To-do list mobile app

You will create a to-do list application by using your preferred mobile application development framework. People are finding it harder and harder to remember and manage daily tasks in this fast-paced world. By creating a to-do list app, users can create and manage their daily tasks more easily.

• The application should open with a splash screen
• There should be three categories at the top of the screen:
  • Pending
  • Completed
  • Overdue
• If the to-do list is empty, show an empty state message: “No items to display. Please press “Add” to add new items.”
• Show a fixed navigation bar at the bottom of the screen with an “Add” button, which allows the user to create a new task
• Clicking the “Add” button will show a screen with the following elements:
  • Title (text input field)
  • Description (text input field)
  • Deadline (iOS or Android default date and time selector)
  • Confirm button
  • Cancel button
• Each new task should have a deadline later than the current time. Adding a task will save it to the file storage in the text file.
• Users can perform different actions by selecting single or multiple items:
  • “Pending” category
    • One item selected: the user can press “Delete,” “Edit,” or “Complete”
    • Multiple items selected: the user can press “Delete” or “Complete”
  • “Overdue” category
    • One item selected: the user can press “Delete,” “Edit” or “Complete”
    • Multiple items selected: the user can press “Delete” or “Complete”
  • “Completed” category
    • One item selected: the user can press “Delete” or “Edit”
    • Multiple items selected: the user can press “Delete” or “Edit”
• When the user presses on the “Edit” button, a screen should pop up with:
  • Title (text input field with pre-filled data)
  • Description (text input field with pre-filled data)
  • Deadline (iOS or Android default date and time selector with pre-filled data)
  • Confirm button
  • Cancel button
  • Complete button
• 10 minutes before the deadline of a task, users will receive a push notification to remind them of the task

• For iOS development, implement the app using Swift
• For Android development, implement the app using Java and the Android SDK
• To learn how to build multi-platform apps, use React Native

Before you begin the development of the application, make sure you understand the basic requirements of the application. It's always a good practice to create a sketch of the screens. Also, do check out existing to-do list applications on the Google Play Store and the App Store to gain an idea of the look and feel of similar applications.
