## 1. Come creare un Custom Layout in Compose?

**Risposta**

Si usa la funzione Layout { measurables, constraints -> }. Permette di misurare i figli con measurables.forEach { it.measure(constraints) }, poi posizionarli con layout(width, height) { placeables.forEach { it.place(x, y) } }.

## 2. Cos'è SubcomposeLayout?

**Risposta**

SubcomposeLayout permette di comporre i figli dinamicamente in base ai vincoli o alle misurazioni di altri figli. Utile per layout in cui la dimensione di un elemento dipende da un altro (es.: misurare l'header prima di comporre il body).

## 3. Quali sono le 3 fasi del ciclo di vita di Compose?

**Risposta**

Le 3 fasi sono: 1) Composition (creazione dell'albero UI, esecuzione di @Composable), 2) Layout (misurazione e posizionamento degli elementi), 3) Drawing (rendering sullo schermo). Comprendere queste fasi aiuta a ottimizzare le prestazioni.
