Update dependencies

[alperenekin]

In the newer Flutter versions(3.19 in my case), it is not possible to build the app due to File dependency.

If need be this can also be file: >=6.0.0 <8.0.0. But please support the newest flutter versions!

This fixes:

• Update file dependency to 7.0.0 #128

@alperenekin Im curious, why updating pub_updater is important?

[alperenekin]

@danielgomezrico

Because pub_updater <0.4.0 depends on process ^4.2.3 which depends on file ^6.0.0, pub_updater <0.4.0 requires file ^6.0.0.
So, because dart_code_linter depends on both file ^7.0.0 and pub_updater ^0.3.0, version solving failed

I updated the PR as it is suggested by @bvoq. Using a range seems to work fine, since it is actually comptabile with the older version.
