passing props to shared render prop

sharedRenderProp.js

<CreateNewLocationMediaItemRP
  // pass redux dispatch and actions to the RP to receive as props
  dispatch={this.props.dispatch}
  actions={actions}

  // Use callbacks so that platform specific methods can call a function
  // in the RP.
  // The callback is a function passed from the RP to this component.
  // This enables the platform specific function this.takeNewPictureOrVideo can 
  // call a function in the RP.
  onTakeNewPicture={(callback) => {
    this.takeNewPictureOrVideo('Images', callback);
  }}
  
  // Hoist the renderProps to the top level of the function so that methods
  // can access it.
  // Use a conditional to ensure it's only done once and when the component
  // is mounted.
  render={(renderProps) => {
    if (!this.renderProps && this.state.isMounted) {
      this.renderProps = renderProps;
    }
