I'm currently going through a Dart course, and the instructor's code shows blue squiggly lines under the 'Hello World' example, but mine aren't appearing. This seems crucial, and I don't want to continue without fixing this issue. I've copied the code exactly as shown, but I can't find any blue squiggles. I looked into settings based on other people's suggestions but couldn't find anything that relates to them or what they might be called now.

It sounds like you might be missing some essential tools. Have you installed the Flutter SDK along with the necessary VS Code extensions for both Dart and Flutter?
The blue squiggles usually come from either spell check or linting. Make sure you've enabled these settings in your VS Code. Double-check your settings and if you're looking for syntax error highlights, they might be labeled differently than just 'blue squiggles.'
I did ask about spell check in the VS forum, and while the instructor said there's more to it than that, I'm still left confused! I really want to see the same highlights as him.
