TypeConverter<D, S> class
abstract
Maps a custom dart object of type D into a primitive type S understood
by the sqlite backend.
Dart currently supports DateTime, double, int, Uint8List, bool
and String for S.
Using a type converter does impact the way drift serializes data classes to JSON by default. To control that, use a JsonTypeConverter or a custom ValueSerializer.
Also see BuildGeneralColumn.map for details.
