Plugin that allows Flutter to communicate with native WebView.
Warning: The web display is not integrated in the widget tree, this is the original display above the vibrate display. You will not be able to see snackbars, dialogs, or other vibrating widgets that will overlap the screen area taken by the web display.
The getSafeAcceptedType () function is only available for the minimum SDK 21. The eval () function only supports SDK 19 or greater for evaluating Javascript.
Getting Started
iOS
In order for plugin to work correctly, you need to add new key to ios/Runner/Info.plist
NSAllowsArbitraryLoadsInWebContent is for iOS 10+ and NSAllowsArbitraryLoads for iOS 9
How it works Launch WebView Fullscreen with Flutter navigation
new MaterialApp(
routes: {
"/": (_) => new WebviewScaffold(
url: "https://www.google.com",
appBar: new AppBar(
title: new Text("Widget webview"),
),
),
},
);
Optional parameters are hidden and initialChild is available so you can display other things while waiting for the page to load. If you set hidden to true it will display the default CircularProgressIndicator. If you also specify Widgets for initialChild, you can display them as you like until the page loads.
e.g. The following will show a read screen with the text 'waiting
return new MaterialApp(
title: 'Flutter WebView Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
routes: {
'/': (_) => const MyHomePage(title: 'Flutter WebView Demo'),
'/widget': (_) => new WebviewScaffold(
url: selectedUrl,
appBar: new AppBar(
title: const Text('Widget webview'),
),
withZoom: true,
withLocalStorage: true,
hidden: true,
initialChild: Container(
color: Colors.redAccent,
child: const Center(
child: Text('Waiting.....'),
),
),
),
},
);
Access local files in the file system
Set the withLocalUrl option to true in the launch function or in the Webview scaffold to enable support for local URLs.
Note that, on iOS, the localUrlScope option also needs to be set to path to the directory. All files in this folder (or subfolders) will be allowed access. If removed, only local files opened will have permitted access, so no sub-sources are loaded. This option is ignored on Android.
Ignoring SSL Errors
Set the ignSSLErrors option to true to display content from the server with certificates that Webview does not normally trust such as self-signed certificates.
Warning: Don't use this in production.
Note that on iOS you you need to add new key to ios/Runner/Info.plist
NSAllowsArbitraryLoadsInWebContent is for iOS 10+ and NSAllowsArbitraryLoads for iOS 9. Otherwise you'll still not be able to display content from pages with untrusted certificates.
