Getting Bool State from Firestore in Dart

[Alvaro-99]

I am trying to get a bool value from Firestore when the app is being initialized: it returns True if it is "like" and False if it is not "like". Every time a user likes/unlikes a post, a database (called userFavorites) is being created or update on Firestore. So when initializing the app, I'm trying to get access to this True/False for each of the posts that are being displayed on the UI (if the user has never liked or unliked the post, the value for this bool will automatically be False). I have been researching and working on it for a while (also used the debugger and breakpoints every time), and the problem that I am having is that I am not able to get and display the T/F bool value from the Firestore database into the UI each time a post is initialized (or seen on the screen). What code could I use to do that? I would really appreciate your help here. Thanks!
