Dart by Example: For

1. main() {

3. for (var i = 0; i < 3; i++) {
4. print(i);
5. }

8. var collection = [3, 4, 5];
9. for (var x in collection) {
10. print(x);
11. }

13. // Closures will capture the value of the index (Dart is lexically scoped)
14. var callbacks = [];
15. for (var i = 6; i < 8; i++) {
16. callbacks.add(() => print(i));
17. }
18. callbacks.forEach((c) => c()); // invoke each callback
