Method flash not found in Gears\Session

[osc2nuke]

Using phpStorm i get a notice in my controller:

"Method flash not found in \Gears\Session. Referenced Method is not found in subject class"

in my controller: Session::flash('message', $product->getName() . ' added to cart'); in my View: ` @if ($flash = Session::get('message'))

×{{$flash}}

    @endif

`

But the call works: https://www.youtube.com/watch?v=WtJbyb7TgCk
