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!

You can use my new package zikzak_inappwebview fork of this package that I will keep maintaining. Thanks @pichillilorenzo for developing/maintaining this package for a long time. I guess he is busy or on vacataion. I am the builder of Flutter Vendure (open source headless commerce framework) package. Vendure Please open your PRs here and I am happy to check them and merge them by Monday.

This is an issue with xcode 16. What worked for me was to install previous version of xcode 15.4 using xcodes and then changing command line tools version in xcode locations settings to 15.4 instead of 16 and voila, everything is back to working again 😄

Hello, folks I found a temporary solution for the issue in Xcode. In the InAppWebView class under the iOS folder, you need to replace the following code in the Java file when you encounter the error:

Replace:

public override func evaluateJavaScript(_ javaScriptString: String, completionHandler: ((Any?, Error?) -> Void)? = nil)

With:

open override func evaluateJavaScript(_ javaScriptString: String, completionHandler: (@MainActor (Any?, (any Error)?) -> Void)? = nil)

Additionally, I was facing package-related errors, so I updated the Firebase packages according to my Flutter version. Now, the app is finally running on iOS 18.

After that, I encountered a "command non-zero exit" error. The solution for this is to make changes within the Build Settings of the Runner project, as shown in the screenshot below.

Thank you.

This Not working. for me

This is an issue with xcode 16. What worked for me was to install previous version of xcode 15.4 using xcodes and then changing command line tools version in xcode locations settings to 15.4 instead of 16 and voila, everything is back to working again 😄

This worked for me, but since I upgraded MacOS to Sequoia, I had to perform these additional steps

• open a terminal
• open folder where Xcode is installed (Applications)
• drag and drop the Xcode app into the terminal
• append /Contents/MacOS/Xcode
• run the command

Released new version 6.1.0 with the fix, thanks.
