Following is error message when working with dart-mode.

 \")\207" [#<buffer my_transactions_page.dart> (#0) eglot--managed-mode remove-hook post-command-hook nil buffer-live-p apply eglot--connect eglot--guess-contact] 4]): (file-missing "Searching for program" "No such file or directory" "dart_language_server")

From the dart-lang official document, dart start to support Dart analysis server from version 2.2.0 , now it use form like this:

dart language-server --client-id my-editor.my-plugin --client-version 1.2

I don't know when to use --client-id my-editor.my-plugin or --client-version 1.2, but it seem like just work after setting like this:

(setq eglot-server-programs
      `((dart-mode . ("dart" "language-server"))))
