But, if you anticipate multiple values from the provider, you should likely be using a `StreamProvider`. /// Extending ValueNotifier would be another simple way to do this. - Caballep/flutter-provider-routing flutter, path_provider_linux, path_provider_macos, path_provider_platform_interface, path_provider_windows. // Simplest way to retrieve the provided value. A Flutter app that maximizes application code reuse while adheri... sample. https://pub.dev/packages/flutter_bloc Thanks to Flutter Web, I created the app (a simple, but impactful solution) in twenty days.
