Get started

brightness

namespace

Set app-scoped screen brightness for a reader, scanner or presentation, then restore the system setting when that mode ends.

Temporarily change brightness

tsx
import { Text, brightness } from 'kuito';

brightness.level.value = 1; // a QR code, a boarding pass
<Text>{`${brightness.level.value ?? '…'}`}</Text>;
await brightness.restore();

Behavior and limits

brightness.level is writable and uses the range 0–1. brightness.system reports the system value. Call restore() when the temporary mode ends; use lifecycle cleanup when a screen owns the change. A brightness override is different from keeping the screen awake.

Read Keep awake for the related workflow. The API reference lists every method, option, event and return type.
