Feat: Implementation of local notifications in the application

[jaivsh]

Describe the feature

I'd implement the local notifications, which would display the local push notifications to the user in case of approaching of important test/event added by the user. I'd use the following plugins for this purpose:

• flutter_local_notifications
• shared_preferences

The notifications would be periodic based on the time difference between the event's time and the current time. Also, there would be different templates of notifications based on weather they are added to favourites or not.
