ipstack.com IPv4 Geolocation Lookup

See more Geolocation Examples

Demonstrates how to lookup Geolocation data for an IPv4 address using the ipstack.com REST API. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  // Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
  final String jsonStr;
  try {
    jsonStr = http.quickGetStr('http://api.ipstack.com/149.250.207.170?access_key=YOUR_ACCESS_KEY');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final json = CkJsonObject();
  json.emitCompact = false;
  json.load(jsonStr);

  print(json.emit());
