callback: (element: Element) => {
    // This share API is based off https://facebook.github.io/react-native/docs/0.52/share
    const dialogTitle: ?DOMString = element.getAttributeNS(
      Namespaces.SHARE,
      'dialog-title',

    const message: ?DOMString = element.getAttributeNS(
      Namespaces.SHARE,

      'subject',
    );
    const title: ?DOMString = element.getAttributeNS(Namespaces.SHARE, 'title');
    const url: ?DOMString = element.getAttributeNS(Namespaces.SHARE, 'url');

    const content = getContent(message, title, url);
    if (content) {
      const options = getOptions(dialogTitle, subject);
