}

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

Note : it's in a .vue file, in the template part

<template slot="top-left" slot-scope="props">
    <div>Hello there</div>
</template>

What did you expect to happen?
No error
Note : it was note raising any error the last time I opened this project about 2 month ago. the slot-scope="props" is necessary for quasar-framework to know where to put the element, but I don't use props myself

What actually happened? Please include the actual, raw output from ESLint.
[eslint-plugin-vue]
[vue/no-unused-vars]
'props' is defined but never used

you can change like this

<template slot="top-left" slot-scope="{}">
    <div>Hello there</div>
</template>

@Eflet. Thank you for suggesting a solution.

If destructuring assignment is not available in your environment, use the ignorePattern option.
