如何在React Native中获取base64的图像

我正在使用反应原生图像选择器和图像缩放器来挑选然后调整图像大小.调整大小后,如何获取图像的base64？

ImagePickerManager.showImagePicker(imagepicker_options, (response) => {
  ImageResizer.createResizedImage(response.uri, 550, null, 'JPEG', 100).then((resizedImageUri) => {
    //get base64 of image
  });
});

https://libraries.io/npm/react-native-asset-library-to-base64

ImagePickerManager.showImagePicker(imagepicker_options, (response) => {
  ImageResizer.createResizedImage(response.uri, 550, null, 'JPEG', 100).then((resizedImageUri) => {
      //get base64 of image, uri is link to asset-library://
      ReadImageData.readImage(uri, (imageBase64) => {
    console.log(imageBase64);
    });
  });
});
