Implement login functionality in the view model using firebase authentication to sign in with email and password, validate fields, manage progress, and fetch user data on success.

Update the login screen user interface to mirror the signup screen, using email and password fields, integrate the nav controller and view model, and enable automatic navigation after login.

Implement a view model logout function that signs out Firebase auth, resets the signed-in flag, clears user data, and preserves profile fields with the Elvis operator while notifying logged out.

Add gender and gender preference to the user data model using an enum, update the view model mappings, and clean Firestore and authentication data before building the profile screen.

Build the Android profile screen with back and save actions, editable name, username, and bio, plus gender options, a profile picture update, and a logout button.

Build and refine a profile screen user interface in Android Jetpack Compose by wiring image URL, text fields for name, username, bio, gender and preference radios, dividers, and logout action.

Update profile data in the backend by calling the view model's update profile data with name, username, bio, gender, and gender preference on save, reflecting changes in Firestore.

Create a circular profile image in Jetpack Compose loaded from a URL. Enable changing the picture and show a loading spinner while loading.

Upload a user profile image to Firebase Storage, update the database with the image URL, and refresh the profile screen after selecting an image via an activity result contract.

Address a profile screen bug by robustly handling null or empty gender values and preferences, defaulting to male and female, to ensure reliable swipe functionality in Android Jetpack Compose.

Update user data type adds swipes left, swipes right, and matches as lists, updates the user map, and guides deleting old data and recreating test users to implement swipe functionality.

Populate cards retrieves potential matches from Firebase according to the user's gender and preferences, excludes self and prior swipes or matches, and updates the UI through a private populateCards function.

Turn the swipe screen into a swipeable card deck using user data and a profile card, controlled by the view model; implement left/right swipes for like or dislike.

Demonstrate like and dislike logic by updating swipes left or right, handling reciprocal matches, creating chat entries, and defining chat data structures in Firebase.

Run the app to test left and right swipes and verify matches in Firebase, as Alex, Jane, and Betty authenticate and interact; prepare for implementing the chat screen next.

Populate the chat list in the viewmodel by querying chats where the current user is in user one or user two, and listen for updates with addSnapshotListener.
