The variable has been declared but goes unused (no-unused-vars)

Apologies for my English not being perfect :) I have used the event Emit and on methods to transfer variable details from one module to another. The issue I am facing is mentioned above. Here is my code:

In the App.vue file

<v-btn class="ma-2" @click="closeModal()" tile large color="teal" icon>
              <v-icon>mdi-menu</v-icon>
            </v-btn>

methods: {
    closeModal() {
      this.mini = !this.mini;
      Event.$emit("i-got-clicked", this.mini);
    }
  }

In the left navigation file

<v-content :v-show="mini">

mounted() {
    Event.$on("i-got-clicked", mini => {
    //Although 'mini' appears to be defined, it is never actually used
      this.mini = !this.mini;
    });
  }

I would greatly appreciate any answers. Thank you in advance!

Answer №1

The issue lies in the initial line of code:

Event.$on("i-got-clicked", mini => {

In this snippet, a variable named mini is declared but never utilized in the subsequent code. It's important to note that mini is distinct from this.mini.

If you determine that mini is unnecessary, you can revise the code as follows:

Event.$on("i-got-clicked", () => {

Alternatively, consider adjusting the following line of code instead:

Event.$on("i-got-clicked", mini => {
  this.mini = mini;

Answer №2

:v-show is the same as using v-bind:v-show, but this may not be what you intended. It would actually bind a variable named v-show to that specific element. To avoid confusion, it's best to just use v-show without the unnecessary colon in front of it. Otherwise, Vue won't recognize it correctly.

To learn more about the shorthand notation for v-bind, check out the documentation here.
