how to save image?

how to save img in flet app?

def save(e):
    p =  e.control.page
    p.launch_url( e.control.content.src )

img = Image( src='aa.png')
c = Container( content=img, on_click=save )

You are working in Python, just download the image using any Python HTTP library and save it to a file.

I would like to bump this request. Perhaps adding a serve_content.go to the server package. Not sure if I am phrasing that correctly. I have no experience with Go, but think it should be possible?
Flet is awesome, but many apps perform some sort of file manipulation. It would be nice if web users could download the results. Seems redundant to use flask or fastapi as a backend to the backend, just to serve files.

It's already possible. I'm not sure I understand the issue. You can put files that must be downloadable to assets directory and then present user a link or perform redirect to that file to cause download. Could you please elaborate what are you trying to achieve?

apologies for the late reply.
if this seems like a noob question... it is. imma a total noob when it comes to web dev.
i tried a redirect like you suggest, but get varied results, with different file types.
i made a short example here--> https://github.com/aedhcarrick/test-dl
seems the browser tries to open the file when the link is opened. in the case of zip files, it downloads, cause it doesn't know what else to do, but chrome at least, doesn't give the option of where to save. also, I haven't tested yet, but i can foresee problems occurring with large (>7.5GB) downloads or even multiple concurrent ones. I was thinking of an approach like the one mentioned in the answer to this question on stack overflow.--> https://stackoverflow.com/a/24116517
Would be nice to modify header content and stream the response body (in case of large files).
apologies again, if i am just further confusing the issue.

if i understand correctly, marking the file as an attachment (in the header), would trigger the browser's native file dialog.
