Compatibility issue with get_it 8.0.0

[Konst80]

Hello everyone,

during the installation via "flutter pub add injectable" I get the following error:

The current Dart SDK version is 3.5.3.

Because injectable <1.2.0-nullsafety doesn't support null safety and injectable >=1.2.0-nullsafety <1.4.0 depends on get_it ^6.0.0, injectable <1.4.0 requires get_it ^6.0.0.
And because injectable >=1.4.0 <1.5.3 depends on get_it ^7.0.0 and injectable >=1.5.3 depends on get_it ^7.2.0, every version of injectable requires get_it ^6.0.0 or >=7.0.0
  <8.0.0.
So, because testapp depends on both get_it ^8.0.0 and injectable any, version solving failed.

The lower bound of "sdk: '>=2.5.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.

My understanding is that this is related to get_it ^8.0.0, which is quite recent.
