How to make a database transaction with Room using functions from differents DAOs and using coroutines?

Question

I want to make a database transaction with Room using functions from different Daos using coroutines.

If I use @Transaction annotation I can only use the functions from the same DAO. If I use the Room database function runInTransaction I can't use coroutines.

Is there a way to achieve this?

There is a suspend extension function for this withTransaction(). Check this out:
