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!

Starting from version 6.0.0-beta.29, there is a breaking change about Android package name.
That’s the Changelog:

• Android package name has been changed to com.pichillilorenzo.flutter_inappwebview_android. References to old package name com.pichillilorenzo.flutter_inappwebview should be updated, for example inside AndroidManifest.xml file: <provider android:name="com.pichillilorenzo.flutter_inappwebview_android.InAppWebViewFileProvider" android:authorities="${applicationId}.flutter_inappwebview_android.fileprovider" ...

This works for me.
New Version 6.0.0 and above.

Just change the below code in AndroidManifest.xml

OLD

<provider android:name="com.pichillilorenzo.flutter_inappwebview.InAppWebViewFileProvider" android:authorities="${applicationId}.flutter_inappwebview.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" /> </provider>

NEW

<provider android:name="com.pichillilorenzo.flutter_inappwebview_android.InAppWebViewFileProvider" android:authorities="${applicationId}.flutter_inappwebview_android.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" /> </provider>
