Current Behavior

Neovim LSP autocompletes everything twice only when working with Flutter(dart). I am not facing this problem while working with other programming languages. I have uninstalled Dartls lsp server and using Flutter-tool.nvim. Still facing the same problem.

Steps To Reproduce

LSPInfo output:

1 client(s) attached to this buffer:
