Are you sure you have already searched for the same problem?
Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!
If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.
In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE]
or ios WKWebView [MY ERROR HERE]
keywords.
Following these steps can save you, me, and other people a lot of time, thanks!

Description
I'm using the package to display a webpage that contains a print service done by popping a blank page containing an HTML receipt and then using
window.print()
js function Expected behavior: the blank page pops displaying the content and then the function is executed and an OS print page appears with the contentCurrent behavior: a blank page is popped but with a white background and no functions are exected the log says that the popped page is
about:blank#blocked
and the console log gives me a document error (probably for executingwindow.print()
on a blocked page)Steps to reproduce
run the following code with any website that has a print mechanism
Dart Code
```dart void main() async{ WidgetsFlutterBinding.ensureInitialized(); runApp(const WebViewScreen()); }class WebViewScreen extends StatefulWidget { const WebViewScreen({Key? key}) : super(key: key);
@override State createState() => _WebViewScreenState();
}
class _WebViewScreenState extends State with WidgetsBindingObserver {
InAppWebViewController? webViewController; InAppWebViewSettings settings = InAppWebViewSettings( isInspectable: kDebugMode, mediaPlaybackRequiresUserGesture: false, allowsInlineMediaPlayback: true, iframeAllow: "camera; microphone", iframeAllowFullscreen: true);
PullToRefreshController? pullToRefreshController; String url = ""; double progress = 0; final urlController = TextEditingController();
@override void initState() { pullToRefreshController = kIsWeb ? null : PullToRefreshController( settings: PullToRefreshSettings( color: Colors.blue, ), onRefresh: () async { if (defaultTargetPlatform == TargetPlatform.android) { webViewController?.reload(); } else if (defaultTargetPlatform == TargetPlatform.iOS) { webViewController?.loadUrl( urlRequest: URLRequest(url: await webViewController?.getUrl())); } }, ); super.initState(); }
@override Widget build(BuildContext context) { return Scaffold( body: SafeArea( child: InAppWebView( initialUrlRequest: URLRequest(url: WebUri("")),
initialSettings: settings,
pullToRefreshController: pullToRefreshController,
onWebViewCreated: (controller) async {
webViewController = controller;
setState(() {});
} }
