GET for an image is a simple request, it doesn't need CORS.

J

j.purohit198•3/14/24, 11:27 AM

yes. as env variables.

Y

yousefOP•3/14/24, 11:27 AM

flutter run --dart-define=AWS_ACCESS_KEY_ID=... --dart-define=AWS_SECRET_ACCESS_KEY=...

Y

yousefOP•3/14/24, 11:28 AM

run this in your terminal

Y
