Lazy composables in Jetpack Compose enable efficient rendering and scrolling of large lists or grids. Navigation in Jetpack Compose provides a powerful way to navigate between different screens or destinations within an app. Together, lazy composables and navigation enhance the user experience by enabling seamless scrolling and smooth transitions between screens in Jetpack Compose apps. In this course, you will learn how to efficiently display large lists of items using the lazy column and preserve their state across screen rotations or app restarts. Next, you will explore the lazy grid, and with the help of the coil library, you will asynchronously load images in your Compose app. Then you will set up the NavController and NavHost and define the structure and connections between different screens. You will also examine advanced techniques for passing data between composables and querying data from the data layer. Finally, you will test your app on a real Android device and implement navigation using the bottom navigation bar. When you are finished with this course you will have the skills and ability to develop multiscreen applications using Jetpack Compose.
