To implement a UI state machine for multi-step navigation, apply Type 2 patterns to manage loading states, errors, and screen transitions across Android and iOS. You configure minimal Props and implement the model function to drive the presentation layer.

Type 1 patterns handle simple UI state flows confined to a single screen, while Type 2 patterns manage complex multi-step flows that include loading indicators, error handling, and multi-step navigation transitions across platforms.

You test UI navigation and state machine flows by utilizing provided state machine helpers to verify screen transitions and state changes. This allows you to validate loading, error, and multi-step navigation logic independently of the UI layer.

Yes, you can reuse existing ScreenModel patterns when building a UI state machine. The implementation integrates directly with your current architecture to drive screen models and the presentation layer without requiring a complete rewrite.

You manage loading and error states for Android and iOS screen flows by configuring a Type 2 state machine. This approach applies predictable state transitions and handles errors uniformly across existing cross-platform navigation patterns.
