Issue occurs on: Windows, MacOS
Plugin name: package_info_plus_windows
Plugin version: 0.2.0

Steps to Reproduce

1. Add package_info_plus 0.6.4 to dependencies
2. Add path_provider 2.0.0-nullsafety.1 to dependencies
3. Run 'flutter pub get' and observe version resolution failure.
4. Override win32 dependency to version 2.0.0 will also fail due to dart compilation failure.

Logs for step 3

Because no versions of path_provider match >2.0.0-nullsafety.1 <3.0.0 and path_provider 2.0.0-nullsafety.1 depends on path_provider_windows ^0.1.0-nullsafety.3, path_provider ^2.0.0-nullsafety.1 requires path_provider_windows ^0.1.0-nullsafety.3.
And because no versions of path_provider_windows match >0.1.0-nullsafety.3 <0.2.0 and path_provider_windows 0.1.0-nullsafety.3 depends on win32 ^2.0.0-nullsafety.12, path_provider ^2.0.0-nullsafety.1 requires win32 ^2.0.0-nullsafety.12.
And because package_info_plus_windows 0.2.0 depends on win32 ^1.7.3 and no versions of package_info_plus_windows match >0.2.0 <0.3.0, path_provider ^2.0.0-nullsafety.1 is incompatible with package_info_plus_windows ^0.2.0.
And because package_info_plus 0.6.4 depends on package_info_plus_windows ^0.2.0 and no versions of package_info_plus match >0.6.4 <0.7.0, path_provider ^2.0.0-nullsafety.1 is incompatible with package_info_plus ^0.6.4.
So, because xxxxxx depends on both package_info_plus ^0.6.4 and path_provider ^2.0.0-nullsafety.1, version solving failed.

Hi, the win32 & ffi update has been done (#155) but null-safety migration is still in progress (#154). If you want or need the update right away, perhaps you can use package_info_plus straight from Git until the null-safe version is out?

Dependencies have been upgraded in https://pub.dev/packages/package_info_plus/versions/1.0.0-nullsafety.1
