+# WebView for Flutter
+
+[![pub package](https://img.shields.io/pub/v/webview_flutter.svg)](https://pub.dartlang.org/packages/webview_flutter)
+
+A Flutter plugin that provides a WebView widget.
+
+On iOS the WebView widget is backed by a [WKWebView](https://developer.apple.com/documentation/webkit/wkwebview);
+On Android the WebView widget is backed by a [WebView](https://developer.android.com/reference/android/webkit/WebView).
+
+## Usage
+Add `webview_flutter` as a [dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/).
+
+You can now include a WebView widget in your widget tree. See the
+[WebView](https://pub.dev/documentation/webview_flutter/latest/webview_flutter/WebView-class.html)
+widget's Dartdoc for more details on how to use the widget.
+
+
+
+## Android Platform Views
+The WebView is relying on
+[Platform Views](https://flutter.dev/docs/development/platform-integration/platform-views) to embed
+the Android’s webview within the Flutter app. By default a Virtual Display based platform view
+backend is used, this implementation has multiple
+[keyboard](https://github.com/flutter/flutter/issues?q=is%3Aopen+label%3Avd-only+label%3A%22p%3A+webview-keyboard%22).
+When keyboard input is required we recommend using the Hybrid Composition based platform views
+implementation. Note that on Android versions prior to Android 10 Hybrid Composition has some
+[performance drawbacks](https://flutter.dev/docs/development/platform-integration/platform-views#performance).
+
+### Using Hybrid Composition
+
+To enable hybrid composition, set `WebView.platform = SurfaceAndroidWebView();` in `initState()`.
+For example:
+
+```dart
+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',
+    );
+  }
+}
+```
+
+`SurfaceAndroidWebView()` requires [API level 19](https://developer.android.com/studio/releases/platforms?hl=th#4.4). The plugin itself doesn't enforce the API level, so if you want to make the app available on devices running this API level or above, add the following to `<your-app>/android/app/build.gradle`:
+
+```gradle
+android {
+    defaultConfig {
+        // Required by the Flutter WebView plugin.
+        minSdkVersion 19
+    }
+  }
+```
