SMHI Open Data for Dart #

This package is in early development and some features may not work as intended. If so, feel free to submit a pull request.

A Dart package for usage of the Swedish Meteorological and Hydrological Institute's Open Data API. The API allows you to get the weather and other meterological data like air temperature & pressure. At the time of writing this, the Meteorological Forecasts API is available in the following countries:

  • Sweden
  • Norway
  • Finland
  • Denmark
  • Estonia

And partly:

  • Latvia
  • Lithuania

Usage #

This example shows how to get the air temperature at this time tomorrow in Stockholm:

import 'package:smhi/smhi.dart';

final MeteorologicalForecasts meteorologicalForecasts = MeteorologicalForecasts();
// Your request will automatically be cached. So if you make the same request again, it will return the cached version.
final Forecast? forecast = await meteorologicalForecasts.forecast(const GeoPoint(59.334591, 18.063240));
if (forecast != null) {
	// Forecasts are divided into moments where each moment represents a date & time.
	// Read more at SMHI's documentation: https://opendata.smhi.se/apidocs/metfcst/get-forecast.html
	final ForecastMoment moment = forecast.momentWhen(DateTime.now().add(const Duration(days: 1)));
	print(moment.valueOf(MetFcstParameter.airTemperature));
}
