ArkTS 中 CustomDialog 调用 dialogController.close() 偶尔无效，已确保绑定正确并在 onDisappear 释放资源，仍未解决，是什么原因？

确保 DialogController 绑定正确，close() 仍无效
在 onDisappear 里手动释放，未能解决
尝试 setTimeout(() => dialogController.close(), 0) 但效果不稳定

Answer 1

demo如下：
@CustomDialog
struct CustomDialogExample {
cancel?: () => void
confirm?: () => void
controller: CustomDialogController

build() {
Column() {
Text('我是内容').fontSize(20).margin({ top: 10, bottom: 10 })
Flex({ justifyContent: FlexAlign.SpaceAround }) {
Button('cancel')
.onClick(() => {
this.controller.close()
if (this.cancel) {
this.cancel()
}
}).backgroundColor(0xffffff).fontColor(Color.Black)
Button('confirm')
.onClick(() => {
this.controller.close()
if (this.confirm) {
this.confirm()
}
}).backgroundColor(0xffffff).fontColor(Color.Red)
}.margin({ bottom: 10 })
}
}
}

@Entry
@Component
struct CustomDialogUser {
dialogController: CustomDialogController = new CustomDialogController({
builder: CustomDialogExample({
cancel: this.onCancel,
confirm: this.onAccept,
}),
})

onCancel() {
console.info('Callback when the first button is clicked')
}

onAccept() {
console.info('Callback when the second button is clicked')
}

build() {
Column() {
Button('click me')
.onClick(() => {
this.dialogController.open()
})
}.width('100%').margin({ top: 5 })
}
}
