Open Source Dart Weather Software

Rain is a weather forecasting application built with Flutter that combines detailed meteorological information with a customizable Material You interface. It provides current weather conditions, hourly predictions, and forecasts extending up to 12 days. Users can examine temperature, precipitation, and other weather metrics while accessing cached information without an active connection. The application includes air quality monitoring with pollutant breakdowns and support for European and US air quality indexes. Interactive OpenStreetMap maps display saved locations and weather markers, while city management tools allow users to organize unlimited locations. Scheduled notifications and Android home screen widgets provide convenient access to weather updates. Rain also supports 38 languages, multiple measurement units, customizable themes, and different time formats for a personalized forecasting experience.
