  rtl: true,
  prefixCls: 'my-message',

FAQ

Why I can not access context, redux, ConfigProvider locale/prefixCls in message?

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

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

const [api, contextHolder] = message.useMessage();

return (
  <Context1.Provider value="Ant">
    {/* contextHolder is inside Context1 which means api will get value of Context1 */}
    {contextHolder}
    <Context2.Provider value="Design">
      {/* contextHolder is outside Context2 which means api will **not** get value 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.
