FAQ

Why I can not access context, redux in notification?

antd will dynamic create React instance by ReactDOM.render when call notification methods. Whose context is different with origin code located context.

When you need context info (like ConfigProvider context), you can use notification.useNotification to get api instance and contextHolder node. And put it in your children:

const [api, contextHolder] = notification.useNotification();

return (
  <Context1.Provider value="Ant">
    {/* contextHolder is in Context1 which mean api will not get context of Context1 */}
    {contextHolder}
    <Context2.Provider value="Design">
      {/* contextHolder is out of Context2 which mean api will not get context of Context2 */}
    </Context2.Provider>
  </Context1.Provider>
);

Note: You must insert contextHolder into your children with hooks. You can use origin method if you do not need context connection.
