Pass data between destinations; Create a deep link for a destination; Animate transitions between destinations; Update UI components with NavigationUI; Kotlin DSL; Type safe navigation with Compose; Interact programmatically; Navigate with feature modules; Best practices for multi-module projects; Test navigation; Add new destination types The flow to send a String data from one Fragment to another is shown below. To pass data between fragments we need to create our own interfaces. Similarly, we can share other data types as well. Note that select Java as the programming language.. Since fragment is a small portion of the bigger user interface, it can only be initialized inside an activity or another fragment. Below is the code for the activity_main.xml file.
