Nit, but please make this a full sentence:

'Unexpected on-zero exit code from $compilerPath.'

Done.

After talking to sgjesse about this, I restored the use of onError. This detects
errors like the executable not being found.

-    print('Failed to compile $dartPath with $compilerPath. Error:');
-    print(error);
-  };
