Error when running flutter pub get command

I would like to ask for help, I've searched all the answers here in the community and I can't solve my error.
I had to update a personal project to Android sdk 32, but when I try to run the Flutter pub get command I'm having an SDK version error, I'm leaving the pub spec and the error image below.

replace your sdk with

I managed to solve this problem, I uninstalled flutter on the mac and installed it again, I think the mac was cached.

I think the problem is in the firabase_auth package. I've searched a lot but couldn't find how to fix the problem.
What is the problem? How can I solve it? Thanks in advance for the help.
#MuhammadJunaidKhalid When I upgrade the firebase_auth version to the latest version, I get this output:
Because no versions of global_configuration match >1.6.0 <2.0.0 and global_configuration 1.6.0 depends on http ^0.12.2, global_configuration ^1.6.0 requires http ^0.12.2.

flutter starting error: version solving failed

I have downloaded a flutter project and placed the lib, assets and pubsec.yaml files in a new project. After "flutter packages get" There are more than 1k+ error. this the error:

Just remove the version in dependency which creates problem and it will work

i want to add fonts in flutter app, but there is a problem in pubspec.yaml

so, you have an indentation issue in the fonts sections. Do this instead:

fonts:

fonts:
- asset: fonts/Pacifico-Regular.ttf
For reference, check this page: https://flutter.dev/docs/cookbook/design/fonts

I think You have an Error of indentation of which means your fonts are not at the correct position, see mine below code.
fonts:
- family: GraphikWide
fonts:
- asset: fonts/Graphik-Wide-Regular.otf
- asset: fonts/Graphik-Wide-Medium.otf
weight: 400
- family: Gibson
fonts:
- asset: fonts/gibson-regular.ttf
- asset: fonts/gibson-semibold.ttf
weight: 400
- asset: fonts/gibson-light.ttf
weight: 100
just replace your full font code in pubspec with my code then do the changes

flutter test from sdk is forbidden

I downloaded project from github and tried to run the project but it requires Get Dependencies and when I press Pub Get to for dependencies I receive the following error:
Because every version of flutter_test from sdk depends on path 1.7.0 and fstore depends on
path 1.6.4, flutter_test from sdk is forbidden.
So, because fstore depends on flutter_test any from sdk, version solving failed.

I tried already flutter upgrade but it did not work, is there any solution for this problem because

I have found the solution to this problem, you can use both versions of the path dependency through override_dependency, which will satisfy the requirnments.
Try Following solution:
dependencies:
flutter:
sdk: flutter
dio: ^3.0.9
hive_flutter: ^0.3.0+2
hive: ^1.4.1+1
path: ^1.7.0
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.3
dependency_overrides:
path: ^1.6.4
dev_dependencies:
flutter_test:
sdk: flutter
hive_generator: ^0.7.0+2
build_runner: ^1.10.0

You can also just simply replace 1.7.0 with 1.6.4 as the error says.
