How to resolve version solving failed in flutter

Question

Because flutter_bloc: 0.21.0 depends on provider: ^3.0.0 and no versions of flutter_bloc match: >0.21.0 <0.22.0, flutter_bloc: ^0.21.0 requires provider: ^3.0.0. So, because it tells_me that it depends on both provider: ^4.1.2 and flutter_bloc: ^0.21.0, version solving failed.

pub get failed (1; So, because tellz_me depends on both provider ^4.1.2 and flutter_bloc ^0.21.0, version solving failed.)

update your flutter_bloc: ^4.0.0 and all the packages as per latest version — Sanjeev Sangral, Jun 09 '20 at 05:54
Then i get this :- Because tellz_me depends on image_collage_widget ^1.0.0 which depends on flutter_bloc ^0.21.0, flutter_bloc ^0.21.0 is required. So, because tellz_me depends on flutter_bloc ^4.0.0, version solving failed. pub upgrade failed (1; So, because tellz_me depends on flutter_bloc ^4.0.0, version solving failed.) — Tarun Mehta, Jun 09 '20 at 05:57
what package is that ** tellz_me** ? can you share the link? — Sanjeev Sangral, Jun 09 '20 at 18:47

you need to use dependency override.

this code is from my project, so path provider was the problem, you need to find the package that makes. the conflict and put it inside the dependency_overrides this will fix your problem.

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^1.0.0
  file_picker: ^3.0.0
  hive: ^2.0.0
  hive_flutter: ^1.0.0

dependency_overrides:
  path_provider: 2.0.1

See this: https://stackoverflow.com/a/67517680/13500457

And how to update the dependencies automatically:

I would suggest you to remove all dependencies and run pub get and add the dependencies using the command method, not by copy pasting. See this or mentioned above:

I hope it helps, happy coding!
