Kotlin and Android Development featuring Jetpack: Typo in PennyDropDatabase.getDatabase() (page 125)
Typo found in PennyDropDatabase.getDatabase() on page 125: “Instance?” should be “instance?”
What’s there:
scope.launch {
-> Instance?.pennyDropDao()?.insertPlayers(
AI.basicAI.map(AI::toPlayer)
)
}
What should be there:
scope.launch {
-> instance?.pennyDropDao()?.insertPlayers(
AI.basicAI.map(AI::toPlayer)
)
}
The code in the .zip file is correct.

Thanks! I changed this a while back since there was no reason for Instance to be capitalized.
Also, just a heads up that I am seeing all your posts and am making notes of each one, so keep the updates coming (and thank you)!
