How will i get url of image from gallery ? I am following this but the url is hardcoded. what i wanted to do is to to get url of any image i upload and convert it to tensor and also everytime i upload an image it's url is definitely going to be changed? since i am new, i am not able to figure this out that how to get that url although it is maintaining uri in the state.

  const image = require('path/to/img.jpg');
  const imageAssetPath = Image.resolveAssetSource(image);
  const response = await fetch(imageAssetPath.uri, {}, { isBinary: true });
  const rawImageData = await response.arrayBuffer();
  const imageTensor = decodeJpeg(rawImageData);
