flutter dependences version solving failed

I am facing this error. I really want to use both packages but I can’t figure out how to solve the next error. Can you help me?

Because u_lo_musico_v3 depends on awesome_calendar ^1.1.3 which depends on intl ^0.17.0, intl ^0.17.0 is required.
So, because u_lo_musico_v3 depends on intl ^0.18.0, version solving failed.

>Solution :

There are a few things you could do.

• Downgrade the version of intl library that you are using to version 0.17.0 as awesome_calendar is not compatible with what is in your pubspec 0.18.0.
• You could add intl ^0.17.0 under dependency overrides. Which overrides all versions of intl that whatever dependency may use and resolves it to 0.17.0
