Support for plural prop. You can specify the number of messages to be pluralized.

const { t } = useI18n({
  locale: 'en',
  messages: {
    en: {
      message: {
        plural: 'no bananas | {n} banana | {n} bananas'
      }
    }
  }
})

const count = ref(0)
</script>

<template>
  <i18n-t keypath="message.plural" :plural="count">
    <template #n>
      <b>{{ count }}</b>
    </template>
  </i18n-t>
</template>
