Covers why GlobalScope should be avoided in favor of viewModelScope, how to use Dispatchers correctly, structured concurrency with async/await, and the difference between one-time operations (suspend functions) and continuous data streams (Flow). Also explains StateFlow for UI state management, combining multiple data sources with combine(), and error handling in Flow pipelines. Ends with a recommended reactive architecture pattern: Database → Flow → ViewModel → StateFlow → UI. ## Full article daily.dev links to this article rather than hosting it.
