    [frdp][connection] Exception checks in _getDartVm (#22386) · 1c2f478e
    Andrew Davies authored
    Through some integration testing checks, it looks like it's possible
    that connecting to a new instance of the Dart VM may fail even after the
    Dart VM instance has been discovered.
    
    This means that _getDartVm should be checked in more than just one
    place.  This changes the function to return a null value in the event of
    a 'well-known' exception (`HttpException` or `TimeoutException`
    specifically).
    
    As a result, code now calling _getDartVm checks for null and handles it
    as appropriate, and the DartVm RPC calls are all updated with
    consistent timeout params.
