如何在Vue中通过Typescript引用组件的数据？

import { Component, Prop, Vue } from 'vue-property-decorator';

@Component
export default class ChildComponent extends Vue {
  @Prop() message!: string;
}

<template>
  <div>
    <child-component v-bind:message="parentMessage"></child-component>
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent,
  },
  data() {
    return {
      parentMessage: 'Hello from parent component',
    };
  },
};
</script>

<template>
  <div>
    <p>{{ message }}</p>
  </div>
</template>
