HarmonyOS 鸿蒙Next builder全局构建函数 应该写在哪里 才可以让整个应用都能调取

在前面加个export导出就行了

src/main/ets/view/MyBuilder.ets

[@Builder](/user/Builder)
export function MyGlobalBuilderFunction(){
  Text('哈哈')
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

src/main/ets/pages/Page20.ets

import { MyGlobalBuilderFunction } from '../view/MyBuilder'
@Entry
@Component
struct Page20 {
build() {
Column() {
MyGlobalBuilderFunction()
}.width(100).height(100)
}
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

//导出组件
