title: Coc.nvim doesn't seem to be connecting to my lsp
body: <p>My vim setup for flutter development was working fine yesterday, but it seems like coc broke overnight. I'm not getting any linting for errors, and none of my autocomplete/snippets are working. When I try execute <code>coc-codeaction-selected</code>, I get <code>[coc.nvim] No code action available</code>, even though there are definitely actions for the peice of code I'm running it for (i.e. wrap widget).</p>
  <p>Here's my logs from running :CocInfo</p>
  <pre><code>   ## versions

  <p>Any hints as to why this might not be working? I've browsed the github repo's for these plugins and I'm not seeing any issues, so it looks like the problem is on my end. I'm newish to vim, so any help is greatly appreciated!</p>
