Flutter dependencies are deprecated in iOS - firebase

Question

I know many Flutter developers use lots of different packages in their applications. Nowadays, I'm trying to build a final version of my app in iOS but it gives me headache. I'm using packages such as image_picker, flutter_local_notifications, flutter_inappwebview, firebase_messaging etc. Due to compatibility issue on Firebase libraries, I need to target min. iOS 10.0.
These are the versions of some libraries that give errors when building to iOS on Simulator.
image_picker: ^0.6.7+22
flutter_local_notifications: ^4.0.1
flutter_inappwebview: ^4.0.0+4
# Only Firebase_messaging gives errors between Firebase libraries but
# I would like to show you the versions of all of them
firebase_admob: ^0.11.0+1
firebase_messaging:
firebase_core: ^0.7.0
firebase_auth: ^0.20.0+1
cloud_firestore: ^0.16.0
A little part of warnings related to firebase_messaging

And there are these kind of deprecated methods, deprecated UI elements errors in warning output. When I target min. iOS 9.0, this time GoogleMobilAds, FirebaseInstanceID, flutter_inappwebview-4.0.0+4 etc. give errors.
So I can't avoid errors and warnings when building for iOS no matter what platform I'm targeting. Any idea how to solve the long paragraphs of error messages due to deprecated stuff?
Edit: I'm adding output of flutter doctor -v

Upgrading to new Flutter version solved my problem. If anyone see this, consider upgrading your dependencies and Flutter.
