1.2.3. Use Resas #
In order to use the RESAS API, you need an API key issued on the official website. Generate the API key from the following site and pass it to the constructor of the Resas class.
import 'package:resas/resas.dart';

void main() async {
final resas = Resas.connectWith(
key: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx', // ← Replace with your API key.
);

// Once the instance is created, you can easily access the API by simply calling the method.
final prefecturesResponse = await resas.common.prefectures();

// It's easy to handle response status.
if (prefecturesResponse.status.isNotOk) {
// Do something when status is not OK (200).
return;
}

print(prefecturesResponse);

final citiesResponse = await resas.common.cities(
prefectureCode: prefecturesResponse.result![0].code,
);
print(citiesResponse);

final oldCitiesResponse = await resas.common.oldCities(
prefectureCode: prefecturesResponse.result![0].code,
cityCode: citiesResponse.result![0].code,
);
print(oldCitiesResponse);
}
