Flutter Image Picker to Image URL - flutter

Question

i have the following code below. ive used image_picker package to upload pictures to be used as profile pictures. ive commented my previous code that uses an image url instead. my question is if there's a way to convert the images uploaded to images url, that way, i can display the profile picture when i get into the home screen.
