Modal组件里面的operation操作弹窗，能不能增加配置项backdropDismiss：点击背景关闭operation

[6oVe]

现在的modalService：

ModalSerivce.operation(actions?, platform?)

 this._modal.operation([
      { text: '标为未读', onPress: () => console.log('标为未读被点击了') },
      { text: '置顶聊天', onPress: () => console.log('置顶聊天被点击了') }
    ]);

希望修改modalService：

ModalSerivce.operation(actions?, platform?, modalOptions?)

 this._modal.operation([
      { text: '标为未读', onPress: () => console.log('标为未读被点击了') },
      { text: '置顶聊天', onPress: () => console.log('置顶聊天被点击了') }
    ],{backdropDismiss:true});

麻烦了，谢谢！
