flutter packages get command gives an error error - flutter

Question

hello I tried running flutter pub get and I was faced with this error:
flutter pub get
Waiting for another flutter command to release the startup lock...
Running "flutter pub get" in Deutsche-Flutter...
Because every version of flutter_test from sdk depends on test_api 0.3.0 and mockito 4.1.4 depends on test_api ^0.2.19-nullsafety, flutter_test from sdk is incompatible with mockito 4.1.4.
And because no versions of mockito match >4.1.4 <5.0.0, flutter_test from sdk is incompatible with mockito ^4.1.4.
So, because deutsche depends on both mockito ^4.1.4 and flutter_test any from sdk, version solving failed.
pub get failed (1; So, because deutsche depends on both mockito ^4.1.4 and flutter_test any from sdk, version solving failed.)
exit code 1
I already ran flutter upgrade and tried to run flutter pub get here are my dependencies:
environment:
sdk: ">=2.7.0 <3.0.0"

Answer 1

Update all of your plugins and that will work. And do make sure that all of them are null-safety enabled.

Answer 2

try replacing mokito version as any as follows.
mockito: any
then check the pubspeck.lock file and search mokito and take that version number from there and replace it in pubspec.yaml file

Answer 3

update the mockito package to => mockito: ^5.2.0
