## zh-CN
|
|
|
|
通过 `notification.useNotification` 创建支持读取 context 的 `contextHolder`。请注意,我们推荐通过顶层注册的方式代替 `message` 静态方法,因为静态方法无法消费上下文,因而 ConfigProvider 的数据也不会生效。
|
|
|
|
## en-US
|
|
|
|
Use `notification.useNotification` to get `contextHolder` with context accessible issue. Please note that, we recommend to use top level registration instead of `notification` static method, because static method cannot consume context, and ConfigProvider data will not work.
