Ios 26 flutter app run time failure

Please don't post screenshots of errors. Post the actual text.

You can't search text in a screenshot, so if someone has this issue in future and this post has a solution, it won't come up.

Also, it look like you need to move your app to use UIScene. This has been a known migration since about iOS 13. If you need a hint on how to do this, create a new project in Xcode and you'll see how the SceneDelegate is implemented.
