Build me an Instagram style app in Flutter with Firebase for the backend, and make it feel like a real social app people can actually use.

I want users to sign up and log in, edit their profile, follow and unfollow people, post photos and videos, create stories, like and comment on posts and comments, reply to comments, search for users by name, and see feeds based on who they follow. It should also have a separate videos area, activity and notifications, and let people share posts into chat.

Please include one to one chat and group chat with text, images, voice, and video calls using Agora. I also want Arabic and English support, plus dark and light theme switching.

Keep it polished and close to an Instagram feel on mobile and web if possible. Use clean code and make the app structure easy to maintain. If you need to look up current docs online, go ahead.
