As you can see from the image below, flutter is referencing the wrong versions.
Even after moving them into the override section running a flutter pub cache clean

It is because you are using caret (^)

Easily just remove ^
before each page like below and check again:
dependencies:
firebase_core: 2.4.0
firebase_messaging: 14.1.4
