[Bug] Schedule Screen Checklist not Reflecting Homescreen Updates

[nealetham]

The Checklist within the Schedule screen does not update in real-time. Addition, checking, or deletion of tasks in the Home screen page is not reflected within the FlatList in the Schedule screen.

The checklist is only updated after reloading the expo application.

Possible Solution:

There are two ways to retrieve data stored in Cloud Firestore. Either of these methods can be used with documents, collections of documents, or the results of queries:
Call a method to get the data.
Set a listener to receive data-change events.
When you set a listener, Cloud Firestore sends your listener an initial snapshot of the data, and then another snapshot each time the document changes.

Use the onSnapshot method from Firebase API, instead of getDoc.
