Commands that have --offline as an option should recommend it when unable to connect. #15717
Description
flutter create and flutter packages get (and others?) have an --offline flag that allows them to work offline if the pub cache is sufficiently full. We should have those commands recommend using --offline if they fail to connect to the server.
Alternatively, we could just go ahead and try to run offline automatically (with a great big warning that we've done so) if we can't connect.

Or have those commands ask if the user wants to run
--offline.gspencergoog commentedon Mar 19, 2018
Well, but asking for user input in a command-line process is not ideal: if it runs inside of a script, then it waits forever, and you end up needing a
--yesoption or something. I'd rather it either do it automatically (and you can turn it off with--no-offline) or not doing it automatically and suggest using--offline.abmoudz commentedon Mar 20, 2018

cc @jcollins-g is this something you can help with?

@mit-mit This looks a little in-depth for me to jump in and fix quickly, currently focused on dartdoc issues. If you need it urgently though assign to me and I'll try and make the time.

I believe @filiph mentioned this is required for I/O?
jcollins-g commentedon Apr 16, 2018
It's too late to get this change in for I/O, way too risky. However I'll take a look at this interleaved with other work.
filiph commentedon Apr 16, 2018
That was my mistake. I though each
flutter runrequires an internet connection, but it turns out only the first one does. We're good for I/O.For reference, this is about #9393 (comment), resolved offline.

Now that we have Dart FFI, perhaps we could wrap some OS APIs for getting the network state?
