Flutter: WebView Example

There are several packages that can help you implement a web view in your Flutter application. In this article, we’ll use webview_flutter, the most popular plugin for this kind of stuff.

Install The Plugin

Run the following command to add the flutter_webview plugin to your project:

flutter pub add webview_flutter

This is an official plugin made by the Flutter team, and it is updated quite regularly (this tutorial uses the latest version of the plugin).

Implementation

Import webview_flutter into your Dart code:

import 'package:webview_flutter/webview_flutter.dart';

Then create a webview controller:

final _controller = WebViewController()
    ..setJavaScriptMode(JavaScriptMode.unrestricted)
    ..setNavigationDelegate(
      NavigationDelegate(
        onProgress: (int progress) {
          // print the loading progress to the console
          // you can use this value to show a progress bar if you want
          debugPrint("Loading: $progress%");
        },
        onPageStarted: (String url) {},
        onPageFinished: (String url) {},
        onWebResourceError: (WebResourceError error) {},
        onNavigationRequest: (NavigationRequest request) {
          return NavigationDecision.navigate;
        },
      ),
    )
    ..loadRequest(Uri.parse("https://www.kindacode.com"));

Finally, use the controller with the WebViewWidget as shown below:

 WebViewWidget(
            controller: _controller,
          )

The Complete Example

import 'package:flutter/material.dart';

// don't forget this line
import 'package:webview_flutter/webview_flutter.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      // Remove the debug banner
      debugShowCheckedModeBanner: false,
      theme: ThemeData(primarySwatch: Colors.amber),
      title: "Kindacode.comr",
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  MyHomePage({Key? key}) : super(key: key);

  // Create a webview controller
  final _controller = WebViewController()
    ..setJavaScriptMode(JavaScriptMode.unrestricted)
    ..setNavigationDelegate(
      NavigationDelegate(
        onProgress: (int progress) {
          // print the loading progress to the console
          // you can use this value to show a progress bar if you want
          debugPrint("Loading: $progress%");
        },
        onPageStarted: (String url) {},
        onPageFinished: (String url) {},
        onWebResourceError: (WebResourceError error) {},
        onNavigationRequest: (NavigationRequest request) {
          return NavigationDecision.navigate;
        },
      ),
    )
    ..loadRequest(Uri.parse("https://www.kindacode.com"));

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Webview Example'),
      ),
      body: SizedBox(
          width: double.infinity,
          // the most important part of this example
          child: WebViewWidget(
            controller: _controller,
          )),
    );
  }
}

And here’s the result:

You you have a look at your console, you will see some output like this:

flutter: Loading: 10%
flutter: Loading: 30%
flutter: Loading: 76%
flutter: Loading: 100%
