iOS example fails getting dispatcherKey and setting data. Also missing background update function on iOS

[large]

What happened?

Compiled the packages/home_widget/example/ios with failure because of missing Flutter package:

Swift Compiler Error (Xcode): Unable to find module dependency: 'Flutter'

Had to add the flutter package like this, to get it running: https://stackoverflow.com/questions/79785796/swift-compiler-error-xcode-unable-to-find-module-dependency-flutter

When running the example text is shown (but no send receive is detected by the widget).

Also getting an assert on: https://github.com/ABausG/home_widget/blob/28f8e8400fc9a46a7cbf58e143c9d005f0d4b52e/packages/home_widget/ios/Classes/HomeWidgetBackgroundWorker.swift#L40-L42

The dispatcher is never found

What do you expect?

Work as good as the Android version

Relevant log output

-- LLDB integration loaded --
`UIScene` lifecycle will soon be required. Failure to adopt will result in an assert in the future.

iOS

Other information

I have adopted an early version of your home_widget and it works (most of the time). Now I am looking to update it, but is iOS falling behind?

Are you interested in working on a PR for this?
