React Hook "useToaster" cannot be called in a class component

You cannot using useToaster in class component, use rsuite.toaster instead.

Using in function component

import {
  Notification,
  useToaster,
  Placeholder,
  Uploader,
  ButtonToolbar,
  SelectPicker,
  Button
} from 'rsuite';

const App = () => {
  const [type, setType] = React.useState('info');
  const [placement, setPlacement] = React.useState('topStart');
  const toaster = useToaster();

  const message = (
    <Notification type={type} header={type} closable>
      <Placeholder.Paragraph style={{ width: 320 }} rows={3} />
      <hr />
      <Uploader action="#" />
    </Notification>
  );

  return (
    <div>
      {message}
      <hr />
      <ButtonToolbar>
        <SelectPicker
          value={type}
          data={[
            { label: 'info', value: 'info' },
            { label: 'success', value: 'success' },
            { label: 'warning', value: 'warning' },
            { label: 'error', value: 'error' }
          ]}
          onChange={setType}
          style={{ width: 200 }}
        />
        <SelectPicker
          value={placement}
          data={[
            { label: 'topStart', value: 'topStart' },
            { label: 'topCenter', value: 'topCenter' },
            { label: 'topEnd', value: 'topEnd' },
            { label: 'bottomStart', value: 'bottomStart' },
            { label: 'bottomCenter', value: 'bottomCenter' },
            { label: 'bottomEnd', value: 'bottomEnd' }
          ]}
          onChange={setPlacement}
          style={{ width: 200 }}
        />
        <Button onClick={() => toaster.push(message, { placement })}>Push</Button>
        <Button onClick={() => toaster.remove()}>Remove</Button>
        <Button onClick={() => toaster.clear()}>Clear</Button>
      </ButtonToolbar>
    </div>
  );
};

ReactDOM.render(<App />, document.getElementById('root'));

Using in class component

class AppClass extends React.Component {
  toaster;
  constructor(props) {
    super(props);
    this.state = {
      type: "info",
      placement: "topStart"
    };
  }

  componentDidMount() {
    import("rsuite").then((modules) => {
      this.toaster = modules.toaster;
    });
  }

  render() {
    const { type, placement } = this.state;
    const message = (
      <Notification type={type} header={type} closable>
        <Placeholder.Paragraph style={{ width: 320 }} rows={3} />
        <hr />
        <Uploader action="#" />
      </Notification>
    );

    return (
      <div>
        {message}
        <hr />
        <ButtonToolbar>
          <SelectPicker
            value={type}
            data={[
              { label: "info", value: "info" },
              { label: "success", value: "success" },
              { label: "warning", value: "warning" },
              { label: "error", value: "error" }
            ]}
            onChange={(e) => console.log("label", e)}
            style={{ width: 200 }}
          />
          <SelectPicker
            value={placement}
            data={[
              { label: "topStart", value: "topStart" },
              { label: "topCenter", value: "topCenter" },
              { label: "topEnd", value: "topEnd" },
              { label: "bottomStart", value: "bottomStart" },
              { label: "bottomCenter", value: "bottomCenter" },
              { label: "bottomEnd", value: "bottomEnd" }
            ]}
            onChange={(e) => console.log("placement", e)}
            style={{ width: 200 }}
          />
          <Button onClick={() => this.toaster.push(message, { placement })}>
            Push
          </Button>
          <Button onClick={() => this.toaster.remove()}>Remove</Button>
          <Button onClick={() => this.toaster.clear()}>Clear</Button>
        </ButtonToolbar>
      </div>
    );
