How do you default a value in Dart?

In Dart, we can assign default parameter values in a function definition , so when we call that function with no argument passed for a parameter then its default value assigned.

Like all functions, a constructor can have default arguments . They are used to initialize member objects. If default values are supplied, the trailing arguments can be omitted in the expression list of the constructor.
