Learn how to implement dependency injection into ViewModels using Hilt in Android development. Explore the advantages of constructor injection over field injection and discover how Hilt simplifies ViewModel instantiation in Fragments and Activities. Master the "by viewModels()" method for maintaining ViewModel instances in Fragments and the "by activityViewModels()" method for sharing ViewModels across multiple Fragments with a common host Activity. Follow along with practical examples and gain insights into efficient package structuring, ViewModel building, and dependency injection techniques for Android applications.
