Ternary Conditional operator in Flutter(Dart)

One of the best features of the Flutter framework is its support for the ternary conditional operator. This operator allows you to concisely express if-else logic in your Flutter code. In this article, we'll take a look at how to use the ternary conditional operator in Flutter.

The ternary conditional operator is a shorthand way of expressing if-else logic. It is often used in situations where a simple if-else statement would suffice, but where using the ternary operator can make the code more concise and easier to read.

String message = isLoggedIn ? 'Hello again' : 'Please sign up';

The basic syntax for using the ternary conditional operator is as follows:

condition ? expr1 : expr2

If the condition is true, then expr1 is evaluated and the value is returned. If the condition is false, then expr2 is evaluated and the value is returned.
