How to use the react-redux-firebase/lib/helpers.isLoaded function in react-redux-firebase

propNames.some(propNames, name => {
        const propValue = get(props, name)
        return (
          isLoaded(propValue) &&
          (isEmpty(propValue) ||
            (Array.isArray(propValue) && !Object.keys(propValue).length))
        )
      }),
    component

    some(propNames, name => !isLoaded(get(props, name)))
  )

  return spinnerWhile(props => some(propNames, name => !isLoaded(props[name])))
}

some(propsNames, name => {
        const propValue = get(props, name)
        return (
          isLoaded(propValue) &&
          (isEmpty(propValue) || (isArray(propValue) && !size(propValue)))
        )
      }),
    component

some(propsNames, name => {
        const propValue = get(props, name)
        return (

        )
      }),
    component

    propNames.some(name => !isLoaded(get(props, name)))
  )

(projectEvents, displayNames) => {
    if (!isLoaded(projectEvents)) {
      return projectEvents
