#鸿蒙通关秘籍#问一下哈，卡片的formProvider模块有什么作用？

import { formProvider } from '@ohos.form';

export default class MyFormAbility extends FormExtensionAbility {
onUpdateForm(formId) {
const formData = formBindingData.createFormBindingData({ 'title': 'Updated Title' });
formProvider.updateForm(formId, formData);
}
}
