fix: Missing space before function parentheses ?

Eslint standard required:

Missing space before function parentheses

beautify result:

    export default {
        data() {
            return {
                input: ''
            }
        }
    }

expected:

    export default {
        data () { // this row
            return {
                input: ''
            }
        }
    }
