How to downgrade packages in flutter?

cloud_firestore 0.12.11 isn't working for me in flutter, it won't allow my app to launch in debug. How would i downgrade this package? In the pubspec file I used a lower version of cloud_firestore ie. (cloud_firestore: ^0.12.9+4) and then saved and VS Code got the packages but when I try to launch again it gives the same error : 

                     ~~~~~ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When i checked the flutter SDK inside of the .pubcache -> hosted -> pub.dartlang.org -> there is a folder in there cloud_firestore 0.12.11 how do i fix this? my applicatoin starts fine when i launch with cloud_firestore commented out in the pubspec file.

If you have any packages in conflict, just put any instead of the version number at the end. Instead of flutter_hive: 1.0.0 you go like => flutter_hive: any. It will solve everything.

yeah you need to remove the caret, but you also need to clean out those old (new) folders!

in the terminal window, you need to run "$ flutter clean" in the project root, and "$ flutter pub upgrade", and possibly delete the Pods/ folder and get everything reset from scratch.

Also might need to use "file/invalidate cache" (in android studio).

cloud_firestore: ^0.12.9+4

This little sign ^ called caret is used to tell the pub to get this version or higher. To pick a specific version you need to remove it.

cloud_firestore: 0.12.9+4

To learn more about dependencies visit Dart documentation about caret syntax and version constraints.
