 **适配指导**
 
 当事件参数设置为undefined，将会禁用该事件，依据实际应用开发场景进行参数设置即可。

+
+## cl.arkui.2 @Prop/@BuilderParam 状态变量需要初始化或从父组件传值
+
+**示例：**
+
+```ts
+// xxx.ets
+@Entry
+@Component
+struct Parent {
+  @State message: string = 'Parent'
+  build() {
+    Column() {
+      Child()   // 编译报错
+    }
+  }
+}
+
+@Component
+struct Child {
+  @Prop message: string
+  build() {
+    Column() {
+      
+    }
+  }
+}
+```
+
+**变更影响**
+
+当@Prop/@BuilderParam 状态变量未初始化且未从父组件传值时，编译无法通过。
+
+
+**关键的接口/组件变更**
+
+不涉及。
+
+**适配指导**
+
+对@Prop/@BuilderParam 状态变量做初始化赋值或从父组件调用子组件时传入。
+
+
+## cl.arkui.3 @BuilderParam 状态变量初始化赋值必须为@Builder函数/方法
+
+**示例：**
+
+```ts
+// xxx.ets
+@Builder
+function builderFunction() {
+  Text('Hello Builder')
+}
+
+function normal () {
+
+}
+
+@Component
+struct Index {
+  @BuilderParam builderParam: ()=>void = builderFunction
+  @BuilderParam builderParam2: ()=>void = normal   // 编译报错
+  build() {
+    Column() {
+
+    }
+  }
+}
+```
+
+**变更影响**
+
+@BuilderParam 状态变量初始化赋值非@Builder方法时，编译无法通过。
+
+
+**关键的接口/组件变更**
+
+不涉及。
+
+**适配指导**
+
+@BuilderParam 状态变量初始化赋值传入@Builder方法。
