Flutter天气管理插件weather_manager的使用

Weather Manager Package

一个使用OpenWeather API获取当前及未来天气数据的Dart包。

特性

• 可以通过纬度和经度获取当前天气数据。
• 可以获取最多5天内的每小时天气预报。

安装

在你的pubspec.yaml文件中添加以下依赖：

dependencies:
  weather_manager: ^1.0.0

然后运行flutter pub get来安装该包。

使用

导入包

import 'package:weather_manager/weather_manager.dart';

初始化WeatherMan

创建一个带有OpenWeather API密钥的WeatherMan实例：

void main() async {
  WeatherMan weatherMan = WeatherMan(apiKey: 'your_api_key_here');

  // 获取每3小时一次的5天内每小时的天气预报
  final hourlyWeatherForecast = await weatherMan.getHourlyForecast(lat: 26.9287, long: 80.9335);

  // 获取当前天气预报
  final currentWeather = await weatherMan.getCurrentWeatherByLatLong(lat: 26.9287, long: 80.9335);

  print(hourlyWeatherForecast);
  print(currentWeather);
}

示例

下面是一个完整的示例，演示如何使用WeatherMan类来获取天气数据：

import 'package:weather_manager/weather_manager.dart';

void main() async {
  // 创建一个带有API密钥的WeatherMan实例
  WeatherMan weatherMan = WeatherMan(apiKey: 'YOUR_API_KEY');

  try {
    // 获取每3小时一次的5天内每小时的天气预报
    final hourlyWeatherForecast = await weatherMan.getHourlyForecast(
      lat: 26.9287,
      long: 80.9335,
    );

    // 打印每小时天气预报详情
    print('每小时天气预报（5天）:');
    print('城市: ${hourlyWeatherForecast.cityName}, ${hourlyWeatherForecast.countryCode}');
    print('坐标: ${hourlyWeatherForecast.coordinates}');
    print('时区偏移: ${hourlyWeatherForecast.timezoneOffset}');
    print('日出时间: ${hourlyWeatherForecast.sunrise}');
    print('日落时间: ${hourlyWeatherForecast.sunset}');
    print('数据点数量: ${hourlyWeatherForecast.dataCount}');
    for (var weatherData in hourlyWeatherForecast.weatherData) {
      print('日期时间: ${weatherData.currentTime}');
      print('温度: ${weatherData.temperature}');
      print('体感温度: ${weatherData.feelsLike}');
      print('最低温度: ${weatherData.minimumTemperature}');
      print('最高温度: ${weatherData.maximumTemperature}');
      print('湿度: ${weatherData.humidity}');
      print('天气状况: ${weatherData.weatherCondition}');
      print('天气描述: ${weatherData.weatherDescription}');
      print('风速: ${weatherData.windSpeed}');
      print('云量: ${weatherData.cloudCover}');
      print('能见度: ${weatherData.visibility}');
      print('-----------------------------------');
    }

    // 获取当前天气预报
    final currentWeather = await weatherMan.getCurrentWeatherByLatLong(
      lat: 26.9287,
      long: 80.9335,
    );

    // 打印当前天气详情
    print('当前天气:');
    print('城市: ${currentWeather.cityName}, ${currentWeather.countryCode}');
    print('坐标: ${currentWeather.coordinates}');
    print('温度: ${currentWeather.weatherData.temperature}');
    print('体感温度: ${currentWeather.weatherData.feelsLike}');
    print('最低温度: ${currentWeather.weatherData.minimumTemperature}');
    print('最高温度: ${currentWeather.weatherData.maximumTemperature}');
    print('湿度: ${currentWeather.weatherData.humidity}');
    print('天气描述: ${currentWeather.weatherData.weatherDescription}');
    print('风速: ${currentWeather.weatherData.windSpeed}');
    print('云量: ${currentWeather.weatherData.cloudCover}');
    print('能见度: ${currentWeather.weatherData.visibility}');
    print('日出时间: ${currentWeather.sunrise}');
    print('日落时间: ${currentWeather.sunset}');
    print('时区偏移: ${currentWeather.timezoneOffset}');
  } catch (e) {
    print('错误: $e');
  }
}
