Because todoe depends on both lit_firebase_auth ^0.3.0 and in_app_purchase ^0.5.1, version solving failed.

[Foudas]

Hello,
The import of Flutter's package in_app_purchase in combination with lit_firebase_auth is not currently possible. When I try to "pub get" when both dependencies are declared inside pubspec.yaml I get the following errors:

Running "flutter pub get" in <app_name> ...

Because no versions of in_app_purchase match >0.5.1 <0.6.0 and in_app_purchase 0.5.1 depends on json_annotation ^4.0.0, in_app_purchase ^0.5.1 requires json_annotation ^4.0.0.
And because lit_firebase_auth >=0.2.0 depends on freezed_annotation ^0.11.0+1 which depends on json_annotation ^3.0.0, in_app_purchase ^0.5.1 is incompatible with lit_firebase_auth >=0.2.0.
So, because <app_name> depends on both lit_firebase_auth ^0.3.0 and in_app_purchase ^0.5.1, version solving failed.
pub get failed (1; So, because <app_name> depends on both lit_firebase_auth ^0.3.0 and in_app_purchase ^0.5.1, version solving failed.)
Process finished with exit code 1

How can this issue be resolved?
Happy Fluttering!
