The problem you want to solve.

I have noticed some of the rules do not work properly when using vue-property-decorator, for example:

'vue/require-default-prop': 'warn' does not detect properties decorated in the form

@Prop({type: String}) readonly propA: string;

does not raise any error even though the prop has no default value.

Additionally,

'vue/prop-name-casing': 'warn'

does not detect properties such as

@Prop({required: true}) readonly file_filter!: FileID;

Your take on the correct solution to problem.

These rules should properly analyze properties declared using @Prop.
