I am using youtube_player_flutter plugin version 9.0.1 to play youtube videos in my app, but it gives following error –

The following assertion was thrown building RawYoutubePlayer(dirty, dependencies: [InheritedYoutubePlayer], state: _RawYoutubePlayerState#d7415):
A platform implementation for `flutter_inappwebview` has not been set. Please ensure that an implementation of `InAppWebViewPlatform` has been set to `InAppWebViewPlatform.instance` before use. For unit testing, `InAppWebViewPlatform.instance` can be set with your own test implementation.
'package:flutter_inappwebview_platform_interface/src/in_app_webview/platform_inappwebview_widget.dart':
Failed assertion: line 202 pos 7: 'InAppWebViewPlatform.instance != null'

This is the code where I am using this plugin-

import 'package:flutter/material.dart';
import 'package:fitness_project/models/workout.dart';
import 'package:youtube_player_flutter/youtube_player_flutter.dart';

class WorkoutDetail extends StatefulWidget{
  Workout? workout;
  WorkoutDetail({super.key,this.workout});

  @override
  WorkoutDetailState createState() => WorkoutDetailState(workout: workout);
}

class WorkoutDetailState extends State<WorkoutDetail>{
  Workout? workout;
  WorkoutDetailState({this.workout});

  YoutubePlayerController controller = YoutubePlayerController(
    initialVideoId: 'CbggneVFrx8',
    flags: YoutubePlayerFlags(autoPlay:false,
    ),
  );

  @override
  Widget build(BuildContext context) {
   return Scaffold(
       appBar: AppBar(automaticallyImplyLeading: false,
         backgroundColor: Colors.indigoAccent,
    title: Text(("Workout Details"),
    style:const TextStyle(color: Colors.white)),
    ),
    backgroundColor: Colors.black,
     body: Container(
         child: Center(
             child:Container(
                 child:Column(mainAxisAlignment: MainAxisAlignment.center ,
                   children: [
                     YoutubePlayer(
                       controller: controller,
                     ),
                     
                     Container(decoration: BoxDecoration(border: Border.all(color: Colors.white),
                         color: Colors.white24,
                         borderRadius: BorderRadius.all(Radius.circular(15)) ),
                       height: 150,
                       padding: EdgeInsets.only(top:10,bottom: 20),
                       margin: EdgeInsets.only(left: 20,right:20,top:15,bottom:15),
                       child: Column(children: [

                         Text("Steps to do this workout ",style: TextStyle(color: Colors.white, fontSize: 24)),

                         Divider(color: Colors.white, indent: 10,endIndent:10  ),

                        Expanded(child: Container(
                         child:  Text("Put your hands on ground and jump ",
                             style: TextStyle(color: Colors.white, fontSize: 19)), ))

           ],)
                     )],
                 ))))
   );
  }
}

I have set minSdkVersion to 21 android.useAndroidX=true and android.enableJetifier=true and android gradle plugin version is 7.3.0. I am new to flutter and any help will be much appreciated.
