Why Can't I Use WebView In Flutter Dart?-CodePudding

I installed webview_flutter. I ran pub get too. also, I added Import 'package:webview_flutter/webview_flutter.dart'. But actually I can't use WebView widget In flutter. This is my code. WebView occured not found error.

import 'dart:io'; // Add this import.
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

class WebViewExample extends StatefulWidget {
  @override
  _WebViewExampleState createState() => _WebViewExampleState();
}

class _WebViewExampleState extends State<WebViewExample> {
  @override
  void initState() {}
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
      title: const Text('WebView Example'),
    ),
    body: Builder(builder: (BuildContext context){
      return WebView(
        initialUrl: 'https://flutter.dev',
      );
    }),
    );
  }
}

CodePudding user response：

You need a WebViewWidget and a WebViewController

 @override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(title: const Text('Flutter Simple Example')),
    body: WebViewWidget(controller: controller),
  );
}

1- The Webview supports SDK 19 on Android and 9.0 on IOS so check in the SDK Manager for your SDK version and update it... and check your minSdkVersion in your android build gradle

Or it could be a network issue so...

2- Test it on an actual device if it works then you need to do the following modifications if you're using a virtual device

Press Windows -> Search for View Network Connections -> Right Click on your network -> Properties -> Click on TCP IPv4 -> Properties -> Check Use the following DNS Server -> Change to 8.8.8.8 the first one and 0.0.0.0 the second one
