This tutorial covered some initial steps in displaying different flash message styles in your Laravel 5 apps.

First Step: Creating Flash Message in the Controller

public function store(OfficeRequest $request)
{
    Office::create($request->all());

    \Session::flash('flash_message','Office successfully added.'); //<--FLASH MESSAGE

    return redirect('offices');
}

public function store(OfficeRequest $request)
{
    Office::create($request->all());

    \Session::flash('flash_message','Office successfully added.'); //<--FLASH MESSAGE

    return redirect('offices');
}
\Session::flash(“name_of_your_flash”, “message_to_display”)

is a method used by Laravel to store your flesh temp message. Add this code inside any function in your Controller, where you want to display a Flash Message. Make sure you place your session after the save/create method.
