Hello! I noticed that the lychee link checker was failing on the Dart track due to a broken Gitter link and several redirects in the documentation.
I have already opened a PR to fix these here: (fix: update broken community links by Aadarsh7776 · Pull Request #644 · exercism/dart · GitHub)].
The changes include:
Updating the Gitter link to the Dart Discord.
Removing www. from dart.dev links to prevent redirects.
Could a maintainer please review and reopen the PR?
