Flutter机场信息获取插件airport的使用

插件介绍

airport 是一个用于查询全球机场信息的 Flutter 包。通过此插件,您可以轻松获取机场的相关详细信息。


使用方法

1. 添加依赖

在您的 pubspec.yaml 文件中添加以下依赖:

dependencies:
  airport: ^版本号

然后运行以下命令以安装依赖:

flutter pub get

2. 导入插件

在需要使用的 Dart 文件中导入 airport 包:

import 'package:airport/airports.dart';

3. 获取机场信息

使用 Airports.getAirport() 方法根据 ICAO 或 IATA 编码获取机场信息。以下是一个完整的示例代码:

import 'package:flutter/material.dart';
import 'package:airport/airports.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: AirportInfoPage(),
    );
  }
}

class AirportInfoPage extends StatefulWidget {
  @override
  _AirportInfoPageState createState() => _AirportInfoPageState();
}

class _AirportInfoPageState extends State<AirportInfoPage> {
  String airportCode = "SBSP"; // 示例机场代码(圣保罗瓜鲁斯国际机场)
  Airport? airportData;

  Future<void> fetchAirportData() async {
    try {
      airportData = await Airports.getAirport(airportCode);

      if (airportData != null) {
        print("国家: ${airportData!.country}");
        print("城市: ${airportData!.city}");
        print("机场名称: ${airportData!.name}");
        print("海拔高度: ${airportData!.elevation} 米");
        print("ICAO代码: ${airportData!.icao}");
        print("纬度: ${airportData!.lat}");
        print("经度: ${airportData!.lon}");
        print("州/省: ${airportData!.state}");
      } else {
        print("未找到机场信息");
      }
    } catch (e) {
      print("发生错误: $e");
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("机场信息获取"),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ElevatedButton(
              onPressed: fetchAirportData,
              child: Text("获取机场信息"),
            ),
            SizedBox(height: 20),
            if (airportData != null)
              Text(
                "机场名称: ${airportData!.name}",
                style: TextStyle(fontSize: 18),
              ),
          ],
        ),
      ),
    );
  }
}

示例代码说明

以下是一个完整的示例代码,演示如何使用 airport 插件获取机场信息并展示到界面中:

import 'package:flutter/material.dart';
import 'package:airport/airports.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: AirportInfoPage(),
    );
  }
}

class AirportInfoPage extends StatefulWidget {
  @override
  _AirportInfoPageState createState() => _AirportInfoPageState();
}

class _AirportInfoPageState extends State<AirportInfoPage> {
  String airportCode = "SBSP"; // 示例机场代码(圣保罗瓜鲁斯国际机场)
  Airport? airportData;

  Future<void> fetchAirportData() async {
    try {
      airportData = await Airports.getAirport(airportCode);

      if (airportData != null) {
        print("国家: ${airportData!.country}");
        print("城市: ${airportData!.city}");
        print("机场名称: ${airportData!.name}");
        print("海拔高度: ${airportData!.elevation} 米");
        print("ICAO代码: ${airportData!.icao}");
        print("纬度: ${airportData!.lat}");
        print("经度: ${airportData!.lon}");
        print("州/省: ${airportData!.state}");
      } else {
        print("未找到机场信息");
      }
    } catch (e) {
      print("发生错误: $e");
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("机场信息获取"),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ElevatedButton(
              onPressed: fetchAirportData,
              child: Text("获取机场信息"),
            ),
            SizedBox(height: 20),
            if (airportData != null)
              Text(
                "机场名称: ${airportData!.name}",
                style: TextStyle(fontSize: 18),
              ),
          ],
        ),
      ),
    );
  }
}

输出示例

当您点击按钮时,程序将获取机场信息并打印到控制台。例如,对于圣保罗瓜鲁斯国际机场 (SBSP),输出可能如下:

国家: Brazil
城市: São Paulo
机场名称: São Paulo-Guarulhos International Airport
海拔高度: 760 
ICAO代码: SBSP
纬度: -23.4315
经度: -46.4983
州/省: São Paulo

在Flutter中,airport 插件是一个用于获取机场信息的工具。它可以帮助你获取机场的详细信息,如机场代码、名称、位置等。以下是如何使用 airport 插件的基本步骤:

1. 添加依赖

首先,你需要在 pubspec.yaml 文件中添加 airport 插件的依赖:

dependencies:
  flutter:
    sdk: flutter
  airport: ^1.0.0  # 请使用最新版本

然后运行 flutter pub get 来安装依赖。

2. 导入插件

在你的 Dart 文件中导入 airport 插件:

import 'package:airport/airport.dart';

3. 使用插件

你可以使用 Airport 类来获取机场信息。以下是一些常见的用法:

获取所有机场信息

void getAllAirports() async {
  List<Airport> airports = await Airport.getAllAirports();
  for (var airport in airports) {
    print('Code: ${airport.code}, Name: ${airport.name}, City: ${airport.city}, Country: ${airport.country}');
  }
}

根据机场代码获取机场信息

void getAirportByCode(String code) async {
  Airport? airport = await Airport.getAirportByCode(code);
  if (airport != null) {
    print('Code: ${airport.code}, Name: ${airport.name}, City: ${airport.city}, Country: ${airport.country}');
  } else {
    print('Airport not found');
  }
}

根据城市名称获取机场信息

void getAirportsByCity(String city) async {
  List<Airport> airports = await Airport.getAirportsByCity(city);
  for (var airport in airports) {
    print('Code: ${airport.code}, Name: ${airport.name}, City: ${airport.city}, Country: ${airport.country}');
  }
}

4. 示例代码

以下是一个完整的示例代码,展示如何使用 airport 插件获取并显示机场信息:

import 'package:flutter/material.dart';
import 'package:airport/airport.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: AirportInfoScreen(),
    );
  }
}

class AirportInfoScreen extends StatefulWidget {
  [@override](/user/override)
  _AirportInfoScreenState createState() => _AirportInfoScreenState();
}

class _AirportInfoScreenState extends State<AirportInfoScreen> {
  List<Airport> airports = [];

  [@override](/user/override)
  void initState() {
    super.initState();
    fetchAirports();
  }

  void fetchAirports() async {
    List<Airport> fetchedAirports = await Airport.getAllAirports();
    setState(() {
      airports = fetchedAirports;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Airport Information'),
      ),
      body: ListView.builder(
        itemCount: airports.length,
        itemBuilder: (context, index) {
          var airport = airports[index];
          return ListTile(
            title: Text(airport.name),
            subtitle: Text('${airport.city}, ${airport.country}'),
            trailing: Text(airport.code),
          );
        },
      ),
    );
  }
}
