Chapter 6: Control Flow

Examples

If Else

Dart has If Else:

if (year >= 2001) {
print('21st century');
} else if (year >= 1901) {
print('20th century');
} else {
print('We Must Go Back!');
}

Dart also has a ternary if operator:

var foo = true;
print(foo ? 'Foo' : 'Bar'); // Displays "Foo".

While Loop

While loops and do while loops are allowed in Dart:

while(peopleAreClapping()) {
playSongs();
}

and:

do {
processRequest();
} while(stillRunning());

Loops can be terminated using a break:

while (true) {
if (shutDownRequested()) break;
processIncomingRequests();
}

You can skip iterations in a loop using continue:

for (var i = 0; i < bigNumber; i++) {
if (i.isEven){
continue;
}
doSomething();
