This will make the outer call to runZoned() return null, correct? Should we wrap that null in a non-zero synthetic exit code?

I don't think so: _handleToolError invoked from this onError handler will terminate the flutter with exit code derived from what kind error the error is(ToolExit, ProcessExit, something unexpected).
If we end up in onError, then runZoned() returned a future that never completes because of unhandled exception.

It'll call exit(), but that can be overridden for tests. I'm just curious what the return value of run() will be in that case.

we only end up in onError through async callback/flow, and that flow won't affect runZoned return-value. We might have used Completer or something similar to communicate between this callback and method that runZoned is executing, but that seems unnecessary - we can simply exit the tool.

We should replicate the case this is guarding against in a test.

One example of unreported errors is #33938 where adb is invoked when broadcast stream is created in a _start callback
