How to conditionally import scripts per route with Flowrouter?

1 
FlowRouter.route('/marketing-hub', {
  name: "marketing_hub",
  action: function(queryParams) {
        import './ui/views/marketing-view.js';
  }
});

Something like this is not possible and throws an error Uncaught SyntaxError: Unexpected token import. How can we load files conditionally as we load a new route? I want to make sure to only load what is really needed per route.

According to the guide you can still use require as import can only be in the beginning of the file.
