In Dart, arguments of a constant creation must be constant expressions. A constant creation is a type of expression that is used to create a constant value. These expressions are typically used to define constants, such as a number or a string, that will not change during the execution of a program. To ensure that the arguments of a constant creation are constant expressions, you can use the const keyword followed by the expression that you want to create a constant value for. For example: const num = 5;

In this example, the const keyword is used to create a constant variable named num. The expression 5 is used as the constant value for this variable. This means that the value of num will never change during the execution of the program. It's also important to note that when creating a constant value in Dart, you can use the = operator to assign the value of a constant expression to a variable. For example: const num = 5; num = 10;

In this example, the value of num is updated to 10 because the = operator is used to assign the value of 5 to num. I hope this helps! Let me know if you have any other questions.
