You can create your own component, let's say something like a ProgressBar component and then feed it a width or complete % with a state param...

<IndicatorViewPager onPageSelected={this.yourOnPageSelected} ...>

...

yourOnPageSelected = (params) => {
  this.setState({
    progress: ((params.position + 1) / numOfSteps),
  });
}
