NPE in CacheListCommand #2247

Closed isoos closed 1 year ago

isoos commented 5 years ago

This is probably not new, I've just ignored it for a while. When pana runs pub cache list with package:syntax 0.2.0 it gets this exception:

  Exception: Problem running proc: exit code - 1<***><***>The getter 'name' was called on null.

This can no longer happen as we are null-safe.

I cannot reproduce because package:syntax has been removed.

Please reopen if you can still reproduce a related problem.
