# WebView for Flutter (Developers Preview)
|
||||
|
||||
[](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).
|
||||
|
||||
## Developers Preview Status
|
||||
The plugin relies on Flutter's new mechanism for embedding Android and iOS views.
|
||||
As that mechanism is currently in a developers preview, this plugin should also be
|
||||
considered a developers preview.
|
||||
|
||||
Known issues are tagged with the [platform-views](https://github.com/flutter/flutter/labels/a%3A%20platform-views) and/or [webview](https://github.com/flutter/flutter/labels/p%3A%20webview) labels.
|
||||
|
||||
To use this plugin on iOS you need to opt-in for the embedded views preview by
|
||||
adding a boolean property to the app's `Info.plist` file, with the key `io.flutter.embedded_views_preview`
|
||||
and the value `YES`.
|
||||
|
||||
## Setup
|
||||
|
||||
### iOS
|
||||
Opt-in to the embedded views preview by adding a boolean property to the app's `Info.plist` file
|
||||
with the key `io.flutter.embedded_views_preview` and the value `YES`.
|
||||
|
||||
## 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 widget's Dartdoc for more details on how to use the widget.

# Launch Screen Assets
|
||||
|
||||
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
|
||||
|
||||
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
