Building UIs with basic layouts and components

Combine fundamental layouts like Column, Row, and Box to build complex UIs, and create reusable custom components by simply defining new functions.

How Compose works with lifecycle, phases, and state

The UI updates through a lifecycle of composition and recomposition, driven by changes to State objects across three phases: composition, layout, and drawing.

Implementing animations for a more dynamic UI

Easily add basic animations like fades with AnimatedVisibility or animate any property, such as rotation or color, by using state animation functions.
