Delay when inserting lines in Dart files using flutter-tools.nvim

[ellik159]

Describe the bug
Delay when inserting lines in Dart files using flutter-tools.nvim

To Reproduce

1. Install flutter-tools
2. Open a Dart file in a Flutter project.
3. Try to insert a new line using the 'o' command in normal mode.

Expected behavior
I've been experiencing a specific performance issue with flutter-tools.nvim. While using other languages and plugins, everything works smoothly. However, when I'm working with Dart files in a Flutter context, there's a significant delay when I try to insert new lines.

Update -> Error only in windows.

[siduck]

your loading order of plugins seems to be problematic to me, i'll test it tomorrow

[minocrafft]

The same thing happens to me.

• macbook air - M1 / Ventura 13.4.1
• iterm2
• Neovim 0.9.0

Maybe it's not just about Windows

[siduck]

how do i installed dart lsp? i just installed the dart package from arch repos

[ellik159]

But in linux works fine with the same order of plugins,but i come from lunarvim , and the same config works.

[ellik159]

There is the problem i think , this plugin use its own lsp integration

looks like an issue related to your OS then, not a nvchad issue. open this issue if you're able to make it work with a non nvchad config

this is a minimal nvim config https://github.com/NvChad/basic-config

[ellik159]

The problem is treesitter

@minocrafft
Temp Fix.
Go to override file in custom and disable ident in dart.

 indent = {
    enable = true,
    disable = {
      "dart"
    },
  },
}

:Lazy sync

[siduck]

@ellik159 good catch!

[minocrafft]

I see, there is no delay anymore.

Thanks!
