How to use the reactfire.useStorage function in reactfire

const ImageUploadButton = props => {
  const [uploadTask, setUploadTask] = useState(null);
  const [ref, setRef] = useState(null);
  const storage = useStorage();
  const onChange = event => {
    const fileList = event.target.files;
    const fileToUpload = fileList[0];
    const fileName = fileToUpload.name;
    const newRef = storage()
      .ref('images')
      .child(fileName);
    setRef(newRef);

    const uploadTask = newRef.put(fileToUpload);

    uploadTask.then(() => {
      console.log('upload complete');
      setUploadTask(null);
    });
    setUploadTask(uploadTask);
