ForwardRef error with typescript and react-native

According to the definitions:

function forwardRef<T, P = {}>(Component: RefForwardingComponent<T, P>): ComponentType<P & ClassAttributes<T>>;
interface RefForwardingComponent<T, P = {}> {
    (props: P & { children?: ReactNode }, ref?: Ref<T>): ReactElement<any> | null;
    propTypes?: ValidationMap<P>;
    contextTypes?: ValidationMap<any>;
    defaultProps?: Partial<P>;
    displayName?: string;
}

ref is an optional argument, try the following:

Inside a class create a ref object with a type parameter equal to your desired target (in my case div but View also works in react-native)

private divRef: React.RefObject<div> = React.createRef();

In the interface that represents the props for the forwarded component expose it as an optional property

interface Props {
  ref?: React.RefObject<div>;
}

Declare the forwarded component with the type React.ComponentType

const ComponentWithForwardedRef: React.ComponentType<Props> = 
  React.forwardRef((props: Props, ref?: React.Ref<div>) => (
    <div ref={ref}>{props.message}</div>
  ));

When an instance of the component with the forwarded ref is created send the created ref object as a prop

<ComponentWithForwardedRef ref={this.divRef} />

All in one:

import * as React from "react";
import { render } from "react-dom";

interface Props {
  message: string;
  ref?: React.RefObject<div>;
}

const ComponentWithForwardedRef: React.ComponentType<Props> = 
  React.forwardRef((props: Props, ref?: React.Ref<div>) => (
    <div ref={ref}>{props.message}</div>
  ));

class App extends React.Component<Props> {
  private divRef: React.RefObject<div> = React.createRef();

  public componentDidMount() {
    const div = this.divRef.current;
    // check the console!
    console.log(div);
  }

  public render() {
    return (
      <ComponentWithForwardedRef ref={this.divRef} {...this.props} />
    )
  }
}

render(<App message="hello world" />, document.getElementById("root"));
