Allow seeing the "Return value" of an operation in the debug panel about dart-code HOT 3 OPEN

@bkonyi is there an existing way to get at the return value for a function through the VM Service?

In JS, when you step over a return, there's an extra stop location at the return which includes the return value in the variables list:

In Dart, it seems we have a similar extra stop location (it jumps to before the return keyword):

However, I can't see anything in the VM traffic that indicates the return value so I'm not sure if the reason for this extra stop point was for this reason, or something else.

I'm not aware of any way to do that, otherwise it would have already been available alongside the list of other local variables.

We probably have a step location there since we're about to perform the return after evaluating a + b. If we didn't have that location, we'd simply skip past return in a function that returns void.

This does seem like nice behavior, but we'd need to make service changes. It's probably worth filing an issue for this in the SDK, but I don't think it'll be high priority.

@bkonyi thanks, I've opened dart-lang/sdk#55704
