getData static method

Future<GeoData?> getData({ String? ip, String? lang, List<String> fields = const [], String? apiKey, })

Get geo data from IP-API.com.

To query a different than the current IP, specify it using ip. API response is provided in English unless a different language is specified using lang. To receive only specific fields from the API specify them using fields. Finally, if IP-API.com's pro version should be used, specify a valid API key using apiKey. Note that the free version uses HTTP while the pro version uses HTTPS.

Implementation

static Future<GeoData?> getData({
  String? ip,
  String? lang,
  List<String> fields = const [],
  String? apiKey,
}) async =>
    get(Uri(
      scheme: apiKey != null ? 'https' : 'http',
      host: apiKey != null ? 'pro.ip-api.com' : "ip-api.com",
      path: '/json/${ip ?? ''}',
      queryParameters: {
        if (apiKey != null) 'key': apiKey,
        if (lang != null) 'lang': lang,
        if (fields.isNotEmpty) 'fields': fields.join(',')
      },
    )).then((response) => response.statusCode == 200
        ? GeoData.fromJson(jsonDecode(response.body)
          ..putIfAbsent('query', () => ip)
          ..addAll({
            'lang': lang,
          }))
        : null);
