:CocFix doesn't work

[rasuru]

Hello, @iamcco! Thank you for the extension. My issue is I get nothing when I run :CocFix. It seems coc runs quickfix with :CocAction quickfix, and coc-flutter runs :CocAction -quickfix, right? I discovered this by accident, and I could simply remap :CocFix to using :CocAction -quickfix instead, but is this behavior expected?

To Reproduce
Steps to reproduce the behavior:

1. Run :CocFix
2. See Press ? on normal mode to get help..

Expected behavior
Quickfixes, e.g. imports, making a field final, create non-existing variable.

Desktop (please complete the following information):

• OS: Linux
• Vim or Neovim: Neovim
• (Neo)vim version: 0.4.4

[iamcco]

I don't know what CocFix do, seems more relative to coc. Need time to see the code of coc what does it do when run CocFix.

[Kavantix]

This is indeed caused by coc
it only picks quickfix actions that have kind quickfix but the dart server for instance returns quickfix.import

[Kavantix]

This should be fixed now in the master branch of coc.nvim
