3 Property cupertino_icons is not allowed.yaml-schema: pubspec.yaml

4 Property flutter_test is not allowed.yaml-schema: pubspec.yaml

5 ect........

using flutter version is 2.8.1

"YAML"(extension) version v1.5.0

Solution 1

Please update VSCode's YAML extension to at least 1.5.1 to resolve the error. Flutter will work as it is with the errors too.

Solution 2

I'm having the same issue with VSCode since this afternoon, everything worked well before. I've tried forcing the schema via # yaml-language-server: $schema=<urlToTheSchema> and yaml.schemas setting, but no luck.

Edit: could be related to upgrading to yaml extension v1.5.0 (cf: https://github.com/redhat-developer/vscode-yaml/issues/708) Temporarily downgrading back to 1.4.0 no longer throws errors.

Solution 3

The YAML extension is using an incorrect schema to validate your YAML file. Ensure that:

• your file does contain a correct # yaml-language-server: $schema=<urlToTheSchema> comment or at least does not contain a wrong one.
• your yaml.schemas setting does not associate your file via glob pattern with an incorrect schema.

The correct schema would be https://json.schemastore.org/pubspec.json. See also Associating Schemas.

Solution 4

I reload the YAML extension and the error gone
