How to use the react-with-direction/dist/constants.DIRECTIONS.LTR function in react-with-direction

function getStyleDef(direction, wrappedComponentName) {
    const currentTheme = getCurrentTheme(direction);
    let styleDef = direction === DIRECTIONS.LTR
      ? styleDefLTR
      : styleDefRTL;

    const registeredTheme = ThemedStyleSheet.get();

    // Return the existing styles if they've already been defined
    // and if the theme used to create them corresponds to the theme
    // registered with ThemedStyleSheet
    if (styleDef && currentTheme === registeredTheme) {
      return styleDef;
    }

    if (
      process.env.NODE_ENV !== 'production'
      && typeof performance !== 'undefined'
      && performance.mark !== undefined && typeof performance.clearMarks === 'function'

function getCurrentTheme(direction) {
    return direction === DIRECTIONS.LTR
      ? currentThemeLTR
      : currentThemeRTL;
  }

function getResolveMethod(direction) {
    return direction === DIRECTIONS.LTR
      ? ThemedStyleSheet.resolveLTR
      : ThemedStyleSheet.resolveRTL;
  }

if (pureComponent) {
    if (!React.PureComponent) {
      throw new ReferenceError('withStyles() pureComponent option requires React 15.3.0 or later');
    }

    return React.PureComponent;
  }

  return React.Component;
}

const contextTypes = {
  [CHANNEL]: brcastShape,
};

const defaultDirection = DIRECTIONS.LTR;
