Describe the bug

When I edit this particular file on emacs, the LSP Dart Server dies, repeatedly.

The changes I was making are included below.

The server logged this to stderr:

To Reproduce

Here's the changes I was making to the file:

Expected behavior

LSP Dart continues helping me a lot.

Version

I've just upgraded to latest, tried again, same result.
