serialize method

  1. @override
String? serialize(
  1. DartType targetType,
  2. String expression,
  3. TypeHelperContext context
)
override

Returns Dart code that serializes an expression representing a Dart object of type targetType.

If targetType is not supported, returns null.

Let's say you want to serialize a class Foo as just its id property of type int.

Treating expression as a opaque Dart expression, the serialize implementation could be a simple as:

String serialize(DartType targetType, String expression) =>
  "$expression.id";
```.

Implementation

@override
String? serialize(
  DartType targetType,
  String expression,
  TypeHelperContext context,
) {
  if (!_matchesType(targetType)) {
    return null;
  }

  final buffer = StringBuffer(expression);

  if (targetType.isNullableType) {
    buffer.write('?');
  }

  buffer.write('.inMicroseconds');

  return buffer.toString();
}
