How to get image paths of a list of uploaded images?

I have the following situation.

I am allowing users to upload multiple files. The array of uploaded images is stored inside a page variable called : uploadedImages List <Uploaded File (Bytes)>

Just to let you know, I am only storing these images as "Local Upload <widget state>" and have not uploaded them yet to Firebase.

Now, I want to store this data to Firebase, but it seems that the only options I have to store the file data is via image URL (which I assume needs to be extracted from the page variable.

I have created a Firebase collection field called "images" of type "Image Path" (List).

Now when I try to save the uploadedImages variable, to the Image Path list, I am unable to do it.
I assume that is because database expects Image Path and I am not sure I to generate a list of image paths from my uploaded file list.

Can someone let me know whats the best way to do this?

Thanks
