Flutter Upgrade Issue

Question

I upgraded my flutter to 2.2.0. But is showing an error like this:

Because mockito >=5.0.8 depends on code_builder ^4.0.0 and build_runner >=0.9.1+1 <2.0.0 depends on code_builder >2.3.0 <4.0.0, mockito >=5.0.8 is incompatible with build_runner >=0.9.1+1 <2.0.0. So, because cost_of_care depends on both build_runner ^1.11.0 and mockito ^5.0.8, version solving failed. pub get failed (1; So, because cost_of_care depends on both build_runner ^1.11.0 and mockito ^5.0.8, version solving failed.) Exited (1)

Please tell me what is this error and how I can fix it. I already upgraded all my dependencies to the latest.

This is my pubspec.yaml

Answer 1

The error seems to be quite clear.

Your latest version of mockito needs the higher version of code_builder but your build_runner version is too low to support it.

There is a later version of build_runner available, which is build_runner: ^2.0.3 which supports code_builder: ^4.0.0.

So, in your pubsec.yaml, just change your build_runner version to ^2.0.3 wherever you have it.

That should be fixing it.

This is a dependency issues, one by one check errors and change the library version for example enter link description here version

flutter pub get
#check error
#replace that library with higher or lower version accordingly
#After update
flutter pub get
