Desk360flutter from git is forbidden

[DineshIT]

I'm using the Desk360 Flutter library in my application, I'm getting the following error while executing the flutter pub get command

_The current Dart SDK version is 3.0.1.

Because every version of desk360flutter from git depends on event_bus 1.1.0 which doesn't support null safety, desk360flutter from git is forbidden.
So, because evflutter depends on desk360flutter from git, version solving failed.

The lower bound of "sdk: '>=2.0.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.
For details, see https://dart.dev/null-safety'_

is there any solution for this?
