IPApi Dart

A lightweight Dart package for retrieving IP address information using the IPQuery.io API service.

Features

• Retrieve detailed information about any IP address
• Get your own IP address
• Access location data (country, city, coordinates)
• Access ISP/network information
• Get risk assessment data (VPN detection, proxy detection, Tor exit node detection)
• Simple API with Future-based calls
• Built with Dio for efficient HTTP requests

Installation

Add this package to your pubspec.yaml:

dependencies:
  ipapi_dart: ^0.0.1

Then run:

dart pub get

Usage

Import the package

import 'package:ipapi_dart/ipapi_dart.dart';

Getting your own IP address

String myIp = await IPInfo.QueryOwnIP();
print('My IP address is: $myIp');

Getting information about a specific IP

IpInfoModel ipInfo = await IPInfo.queryIP('1.1.1.1');

// Access information from the model
print('IP: ${ipInfo.ip}');
print('Country: ${ipInfo.location.country}');
print('City: ${ipInfo.location.city}');
print('ISP: ${ipInfo.isp.isp}');

Complete example

import 'package:ipapi_dart/ipapi_dart.dart';

void main() async {
  try {
    // Get your own IP
    String myIp = await IPInfo.QueryOwnIP();
    print('My IP address is: $myIp');
    
    // Query information about a specific IP
    IpInfoModel cloudflareInfo = await IPInfo.queryIP('1.1.1.1');
    
    // Print location information
    print('Country: ${cloudflareInfo.location.country} (${cloudflareInfo.location.countryCode})');
    print('City: ${cloudflareInfo.location.city}, ${cloudflareInfo.location.state}');
    print('Coordinates: ${cloudflareInfo.location.latitude}, ${cloudflareInfo.location.longitude}');
    
    // Print risk assessment
    print('VPN: ${cloudflareInfo.risk.isVpn ? 'Yes' : 'No'}');
    print('Proxy: ${cloudflareInfo.risk.isProxy ? 'Yes' : 'No'}');
    print('Risk Score: ${cloudflareInfo.risk.riskScore}/10');
  } catch (e) {
    print('Error: $e');
  }
}

API Response Model

The API returns data in the following structure:

{
  "ip": "1.1.1.1",
  "isp": {
    "asn": "AS13335",
    "org": "Cloudflare, Inc.",
    "isp": "Cloudflare, Inc."
  },
  "location": {
    "country": "United States",
    "country_code": "US",
    "city": "Los Angeles",
    "state": "California",
    "zipcode": "90001",
    "latitude": 34.0522,
    "longitude": -118.2437,
    "timezone": "America/Los_Angeles",
    "localtime": "2025-03-20T21:25:31"
  },
  "risk": {
    "is_mobile": false,
    "is_vpn": false,
    "is_tor": false,
    "is_proxy": false,
    "is_datacenter": true,
    "risk_score": 1
  }
}

Model Structure

IpInfoModel

Main class that contains all IP information:

class IpInfoModel {
  final String ip;
  final ISPInfoModel isp;
  final LocationInfoModel location;
  final RiskInfoModel risk;
  
  // Constructor and fromMap methods
}

LocationInfo

Contains geographical information:

class LocationInfoModel {
  final String country;
  final String country_code;
  final String city;
  final String state;
  final String zipcode;
  final double latitude;
  final double longitude;
  final String timezone;
  final String localtime;
  
  // Constructor and fromMap methods
}

IspInfo

Contains network provider information:

class ISPInfoModel {
  final String asn;
  final String org;
  final String isp;
  
  // Constructor and fromMap methods
}

RiskInfo

Contains security and risk information:

class RiskInfoModel {
  final bool is_mobile;
  final bool is_vpn;
  final bool is_tor;
  final bool is_proxy;
  final bool isDatacenter;
  final int risk_score;
  
  // Constructor and fromMap methods
}

Error Handling

The package throws exceptions when API calls fail. Always wrap API calls in try-catch blocks:

try {
  IpInfoModel ipInfo = await IPInfo.queryIP('1.1.1.1');
  // Process data
} catch (e) {
  // Handle error
  print('Error: $e');
}

API Limits

This package uses the IPQuery.io service, which may have rate limits or require an API key for extended usage. Please check their website for the latest information on usage limits.
