Kotlin and Android Development featuring Jetpack

Add Converters to the Database

Inside the data package, add a new class called Converters. This class will contain eight functions corresponding to four sets of conversions: OffsetDateTime to/from String, GameState to/from Int, List<Int> to/from String, and AI to Int.

The OffsetDateTime converter functions, used with the startTime and endTime properties inside the Game class, translate OffsetDateTime objects to and from a formatted string using a DateTimeFormatter object. You’re welcome to use any logical date/time format here; I’m using DateTimeFormatter.ISO_OFFSET_DATE_TIME since it has all the information we need and is a standardized format. For reference, date/time text in this format will look like 2014-01-24T15:45:05.023Z.
