In this article, you’ll learn what and how to use Livedata & Kotlin flow. The key differences between them and a real-time example demonstrating the appropriate usage.
Introduction
LiveData is the means to transfer data, which is a common task in mobile development. Kotlin flow also has the ability to transfer data in a unique way and also perform async operations. Both have there limitations and advantages. They are designed to use in specific use-cases to overcome traditional problems.
