[Vue warn] with Alert component

[TatChu]

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "show" found in
My code above:

• template:
  <alert :show.sync="alert.show" placement="top-right" :duration="3000" :type="alert.type" width="100%" dismissable> <span class="icon-ok-circled alert-icon-float-left"></span> <p>{{alert.message}}</p> </alert>
