I'm working on a Flutter project that I upgraded all its packages recently,

I did flutter upgrade to Flutter 2, and then all classes got errors because of the Null Safety changes.

I fixed as many classes as I could (almost all of them).

But I still get some errors in the logcat.

So I need someone experienced with the Null Safety Migration to..

- fix all issues until there's no more.

- fix issues related with push notifications when the songs are playing in the background (iOS & Android).. I'm using package named "audio_service-0.17.0"

Please start your proposal with "Null Safety Expert" to distinguish real proposals from automated ones.
