In Dart, you can use the conditional operator ? : : to assign values based on a condition. This is often referred to as the ternary operator.
The syntax for the ternary operator is:
condition ? expression1 : expression2;
If condition is true, expression1 is executed and assigned to the variable. If condition is false, expression2 is executed and assigned to the variable.
Here's an example:
bool isTrue = true;
String value = isTrue ? 'This' : 'That';
print(value); // output: This
In this example, the isTrue variable is set to true. When we use the ternary operator to assign a value to the value variable, it checks if isTrue is true. Since it is, it assigns the string 'This' to the value variable.
Let's take a look at another example:
bool isTrue = false;
String value = isTrue ? 'This' : 'That';
print(value); // output: That
In this example, isTrue is set to false. When we use the ternary operator to assign a value to the value variable, it checks if isTrue is true. Since it is not, it assigns the string 'That' to the value variable.
I hope this helps you understand how to use the ternary operator to assign values in Dart!
