Usage

This component only exposes an api to update device volume and listens for VolumeChanged events via hardware buttons. There is no UI component included.

// Other imports
...

import ControlVolume, {
  ControlVolumeEvents
} from "react-native-control-volume";
import Slider from '@react-native-community/slider';

class App extends React.Component {
  state = {
    volume: 0
  }

  async componentDidMount() {
    this.setState({
      volume: await ControlVolume.getVolume()
    });

    // Add and store event listener
    this.volEvent = ControlVolumeEvents.addListener(
      "VolumeChanged",
      this.volumeEvent
    );
  }

  // Updates Slider UI when hardware buttons change volume
  volumeEvent = event => {
    this.setState({ volume: event.volume });
  };

  // Updates device volume
  sliderChange(value) {
    ControlVolume.change(value);
  }

  componentWillUnmount() {
    // remove event listener
    this.volEvent.remove();
  }

  render() {
    return (
      <Slider
        value={this.state.volume}
        onValueChange={this.sliderChange}
        // Other props
      />
    )
  }
}
