import 'package:dart_json_mapper/dart_json_mapper.dart' show JsonMapper, jsonSerializable;
import 'package:dart_json_mapper_fixnum/dart_json_mapper_fixnum.dart' show fixnumAdapter;
import 'main.mapper.g.dart' show initializeJsonMapper;
@jsonSerializable
class FixnumClass {
Int32 integer32;
FixnumClass(this.integer32);
}
void main() {
initializeJsonMapper(adapters: [fixnumAdapter]);
print(JsonMapper.serialize(
FixnumClass(Int32(1234567890))
