Скачать или смотреть 25. Fixing Cart Count Badge & Navigation to CartFragment

In this video, we’ll fix two key features in our shopping app:
1️⃣ Cart Count Badge – Show the total number of items in the cart directly on the main screen.
2️⃣ Navigation Fix – Ensure tapping the cart icon smoothly navigates the user to the CartFragment.

You’ll learn:
✅ How to share a CartViewModel between fragments using requireActivity()
✅ How to observe LiveData to update the cart badge dynamically
✅ Making the cart experience user-friendly and consistent

This is part of our full Android app development series using Kotlin, MVVM architecture, Room Database, and Single-Activity structure.

💡 By the end of this video, you’ll have a working cart badge and navigation flow integrated into your app!
