Flutter + FlutterFire version solving failed firebase_remote_config with firebase_messaging as per migration guide

Question

I have checked many questions like this but not having proper answers so posting again.

I want to use firebase_messaging and firebase_remote_config together. But It has conflicts with firebase_core

Working Perfect When:

firebase_core: ^0.5.0+1
firebase_messaging: ^7.0.3

Problem Occurs When I add firebase_remote_config :

firebase_remote_config: ^0.6.0

Getting Error:

Because firebase_remote_config >=0.6.0 depends on firebase_core ^0.7.0 and flutter_app depends on firebase_core ^0.5.0+1, firebase_remote_config >=0.6.0 is forbidden. So, because flutter_app depends on firebase_remote_config ^0.6.0, version solving failed.

and If I change the version of the firebase_core to the latest, It's giving me the same error for firebase_messaging

I had given versions same as migration guide but not working.

Can anyone help, please?

It's basically a problem with firebase_messaging . It should depend on the newest core package, but it does not (for some mysterious reason). To get the newest info on this, follow https://github.com/FirebaseExtended/flutterfire/issues/4650 cause the situation may develop dynamically, but as of 5.02.2021, working solution is to upgrade firebase_messaging to ^8.0.0-dev.14 version. It's not stable, so we shouldn't be really happy with that, but we have no other option right now.
