Use `message.useMessage` to get `contextHolder` with context accessible issue.

|
|
```jsx
|
||
|
|
import { message, Button } from 'antd';
|
||
|
|
|
||
|
|
const Context = React.createContext({ name: 'Default' });
|
||
|
|
|
||
|
|
function Demo() {
|
||
|
|
const [messsageApi, contextHolder] = message.useMessage();
|
||
|
|
const info = () => {
|
||
|
|
messsageApi.open({
|
||
|
|
type: 'info',
|
||
|
|
content: <Context.Consumer>{({ name }) => `Hello, ${name}!`}</Context.Consumer>,
|
||
|
|
duration: 1,
|
||
|
|
});
|
||
|
|
};
|
||
|
|
|
||
|
|
return (
|
||
|
|
<Context.Provider value={{ name: 'Ant Design' }}>
|
||
|
|
{contextHolder}
|
||
|
|
<Button type="primary" onClick={info}>
|
||
|
|
Display normal message
|
||
|
|
</Button>
|
||
|
|
</Context.Provider>
|
||
|
|
);
|
||
|
|
}
|
||
|
|
|
||
|
|
ReactDOM.render(<Demo />, mountNode);

```
