For example, one should be able to call
print(repeatString("*", 10));
and get
// Adding this line so we can perform the variable assignment: num eachElement = 0; | |
// ignore_for_file: unused_local_variable | |

This class is a little bit different than the [ValueNotifier] class: | |
- Setting the value ALWAYS notifies listeners, even if the value is the same. | |
- It uses streams over [ValueListenableBuilder]'s setState approach to make it | |
easier to use with other async code. |
