Usage

Linear progress

A horizontal bar that fills to indicate progress. Provide a progress value between 0 and 1 for determinate mode.

LinearExample.tsx

import {
  Host,
  LinearProgressIndicator,
} from '@expo/ui/jetpack-compose';

export default function LinearExample() {
  return (
    <Host matchContents>
      <LinearProgressIndicator progress={0.5} />
    </Host>
  );
}

Circular progress

A spinning circle whose stroke grows to indicate progress.

CircularExample.tsx

import {
  Host,
  CircularProgressIndicator,
} from '@expo/ui/jetpack-compose';

export default function CircularExample() {
  return (
    <Host matchContents>
      <CircularProgressIndicator progress={0.75} />
    </Host>
  );
}

Indeterminate

Omit the progress prop to animate continuously without indicating a specific completion level.

IndeterminateExample.tsx

import {
  CircularProgressIndicator,
  CircularWavyProgressIndicator,
  Column,
  Host,
  LinearProgressIndicator,
  LinearWavyProgressIndicator,
} from '@expo/ui/jetpack-compose';

export default function IndeterminateExample() {
  return (
    <Host matchContents>
      <Column verticalArrangement={{ spacedBy: 16 }}>
        <LinearProgressIndicator />
        <CircularProgressIndicator />
        <CircularWavyProgressIndicator />
        <LinearWavyProgressIndicator />
      </Column>
    </Host>
  );
}

Custom colors

Use color for the indicator and trackColor for the background track.

ColorsExample.tsx

import {
  Host,
  CircularProgressIndicator,
} from '@expo/ui/jetpack-compose';

export default function ColorsExample() {
  return (
    <Host matchContents>
      <CircularProgressIndicator
        progress={0.6}
        color="red"
        trackColor="#cccccc"
      />
    </Host>
  );
}

Wavy variants

LinearWavyProgressIndicator and CircularWavyProgressIndicator add an expressive wave animation from Material 3 Expressive.

WavyExample.tsx

import {
  Host,
  LinearWavyProgressIndicator,
  CircularWavyProgressIndicator,
  Column,
} from '@expo/ui/jetpack-compose';

export default function WavyExample() {
  return (
    <Host matchContents>
      <Column verticalArrangement={{ spacedBy: 16 }}>
        <LinearWavyProgressIndicator progress={0.6} />
        <CircularWavyProgressIndicator progress={0.6} />
      </Column>
    </Host>
  );
}
