Break on all exceptions occurring in my code

[shyndman]

There are lots of cases where exceptions are used as flow control in external libraries, which limits the value of breaking on "All Exceptions" because of all the false positives.

It would be really nice to limit to breaking on all exceptions that occur in code under my control. Feels like it could be a nice complement to the new debug scoping button (the one that reads "Debug my code + packages + SDK").

If I understand correctly, you want to break on "all exceptions in my code" and "unhandled exceptions in other code"?

This is not currently possible from the VMs APIs - and it may be tricky to implement. The VM doesn't have a concept of "my code", it just knows which libraries are debuggable/not (the VS Code extension makes the decision about which libraries to mark as debuggable based on the settings). I think implementing it would require the VM to support setExceptionPauseMode per-library (instead of once globally). Could you open the request at https://github.com/dart-lang/sdk and should it be implemented in the VM, we can update the extension here to use it. Thanks!
