Vuetify:如何收听对话的关闭事件？

<template>
  <v-dialog v-model="dialogOpen" @input="onDialogClose">
    <v-card>
      <v-card-title>
        <span class="headline">对话框标题</span>
      </v-card-title>
      <v-card-text>
        对话框内容
      </v-card-text>
      <v-card-actions>
        <v-btn color="primary" @click="dialogOpen = false">关闭</v-btn>
      </v-card-actions>
    </v-card>
  </v-dialog>
</template>

<script>
export default {
  data() {
    return {
      dialogOpen: false
    };
  },
  methods: {
    onDialogClose(value) {
      // 在这里处理对话框关闭事件
      console.log('对话框关闭');
    }
  }
};
</script>
