When I include google maps my build fails - google-maps

Question

When I include a "google maps" dependency into pubspec.yaml
google_maps_flutter: ^0.2.0+3
my build fails with:

Can someone point me in the right direction to understand and track this down. This project built just fine previously.

Answer 1

This is because you have in your app google_maps_plugin version that is using androidx and probably your app and/or some other dependency is using android support library. I had provided some ways to solve this kind of problem here and here.
But what you need to do is migrate all your app to androidx and use updated dependencies versions that already has been migrated too.
Other way is avoid androidx making downgrade of your dependencies packages for versions pre androidx.
For more details about flutter apps androidx migration see the original docs reference
I hope it helps.
