Let’s take an example to understand the if else statement for conditional rendering. We will display the counter on screen and use the edit button to update the counter. Once you click on the edit button then we will change the layout and display the update screen where you can update the counter and save it.

Screen 1:

Display Screen - Clue Mediator
Display Screen – Clue Mediator

The below screen will be displayed when you click on the “Edit” button.

Screen 2:

Edit Screen - Clue Mediator

We will be redirected back to Screen 1 on the click of the “Update” button.
