Usage

First you need an API key from WeatherAPI.com, which can be acquired for free here. Then, import the library.

Next, an instance of a WeatherRequest must be created using the obtained API key.

WeatherRequest wr = WeatherRequest('YOUR_API_KEY');

Alternatively, you can also specify a language for the weather results.

WeatherRequest wr = WeatherRequest('YOUR_API_KEY', language: Language.italian);

For all the supported languages, see the Languages section.

WeatherRequest wr = WeatherRequest('YOUR_API_KEY');

String cityName = 'Parma';

SearchResults sr = await wr.getResultsByCityName(cityName);

for (LocationResultData location in sr.locations) { /* ... */ }

WeatherRequest wr = WeatherRequest('YOUR_API_KEY');

double latitude = 44.8;
