In this block:

// before
suspend fun refreshData(){
    val response = api.getData()
    database.fruittieDao().insert(response.feed)
}

// after
suspend fun refreshData(){
    val response = api.getData()
    with(database) {
        useWriterConnection {
            it.immediateTransaction {
                fruittieDao().insert(response.feed)
            }
        }
    }
}

After wrapped in immediateTransaction, which mentioned here, data flow couldn't receive any change, neither any invalidation observer.

In pure Room without KMP, multiple DAO operations normally wrapped in database.withTransaction block. How to do in KMP?

Implicitly invalidation when a writer connection is used

Implicitly invalidation when a writer connection is used 
 
To keep behaviour consistent with existing usage of SupportSQLite via Room, when a write operation is done using the writer connection, Room should attempt to check for invalidation and refresh observers.
