Dart 语法高亮在 vs 代码中不起作用

Question

i have been using vs code for flutter for 3 months and now i got into this issue syntax prediction works and flutter run is also working but syntax color is gone

Also i have uninstalled every extensions and reinstalled vs code here is the console screenshot

Answer 1

It appears that one of the files in the Dart extension may be corrupt on your disk (syntaxs/dart.json). I would try to uninstall the extension and re-install it.

If that does not help, please check the contents of the.vscode-extensions folder in your home directory in the Dart-Code folder syntaxes/dart.json and see why it is not valid json.

I've seen this once before ( https://github.com/microsoft/vscode/issues/73134 ) though it's not clear why it happened.
