Getting Started with Slack Circuit Framework for Jetpack Compose

Slack Circuit is a lightweight architecture framework for Jetpack Compose that enforces unidirectional data flow by separating UI, state, and business logic. It introduces a Presenter layer (similar to ViewModel in MVVM) that manages state and handles events, while Composables remain simple renderers. A step-by-step counter app example demonstrates defining typed Screens, modeling events and UI state with CircuitUiState, implementing a Presenter, wiring everything in MainActivity, and keeping UI composables clean. The pattern improves testability and maintainability for medium-to-large Compose projects.
