withNavigation

withNavigation is a higher order component which passes the navigation prop into a wrapped component. It's useful when you cannot pass the navigation prop into the component directly, or don't want to pass it in case of a deeply nested child.

• withNavigation(Component) returns a Component.

Example

import React from 'react';
import { Button } from 'react-native';
import { withNavigation } from 'react-navigation';

class MyBackButton extends React.Component {
  render() {
    return (
      <Button
        title="Back"
        onPress={() => {
          this.props.navigation.goBack();
        }}
      />
    );
  }
}

// withNavigation returns a component that wraps MyBackButton and passes in the
// navigation prop
export default withNavigation(MyBackButton);

Notes

• If you wish to use the ref prop on the wrapped component, you must pass the onRef prop instead. For example,

// MyBackButton.ts
export default withNavigation(MyBackButton);

// MyNavBar.ts
<MyBackButton onRef={elem => (this.backButton = elem)} />;
