Questions tagged [flutter-provider]

For questions relating to the "Provider" package for the Flutter framework. Use this tag in combination with the general [flutter] tag. If your question applies to Flutter more generally, use the [flutter] tag only.

This tag should be used for any questions regarding the provider package for the framework.

Provider uses InheritedWidget's to provide dependency injection functionality for state management in Flutter applications.
