pub get fails after upgrading flutter version for app developed with previous flutter version

I used to work with the previous stable version of flutter and mainly I used Hive DB to store data locally. I switched to a new machine and currently I have the latest version of flutter downloaded. Currently I am facing problem when I run to get packages. Below is the error

Running "flutter pub get" in myapp_flutter...                    
Because dartx >=0.2.0 <0.5.0 depends on collection >=1.14.11 <1.15.0 and every version of flutter_test from sdk depends on collection 1.15.0-nullsafety.3, dartx >=0.2.0 <0.5.0 is incompatible with flutter_test from sdk.

So, because myapp_mobile depends on both flutter_test any from sdk and dartx ^0.3.0, version solving failed.
pub get failed (1; So, because myapp_mobile depends on both flutter_test any from sdk and dartx ^0.3.0, version solving failed.)
exit code 1

Below is my dependencies mentioned on pubspec.yml

dependency_overrides:
  path: ^1.6.4
  dartx: ^0.5.0
