Named arguments when calling functions allow explicitly specifying which parameter a value is passed to, improving readability and reducing errors, especially if the function has many parameters or some are optional.
In Flutter (Dart), this is implemented through named parameters in the function definition, which are called by specifying the name:
void greet({String? name, int age = 18}) {
print('Hello, $name! You are $age years old.');
}
// Call with named arguments
greet(name: 'Alexei', age: 25);
greet(age: 30); // name will be null
This approach helps avoid confusion with the order of arguments and allows setting values only for the necessary parameters.
