Old version of build_barback prevent from using the package

[AlexandreRoba]

Hi,

I'm getting this error message. Any idea on how to resolve this?

Because every version of flutter_test from sdk depends on analyzer 0.31.2-alpha.2 and build_barback >=0.2.2 <=0.5.0+2 depends on analyzer >=0.27.1 <0.31.0, flutter_test from sdk is incompatible with build_barback >=0.2.2 <=0.5.0+2. And because every version of graphql_fetch_generator depends on build_barback ^0.4.0+2, flutter_test from sdk is incompatible with graphql_fetch_generator. So, because sweetnest_app depends on both flutter_test any from sdk and graphql_fetch_generator any, version solving failed. pub get failed (1)

Regards,
