Component methods

| Method | Description | |---|---| | 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) |
