How to make a notification about the execution of the POST method at the controller level?

Question

Laravel

Good afternoon, ladies and gentlemen.
There is a feedback form.
Which is processed in the controller.
I would like to make a notification about successful sending before the redirect.

public function postContact(Request $request) {
        $this->validate($request, [
            'email' => 'required|email',
            'subject' => 'min:3',
            'message' => 'min:10',
            'infoaboutsender' => 'min:6']);

        $data = array(
            'email' => $request->email,
            'subject' => $request->subject,
            'bodyMessage' => $request->message,
            'infoaboutsender' => $request->infoaboutsender
        );

        Mail::send('includes.contactemail', $data, function($message) use ($data){
            $message->from($data['email']);
            $message->to('[email protected]');
            $message->subject($data['subject']);
        });

        Session::flash('success', 'Your Email was Sent!');
        // Хочу реализовать тут


        return redirect('/');

Answer 1

Well, at least there is: laracasts / flash
Which can be implemented once and for a long time, and then used in such cases:

Flash::success( 'Оплата прошла успешно.' );

return redirect( '' );
