Vscode debug run fluent message: there is no extension for debugging yaml. Should we find yaml extensions in the market?

This is a low-level problem , This is the pubspec.yaml When the file is opened and in the focus position, debug the compilation error , Sketch Map ：

You should switch to the project file or switch to main.dart File and in the focus position before debugging and compiling , There will be no error at this time , Do not close pubspec.yaml File and then debug and compile .

open pubspec.yaml Save the file after modification ,vscode Will be executed by default flutter pub get command , Then automatically download dependent files , The premise is that YAML plug-in unit . because pubspec.yaml The file contains special commands , Don't open it when debugging and compiling .
