theakhinabraham/doable-todo-list-app ? reverse-engineered prompt

Build me a simple offline todo list app for Android and iPhone with a clean, modern Material style.

I want users to be able to add, edit, and delete tasks, give each task a title and optional note, pick a date and time, and turn on reminder notifications. It should also support repeating tasks like daily, weekly, or monthly, with the option to choose specific weekdays for weekly repeats. The main screen should show the task list clearly, let people mark items complete, swipe to delete completed tasks, and filter tasks by date, time, completion, repeat rules, and reminders.

Please store everything locally so it works without internet, and add a settings screen with an option to clear all data. Keep the app simple and polished, and make sure it feels fast and easy to use. If you need to look up current Flutter or notification docs online, go ahead.
