asNullable<D, S extends Object, J extends Object> static method

JsonTypeConverter2<D?, S?, J?> asNullable<D, S extends Object, J extends Object>(JsonTypeConverter2<D, S, J?> inner)

Wraps an inner type converter that only considers non-nullable values as a type converter that handles null values too.

The returned type converter will use the inner type converter for non- null values. Further, null is mapped to null in both directions (from Dart to SQL and vice-versa).

Implementation

static JsonTypeConverter2<D?, S?, J?>
    asNullable<D, S extends Object, J extends Object>(
        JsonTypeConverter2<D, S, J?> inner) {
  return _NullWrappingTypeConverterWithJson(inner);
}
