set method

Change set(V? value)

The change that sets the field to value, or makes it null, for update. Null gives a required field with a default its default.

Implementation

Change set(V? value) {
  if (path.length != 1) {
    throw invalidArgument(
      '`update` sets the fields of the object itself, not `${path.join('.')}`',
    );
  }

  return Change._(
    path.single,
    value == null ? null : (writer, _) => _write(writer, value),
  );
}
