Storage file download with Flutter on web

Hey, I'm developping a Flutter web app and I used the Storage service to upload files (pdf, jpg, png). I am having troubles to download these files because the documentation example is probably designed for mobile Flutter apps. After a bit of research I am implementing the file download with a method executing this code : (with 'dart:html' as html)

html.window.open('http://localhost/v1/storage/buckets/$BUCKET_ID/files/$FILE_ID/download?project=$APPWRITE_PROJECT_CUSTOM_ID&mode=admin', "Download");

I have the feeling that it is not the recommended and safest way of doing it, but I could not find any other one. Could you please tell me how I could properly implement it?
Thanks in advance,

Btw, you shouldn't use mode=admin in your app.

It seems flutter web is hacky in general. You can do it the way you've done or you can call the download method using the SDK and then do something like this: https://stackoverflow.com/questions/65431345/flutter-web-download-file-from-url-instead-of-opening-it
