How to use Firebase Storage url as react-native Image's source

Im trying to view an image that was stored in Firebase storage, but when I use the download url in <Image />'s source prop, I get a warning:

Warning: Failed prop type: Invalid prop source supplied to Image.

upload function:

const Blob = RNFetchBlob.polyfill.Blob;
const fs = RNFetchBlob.fs;
window.XMLHttpRequest = RNFetchBlob.polyfill.XMLHttpRequest;
window.Blob = Blob;

 uploadImage = async (uri, mime = "application/octet-stream") => {
    if (this.state.uploadable == "") {
      alert("No image selected");
    } else {
      const uploadUri =
        Platform.OS === "ios" ? uri.replace("file://", "") : uri;
      const sessionId = new Date().getTime();
      let uploadBlob = null;

      const imageRef = firebase
        .storage()
        .ref("userSpecificFolder")
        .child("profileImage");

      fs.readFile(uploadUri, "base64")
        .then(data => {
          return Blob.build(data, { type: `${mime};BASE64` });
        })
        .then(blob => {
          uploadBlob = blob;
          return imageRef.put(blob, { contentType: mime });
        })
        .then(() => {
          uploadBlob.close();
          return imageRef.getDownloadURL();
        })
        .then(url => {
          this.setState({ storedImg: url });
          resolve(url);
        })
        .catch(err => {
          reject(err);
        });
    }
  };

download function: 

downloadImg = () => {
    firebase
      .storage()
      .ref("userSpecificFolder/profileImage")
      .getDownloadURL()
      .then(url => {

        this.setState({ storedImg: url });
      });
  };

Implementation: 

<View> 
  <Image source={this.state.storedImg}/>
</View>

If this isn't the way to view an image from Firebase storage what steps are missing?

ps, ive tried the answer posted here with the same outcome mentioned above.

The issue was with the implementation. For some reason the url needs to be the value of the uri property in an object. <Image source={{uri: *url* }} /> and the image displays.
