How to fix NDK missing even after android studio configured?

Question

I am trying to use flutter_webview_plugin to implement webview in my flutter application but it pops up the error while running. Details given below. But if I run simple hello world app it runs successfully.

import 'package:flutter/material.dart';
import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';
void main() => runApp(MaterialApp(
home: MyApp(),
debugShowCheckedModeBanner: false,
darkTheme: ThemeData.dark(),
)
);



class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
@override
Widget build(BuildContext context) {
return WebviewScaffold(
  appBar: AppBar(
    title: Text('KnowledgeSuttra',
      textAlign: TextAlign.center,
    )
  ),
  url: 'www.knowledgesuttra.com',
);
}
}

Errors I am getting * Error running Gradle: ProcessException: Process "J:\FlutterStudioProjects\knowledge_suttra\android\gradlew.bat" exited abnormally:

I expect to load webview successfully. Thanks in adv

You could try `sdkmanager --licenses`. This will prompt you to accept licenses. `flutter doctor` might work as well. — Daniel V., Jun 02 '19 at 09:10

If you are using NDK, verify the ndk.dir is set to a valid NDK directory. It is currently set to
C:\Users\~UserName~\AppData\Local\Android\sdk\ndk-bundle

Where: Build File 'C:\Users\~UserName~\AndroidStudioProjects\sandwich\android\app\build.gradle'

If you face this error, make sure if NDK is available in the given path or not., The path is present in the error, which is something like C:\Users\~UserName~\AppData\Local\Android\sdk\ndk-bundle.. Verify if the files exist there, otherwise change that from project structure.

To access Project Structure, go to File -> Other Settings -> Default Project Structure. It will show a window as below.
