Airport Data Dart

A comprehensive Dart library for retrieving airport information by IATA codes, ICAO codes, and various other criteria. This library provides easy access to a large dataset of airports worldwide with detailed information including coordinates, timezone, type, and external links.

Installation

Add this to your pubspec.yaml:

dependencies:
  airport_data: ^1.0.0

Then run:

dart pub get

Platform Support

Platform	Supported
Flutter Android	Yes
Flutter iOS	Yes
Flutter macOS	Yes
Flutter Windows	Yes
Flutter Linux	Yes
Flutter Web	Yes
Dart CLI / Server	Yes

On dart:io platforms (mobile, desktop, CLI), gzip decompression uses the native codec for maximum performance. On web, a pure-Dart fallback from package:archive is used automatically — no configuration needed.

Airport Data Structure

Each Airport object contains the following fields:

  iata: 'SIN',                    // 3-letter IATA code
  icao: 'WSSS',                   // 4-letter ICAO code
  time: 'Asia/Singapore',         // Timezone identifier
  utc: 8,                         // UTC offset
  countryCode: 'SG',              // 2-letter country code
  continent: 'AS',                // 2-letter continent code (AS, EU, NA, SA, AF, OC, AN)
  airport: 'Singapore Changi Airport',  // Airport name
  latitude: 1.35019,              // Latitude coordinate
  longitude: 103.994003,          // Longitude coordinate

Basic Usage

import 'package:airport_data/airport_data.dart';

// Get airport by IATA code
final airports = AirportData.getAirportByIata('SIN');
print(airports.first.airport); // "Singapore Changi Airport"

// Get airport by ICAO code
final airports = AirportData.getAirportByIcao('WSSS');
print(airports.first.countryCode); // "SG"

// Search airports by name
final airports = AirportData.searchByName('Singapore');
print(airports.length); // Multiple airports matching "Singapore"

// Find nearby airports (within 50km of coordinates)
final nearby = AirportData.findNearbyAirports(1.35019, 103.994003, 50);
print(nearby); // Airports near Singapore Changi
