Describe the problem

The example code supplied for demonstrating how to handle errors in asynchronous code is not right. The lead in states:

Run the following example to see how to handle an error from an asynchronous function. What do you think the output will be?

But the sample code is:

void main() {
  for (int i = 0; i < 10; i++) {
    print('hello ${i + 1}');
  }
}

Which has zero errors and zero asynchronous functions.

Expected fix

Sample code that demonstrates the issue being discussed in the code. In fact, this sample seems to be boilerplate as it is repeated multiple times on the page.

Additional context

No response

I would like to fix this problem.

• I will try and fix this problem on dart.dev.

Yeah. The injection script has an issue with sending events at the wrong time. I'm investigating now - dart-lang/dart-pad#2893
