webview_flutter 2.1.2

A Flutter plugin that provides a WebView widget on Android and iOS.

WebView for Flutter

A Flutter plugin that provides a WebView widget.

On iOS the WebView widget is backed by a WKWebView; On Android the WebView widget is backed by a WebView.

Usage

Add webview_flutter as a dependency in your pubspec.yaml file. If you are targeting Android, make sure to read the Android Platform Views section below to choose the platform view mode that best suits your needs.

You can now include a WebView widget in your widget tree. See the WebView widget's Dartdoc for more details on how to use the widget.

Android Platform Views

The WebView is relying on Platform Views to embed the Android’s webview within the Flutter app. It supports two modes: Virtual displays (the current default) and Hybrid composition.

Here are some points to consider when choosing between the two:

• Hybrid composition mode has a built-in keyboard support while Virtual displays mode has multiple keyboard issues
• Hybrid composition mode requires Android SDK 19+ while Virtual displays mode requires Android SDK 20+
• Hybrid composition mode has performance limitations when working on Android versions prior to Android 10 while Virtual displays is performant on all supported Android versions

	Hybrid composition	Virtual displays
Full keyboard supoport	yes	no
Android SDK support	19+	20+
Full performance	Android 10+	always
The default	no	yes

Using Virtual displays

The mode is currently enabled by default. You should however make sure to set the correct minSdkVersion in android/app/build.gradle (if it was previously lower than 20):

android {
    defaultConfig {
        minSdkVersion 20
    }
}

Using Hybrid Composition

1. Set the correct minSdkVersion in android/app/build.gradle (if it was previously lower than 19):

   android {
       defaultConfig {
           minSdkVersion 19
       }
   }
   

2. Set WebView.platform = SurfaceAndroidWebView(); in initState(). For example:

   import 'dart:io';
      
   import 'package:webview_flutter/webview_flutter.dart';
   
   class WebViewExample extends StatefulWidget {
     @override
     WebViewExampleState createState() => WebViewExampleState();
   }
      
   class WebViewExampleState extends State<WebViewExample> {
     @override
     void initState() {
       super.initState();
           // Enable hybrid composition.
   if (Platform.isAndroid) WebView.platform = SurfaceAndroidWebView();
     }
   
     @override
     Widget build(BuildContext context) {
       return WebView(
         initialUrl: 'https://flutter.dev',
       );
     }
   }
   

Enable Material Components for Android

To use Material Components when the user interacts with input elements in the WebView, follow the steps described in the Enabling Material Components instructions.
