getCurrentUser

Gets the currently authenticated user, if any.

This is a synchronous operation that returns immediately with the cached authentication state from Firebase. It does not perform any network operations.

Use Cases

• Check if user is signed in before showing authenticated content

• Get user ID for database queries

• Display user profile information

• Initialize app state based on auth status

Example

val currentUser = authDataSource.getCurrentUser()
if (currentUser != null) {
    // User is signed in, show authenticated content
    loadUserData(currentUser.id)
} else {
    // User is signed out, show login screen
    navigateToLogin()
}
