Flutter webview popup not working

Flutter WebView Popup Not Working

When working with Flutter’s WebView, you may encounter situations where popups or new browser windows are not functioning as expected. This is primarily due to security restrictions imposed by modern web standards.

To provide an example and solution for this, consider a scenario where you have a WebView widget in your Flutter app and need to handle popups or new windows. Let’s assume you’re using the `webview_flutter` package for this implementation.

Firstly, ensure that you have imported the necessary package in your project’s dependencies:

      sdk: flutter
   webview_flutter: ^2.0.0+3

Next, set up the WebView widget in your app’s code:

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

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

class _WebViewExampleState extends State {
  void initState() {
    // Enable popups for the webview
    WebView.platform = SurfaceAndroidWebView();

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('WebView Popup Example'),
      body: WebView(
        initialUrl: 'https://example.com',
        javascriptMode: JavascriptMode.unrestricted,

void main() {
    home: WebViewExample(),

In this code snippet, we have created a simple WebView widget that initializes with a URL and enables JavaScript execution.

In order to handle the popups, it is crucial to set the `WebView.platform` to `SurfaceAndroidWebView()` in the `initState()` method. This will override the default WebView behavior and enable popups to work properly on Android devices.

For iOS devices, the popups should work by default without any additional configuration.

With this setup, you should now be able to navigate popups or new windows within your WebView widget. Remember to adapt the code to your specific use case and customize it further as needed.
