Flutter, confusion with Network assets

Question

Suppose, I have a product page or a carousel and that fetches network data,

let us discuss the simplest example with the carousel image data retrieved from Image.network.

My question is if I provide the image URLS from a [List], and publish the app. then if I had any need in future to change the Images as well as the Img URLs in that [List] then for that simple task should I have to edit the code recompile and reupload the app?

This doesn't seem Right there must be a better way like a CSV or Sheet file.

If anyone aware of this please help me with a comprehensive guide.
