“Flutter Code extension not installed” but it's been installed for months

Question

Have been using Flutter with VSCode on Mac for months without issues, but suddenly flutter doctor produces this:

[✓] Flutter (Channel beta, v0.5.1, on Mac OS X          


        

Answer 1

Install the Flutter extension within VS Code.

Answer 2

There was a change in VSCode that broke extensions detection. It's safe to ignore this warning.

See the full comment of Danny Tuppeny, about this issue here.

For the stacktrace there are two things:

• The asset "ios/Flutter/flutter_assets/fonts/MyFlutterApp.ttf"was not found
• The issue with obsvervatory

Did you check the asset still exists? The project does not compile without it, and the observatory issue may be related to this.
