00:02At this point, you should feel pretty good idea about working with functions. So naturally, I have a challenge with you. In this episode, you’re going to get three challenges. So let’s get started.

String youAreWonderful

String youAreWonderful(String name) {

}

return 'You are wonderful, $name';

print(youAreWonderful('Douglas'));

String youAreWonderful(String name, int numberOfPeople) {

return 'You are wonderful, $name. $numberOfPeople people think so.';

print(youAreWonderful('Douglas', 10));

String youAreWonderful({ String name, int numberOfPeople } ) 

String youAreWonderful({ required String name, int numberOfPeople } ) 

String youAreWonderful({ required String name, int numberOfPeople = 30} ) 

print(youAreWonderful(name: 'Douglas', numberOfPeople: 10));

print(youAreWonderful(name: 'Jeremy'));
