When you import svg it gets pixelated.

So increase the size in svg file if it's too blurry. height="128" width="128" (add to parent svg tag)

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" fill="currentColor" class="w-6 h-6">
  <path fill-rule="evenodd" ="M2.25 12c0-5.385 4.365-9.75 9.75-9.75s9.75 4.365 9.75 9.75-4.365 9.75-9.75 9.75S2.25 17.385 2.25 12zm13.36-1.814a.75.75 0 10-1.22-.872l-3.236 4.53L9.53 12.22a.75.75 0 00-1.06 1.06l2.25 2.25a.75.75 0 001.14-.094l3.75-5.25z" clip-rule="evenodd" />
