Key ideas in Jetpack Compose: Beyond the Basics
- Hoisting state allows a parent to pass in the value and handle the logic
- Stateless components are predictable because they only react to passed parameters
- Stateful composables are harder to test because they own their internal data
- A design system relies on components that don't have side effects or hidden state
- Moving state up makes a component 'stateless' and more reusable
- Statelessness ensures the UI remains a pure reflection of the provided state
- Events bubble up from child to parent via lambda callbacks
- State flows down from parent to child as immutable values
- The UI only updates after the underlying source of truth changes
- remember only persists state during simple recompositions
- rememberSaveable stores data in a Bundle to survive configuration changes
- Process death requires state to be saved in a way the OS can restore
- The architectural benefit of separating state from UI
- The flow of data and events in a Unidirectional Data Flow (UDF) pattern
- The role of stateless composables in a design system
- When to use rememberSaveable versus remember
