Unused function in Vue error compilation

I am facing an issue with the compiler indicating that the function 'show' is defined but never used. The function show is being used in HTML like this:

<b-card>
  <div id="draw-image-test">
    <canvas
      id="canvasId"
      ref="canRef"
      @mousemove="show"
    />
  </div>
</b-card>

This is followed by a <script> tag containing the definition of the 'show' function:

function show(){
  const canvasMouseTrack = document.getElementById('canvasId')
  const rect = canvasMouseTrack.getBoundingClientRect()
  console.log(rect.offsetX)
}

Despite this, I am encountering the following error:

'show' is defined but never used         no-unused-vars

<script>
  export default{

   methods:{
    show:function(){
      const canvasMouseTrack = document.getElementById('canvasId')
      const rect = canvasMouseTrack.getBoundingClientRect()
      console.log(rect.offsetX)
    }
    }
}
