So i had a bit weird warning from eslint
'./types' is a flow type file. I think eslint read checkbox as a lowercase while in reality it is Checkbox (capital C).
I try git mv casesensitive tmp && git mv tmp CaseSensitive
as discussed here: In a Git repository, how to properly rename a directory? but it still doesnt work.
because in the past that folder is lowercase (checkbox) and renamed to Uppercase (Checkbox) but it was work of other developer, i don't know what happen in his machine until this warning come in my machine. Maybe (another assumption) it was happen because of bad config of webpack/babel, im not sure.
