Flutter WebView Keyboard Not Showing – Solution

If you are experiencing issues with the keyboard not showing up in a Flutter WebView, there are a few possible reasons and solutions you can try.

Possible Reason 1: Wrong Configuration

Make sure that you have configured the WebView plugin correctly in your Flutter project. Check that you have added the necessary dependencies in your pubspec.yaml file:

dependencies:
  flutter_webview_plugin: ^0.4.0

Also, ensure that you have registered the WebView plugin in your Flutter app’s main.dart file:

import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'WebView Demo',
      routes: {
        '/': (_) => const MyAppWebview(),
      },
    );
  }
}

class MyAppWebview extends StatefulWidget {
  const MyAppWebview({Key? key}) : super(key: key);

  @override
  _MyAppWebviewState createState() => _MyAppWebviewState();
}

class _MyAppWebviewState extends State<MyAppWebview> {
  final flutterWebViewPlugin = FlutterWebviewPlugin();

  @override
  void initState() {
    super.initState();
    // ...
  }

  @override
  void dispose() {
    flutterWebViewPlugin.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    // ...
  }
}

Possible Reason 2: Keyboard Focus

Ensure that the WebView has keyboard focus, as sometimes the focus might be on another widget instead. You can try manually setting the focus on the WebView widget by using the FocusNode class:

FocusNode webViewFocus = FocusNode();

@override
void initState() {
  super.initState();
  webViewFocus.addListener(_handleFocusChange);
}

@override
void dispose() {
  webViewFocus.removeListener(_handleFocusChange);
  webViewFocus.dispose();
  super.dispose();
}

void _handleFocusChange() {
  if (webViewFocus.hasFocus) {
    // WebView has keyboard focus
  } else {
    // WebView lost keyboard focus
  }
}

@override
Widget build(BuildContext context) {
  return WebView(
    ...
    focusNode: webViewFocus,
  );
}

Possible Reason 3: Conflicting Gestures

Conflicting gestures can sometimes prevent the keyboard from showing. Try modifying the gesture recognition behavior by using the flutter_gesture_detection package. Add the package to your pubspec.yaml file:

dependencies:
  flutter_gesture_detection: ^0.4.0

Then, wrap your WebView widget with a GestureRecognizer widget from the package:

import 'package:flutter_gesture_detection/flutter_gesture_detection.dart';

@override
Widget build(BuildContext context) {
  return GestureDetectorWidget(
    child: WebView(
      ...
    ),
  );
}

Conclusion

If the keyboard is not showing in your Flutter WebView, check the configuration, ensure the WebView has focus, and consider handling conflicting gestures. Hopefully, one of these solutions will help you resolve the issue.
