How can I change the tab size for all Dart files?

I know the "standard" is 2 spaces, but I hate that look and I've always used 4 spaces for everything. I've tried editing the languages.toml file, but that hasn't seemed to work.

Any help appreciated!

You'll want to create a custom languages.toml that overrides the indentation settings for dart:

# ~/.config/helix/languages.toml
[[language]]
name = "dart"
indent = { tab-width = 4, unit = "    " }

It sounds like they already tried this, so maybe they're running into the automatic indentation detection.

Ah that seems to work! I edited the languages.toml in the root directory, and creating this file seems to have worked!
Thank you!
