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.
