How to use antd.Form.create in typescript?

Question

I have a login form created by Form.create(), but I can't pass any props to this form from parent component, compiler always notify a error like

error TS2339: Property 'loading' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<Compone
nt<{}, ComponentState>> & Readonly<{ childr...'.

LoginForm.tsx

import * as React from 'react';
import { Form } from 'antd';
import { WrappedFormUtils } from 'antd/lib/form/Form';

interface Props {
    form: WrappedFormUtils;
    loading: boolean;
    username?: string;
}

class LoginForm extends React.Component<Props, {}> {
    render() {
        const { loading } = this.props;
        return (<div>form {loading ? 'true' : 'false'}</div>);
     }
}

export default Form.create()(LoginForm);

LoginPage.tsx

import LoginForm from './components/loginForm';

const loginPage: React.SFC<Props> = (props) => {
     return (
         <div>
              <LoginForm loading={true}/>
                         ^ error here!
         </div>
     );
 };

My antd version is 2.11.2

Finally I found a solution

class LoginForm extends React.Component<Props & {form:     WrappedFormUtils}, State> {
  render() {
    const { loading } = this.props;
    return (<div>form {loading ? 'true' : 'false'}</div>);
  }
}

export default Form.create<Props>()(LoginForm);

1. Import the FormComponentProps

   import {FormComponentProps} from 'antd/lib/form/Form';
   

2. Then have your component

   interface YourProps {
       test: string;
   }        
   
   class YourComponent extends React.Component<YourProps & FormComponentProps> {
       constructor(props: YourProps & FormComponentProps) {
           super(props);
           ...
       }
   }
   

3. Then export the class using Form.create()

   export default Form.create<YourProps>()(YourComponent);
   

   The generic argument on Form.create casts the result to a React ComponentClass with YourProps - without FormComponentProps, because these are being injected through the Form.create wrapper component.
