java.lang.ClassCastException: uni.UNIDBEF90B.GenPagesCreatePicker

在文档 https://doc.dcloud.net.cn/uni-app-x/vue/data-bind.html#defineexpose

<script setup lang="uts">  
const fooRef = ref<DefineExposeFooComponentPublicInstance | null>(null)  
const fooStr = ref('')  
const fooNum = ref<number>(0)

DefineExposeFooComponentPublicInstance 在哪里定义的？在安卓编译时报错。

下面是我定义的type

    type TPickerExpose = { setPickerVisible: (s: boolean) => void }  
    const pickerUvueRef = ref<TPickerExpose | null>(null);
