Request From Flutter Team: Migrate AppDelegate.window API usage

[hellohuanlin]

Is there an existing feature request for this?

Operating System

iOS

Pain

This plugin currently relies on legacy UIApplication APIs to access the window (code here). With Apple's mandatory adoption of the UIScene lifecycle in iOS 27, these legacy patterns will result in unexpected behavior since AppDelegate.window would be nil.

Suggested solution

For detailed instructions, please see the official UIScene adoption guide for plugins.

This issue especially important for iOS 27 or later, since Apple is marking UIScene lifecycle is mandatory. With the current implementation relying on AppDelegate.window, the window can be nil on iOS 27. Which may cause the plugin to fail to obtain the correct UIWindow and lead to unexpected behavior at runtime.

Could you please consider prioritizing this migration and updating the iOS implementation to use the UIScene-based approach recommended by Flutter/Apple?

This will be important for apps using flutter_inappwebview when they move to the iOS 27 SDK.

Thanks

Thank you for your work on this issue.
We are currently preparing our app for iOS 27 and are reviewing the impact of the UIScene lifecycle requirement.

Could you please let us know if there is an expected release timeline or target version for flutter_inappwebview with UIScene lifecycle support?

A rough estimate would be greatly appreciated, as it would help us plan our migration shedule.
