slimphp/Twig-View Beta add global in slim4

[FvsJ101]

Maybe someone can advise me,

I'm using Twig view beta in the new slim 4 frame work. Im also using the slim/flash package to add messages.

Now the problem is I want to create a new global so that my twig view can use the message but i keep getting the below error...

$this->container->get("view")->getEnvironment()->addGlobal('flash', $_SESSION['slimFlash']);

Unable to add global "flash" as the runtime or the extensions have already been initialized.

Can anyone advise on how to get around this or the fix for this?
