flutter_recaptcha_v2_compat not responsive on Android? Don’t Worry, I’ve Got You Covered!

Are you tired of dealing with the frustrating issue of flutter_recaptcha_v2_compat not being responsive on Android? Well, you’re not alone! Many developers have struggled with this problem, but fear not, dear reader, for I’m about to guide you through a step-by-step solution to get your Recaptcha v2 working smoothly on Android devices.

Understanding the Issue

Before we dive into the solution, let’s take a quick look at what’s causing this issue in the first place. The flutter_recaptcha_v2_compat package is a popular plugin used to implement Google’s Recaptcha v2 in Flutter apps. However, when it comes to Android, the plugin’s default behavior can be a bit wonky, resulting in an unresponsive Captcha.

Causes of the Issue

• Webview Height: The default height of the Webview used by the plugin is not sufficient to display the entire Captcha, leading to an unresponsive Captcha.
• Screen Orientation: The plugin doesn’t handle screen orientation changes properly, causing the Captcha to become unresponsive when the device is rotated.
• Android WebView Settings: The Android WebView’s default settings can interfere with the Captcha’s functionality, causing it to malfunction.

The Solution

Now that we’ve identified the causes, let’s get to the solution! To make the flutter_recaptcha_v2_compat plugin responsive on Android, we’ll need to make a few tweaks to the plugin’s configuration and add some custom code to handle the issues mentioned above.

Step 1: Update the Plugin’s Configuration

First, we need to update the plugin’s configuration to use a custom Webview height. Add the following code to your `pubspec.yaml` file:

dependencies:
  flutter:
    sdk: flutter
  flutter_recaptcha_v2_compat: ^1.0.2

Then, in your Dart file, import the plugin and configure it as follows:

import 'package:flutter_recaptcha_v2_compat/flutter_recaptcha_v2_compat.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await FlutterRecaptchaV2Compat.initialize(
    'YOUR_SITE_KEY',
    'YOUR_SECRET_KEY',
    webViewConfig: const WebViewConfig(
      androidChromeCustomView: true,
      androidWebViewClient: true,
    ),
  );
  runApp(MyApp());
}

Step 2: Handle Screen Orientation Changes

To handle screen orientation changes, we’ll add a custom `OrientationBuilder` widget to our Captcha widget:

class CaptchaWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return OrientationBuilder(
      builder: (context, orientation) {
        return FutureBuilder<void>(
          future: FlutterRecaptchaV2Compat.verify(),
          builder: (context, snapshot) {
            if (snapshot.connectionState == ConnectionState.done) {
              // Captcha verified successfully
            } else {
              return RecaptchaV2CompatWidget(
                siteKey: 'YOUR_SITE_KEY',
                size: RecaptchaV2CompatSize.compact,
                theme: RecaptchaV2CompatTheme.dark,
                lang: 'en',
              );
            }
          },
        );
      },
    );
  }
}

Step 3: Customize Android WebView Settings

To customize the Android WebView settings, we’ll create a custom `WebView` widget:

class CustomWebView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return AndroidWebView(
      initialUrl: 'https://www.google.com/recaptcha/api2/anchor',
      javascriptMode: JavascriptMode.unrestricted,
      androidWebViewSettings: AndroidWebViewSettings(
        databaseEnabled: true,
        domStorageEnabled: true,
        javaScriptEnabled: true,
      ),
    );
  }
}

Putting it all Together

Now that we’ve updated the plugin’s configuration, handled screen orientation changes, and customized the Android WebView settings, let’s put it all together:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Recaptcha v2 Demo'),
        ),
        body: CaptchaWidget(),
      ),
    );
  }
}

Testing and Troubleshooting

Once you’ve implemented the solution, test your app on an Android device to ensure the Captcha is responsive and functioning correctly.

Troubleshooting Tips

• Check the Plugin Version: Make sure you’re using the latest version of the flutter_recaptcha_v2_compat plugin.
• Verify Your Site Key and Secret Key: Double-check your site key and secret key to ensure they’re correct and properly configured.
• Android WebView Settings: If you’re still experiencing issues, try adjusting the Android WebView settings to see if it resolves the problem.

Conclusion

And there you have it, folks! With these simple steps, you should now have a fully functional and responsive Recaptcha v2 implementation on Android devices using the flutter_recaptcha_v2_compat plugin. Remember to test and troubleshoot your implementation to ensure everything is working as expected.
