'v-slot' directive doesn't support any modifier

I don't see any v-slot in the code you provided so I can show you only my usecase.

With Eslint error:

<template v-slot:item.actions="{ item }">

Without error:

<template v-slot:[`item.actions`]="{ item }">

In eslint-plugin-vue@^7.1.0, you can use allowModifiers option in vue/valid-v-slot rule.

// .eslintrc.js'vue/valid-v-slot': ['error', {  allowModifiers: true,}],

vue/valid-v-slot #options

EDIT: As notified by the comments and Hexodus' (correct) answer, you can work around the linting warning by using dynamic slot names that return a string(template). 'Not enabling' is no longer recommended, as this is now a standard rule. Thus, I recommend using Hexodus' method over disabling the valid v-slot rule altogether.

Original Post:

You can't really fix this linting warning.

• Vue syntax for modifiers use the dot to alter the way adirective functions (e.g. v-model.number)
• The way Vuetify dynamically names their slots uses a dot in order toselect a specific part of the component (#header.data-table-select).

ESLint can't distinguish whether you're trying to set a modifier on a slot (which is impossible), or if you have a slot name that contains a dot.

The easiest thing you can do is disable the rule. Since the 'valid-v-slot' rule isn't enabled by default by any of the base configurations of eslint-plugin-vue, you should be able to find it under "rules" in your eslint config.
