condition_aggregator 0.0.4

Source-neutral interface for severity-qualified meteorological-advisory aggregation. Defines Advisory event + AdvisoryProvider for per-source adapters. Pure Dart.

example/main.dart

// Minimal example for condition_aggregator.
//
// Demonstrates the source-neutral Advisory typed event the umbrella
// interface defines. Per-source adapter packages
// (`condition_aggregator_jma`, `condition_aggregator_nws`,
// `condition_aggregator_owm_road_risk`) implement `AdvisoryProvider`
// and produce these typed events; consumers receive a single typed
// shape across publishers.
