Errors in console when running anything in Flutter Web (Vs Code)

Question

Edit: These messages only pop up in Visual Studio Code's Debug Console. The issue does not occur when running from the terminal. There might be some issue with the Flutter extension.

I'm getting error messages in my console whenever I run anything in Flutter Web and they appear again after every Hot Reload/Hot Restart, even with a freshly created project. Here they are:

Error handling 'checkPlatformOverride' custom request: _flutter.listViews: (-32601) Unknown method "_flutter.listViews".
Error handling 'checkBrightnessOverride' custom request: _flutter.listViews: (-32601) Unknown method "_flutter.listViews".
Error handling 'checkIsWidgetCreationTracked' custom request: _flutter.listViews: (-32601) Unknown method "_flutter.listViews".
Error handling 'serviceExtension' custom request: _flutter.listViews: (-32601) Unknown method "_flutter.listViews".

Any ideas what's causing this? The apps work fine but it takes up a lot of space in the console after a while.

Here is my flutter doctor -v output, for reference (switched to master a few minutes ago to see if that'd fix the issue):
