有没有办法改变laracast闪光的生命时间？

I want to change the time a flash notification is shown.

I have a working laracast flash and that is fine, but the flash coveres about 1/4 of the screen, so I only want it forabout 2sek and not like 10sek as it is now. I don't know where to start. Is there such a function?

This is the flash

if ( ! function_exists('flash')) {

    /**
     * Arrange for a flash message.
     *
     * @param  string|null $message
     * @param  string      $level
     * @return \Laracasts\Flash\FlashNotifier
     */
    function flash($message = null, $level = 'info')
    {
        $notifier = app('flash');

        if ( ! is_null($message)) {
            return $notifier->message($message, $level);
        }

        return $notifier;
    } 

}

This is where it is called

if ($cartItem->save()) {
            flash(trans( 'alerts.cart_added'), 'success')->important();

return back();

There is a simple example in the GitHub page of the package Hiding Flash Message

From the document,

Write a simple bit of JavaScript. For example, using jQuery, you might add the following snippet just before the closing tag.

<script> $('div.alert').not('.alert-important').delay(3000).fadeOut(350); </script>

This will find any alerts - excluding the important ones, which should remain until manually closed by the user - wait three seconds, and then fade them out.

So for your case you just need to only target the specific important class like:

(if you are using jQuery)

$('.alert-important').delay(3000).fadeOut(350);
