AlharithBajaher/DawaTime_app — reverse-engineered prompt

Build me a simple Flutter app called DawaTime from this starter project. The current README looks like the default Flutter one, so please make reasonable choices and turn it into a clean, usable first version.

I want it to feel like a small personal time reminder app. Users should be able to open the app, see a friendly home screen, add a reminder with a name, time, and short note, then view upcoming reminders in a clear list. Since Firebase files are already in the project, use Firebase for saving the user’s data if it’s already configured, and keep things ready for Android, iOS, and web.

Please make the UI polished but simple, with a calm color theme, empty states, basic validation, loading states, and error messages that normal people can understand. If something is missing, add sensible placeholders and keep the code organized so I can extend it later. Look up current Flutter or Firebase docs online if you need to.
