Session Destroy and Flashdata

When I execute a 

Code:

$session->destroy();
$session->setFlashdata('msg', 'Hello');
return()->redirect()->to('/');

The flash data is not available on the redirected page. Why?

Simpler is always better

Because you desroyed the session you need to recreate the session again first.

What did you Try? What did you Get? What did you Expect?

OK, I get it. It's not created again until the constructor of the redirected page is executed.

But my redirect's page controller creates the session in the constructor.

You must start the session BEFORE setFlashdata, not from your redirected page, because at this time there is no session.

just add session_start() right after destroying it (and before setFlashdata())
