    }).bind(this), 1000);

    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
        <Text style={styles.instructions}>

          Press Cmd+R to reload,{'\n'}
          Cmd+Control+Z for dev menu

        <ProgressBar
          fillStyle={{}}
          backgroundStyle={{backgroundColor: '#cccccc', borderRadius: 2}}

          progress={this.state.progress}

    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,

Properties

progress

The progress value for the progress bar. Ranges from 0..1.

easing

The easing function which is applied to the animation. Can be custom or one of the functions on the ProgressBar.easingTypes object.

easingDuration

The time taken to complete the animation.

fillStyle

The style for the progress bar fill.

backgroundStyle

The style for the progress bar's background.

style

The style for the entire component. This doesn't really differ from the backgroundStyle property. You must set width either here or in backgroundStyle in order to make sure the component works properly.

Component methods

update(progress)

The recommended way to update the progress of the progress bar is to use the progress property. If you prefer, you can use this update method to update the progress directly. To access this method, set the ref property on the <ProgressBar> and call this.refs.progressBarName.update(0.3)
