Forward geocoding:

void main() async {
  final api = PhotonApi();
  final results = await api.forwardSearch('munich');
}

Reverse geocoding:

import 'package:flutter_photon/flutter_photon.dart';

void main() async {
  final api = PhotonApi();
  final results = await api.reverseSearch(48.123, 11.321);

Self-hosted instances (custom URL):

void main() async {
  final api = PhotonApi(baseUrl: 'https://example.com/api');
}

You can find more examples on how to use the API by looking at the tests.
