapods.

If that doesn't work. Then you can try the good old "Flutter app works on Android but doesn't work on IOS trick".

cd ios
flutter clean
rm -rf Pods
rm -rf Podfile.lock
flutter pub get
pod install
