Is your feature request related to a problem? Please describe.
Currently, users have to open the app to check their tasks, which can be inconvenient and time-consuming. By adding widgets to the device’s home screen, users can quickly view their upcoming tasks and manage their to-do list without opening the app, improving accessibility and usability.

Describe the solution you'd like
Integrate home screen widgets that allow users to view and interact with their tasks directly from their device’s home screen.
Task List Widget: Display a list of upcoming tasks, including task titles and due dates.
Interactive Widgets: Allow users to mark tasks as completed or delete tasks directly from the widget.
