View Composer not working in my Laravel App - php

Question

I am trying to share variables on multiple views so i tried the view composer but it is not working as its not passing variables and is there any way to debug it
ComposerServiceProvider.php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap services.
*
* #return void
*/
public function boot()
{
view()->composer(
'layouts.admin.dashboard',
'App\Http\ViewComposers\StatComposer'
);
}
/**
* Register services.
*
* #return void
*/
public function register()
{
//
}
}
So now here will be the Composer File
StatComposer.php
<?php
namespace App\Http\ViewComposers;
use Analytics;
use Spatie\Analytics\Period;
use App\Libraries\GoogleAnalytics;
use Illuminate\Http\Request;
use Illuminate\View\View;
class StatComposer
{
/**
* Create a movie composer.
*
* #return void
*/
public function __construct()
{
$result = GoogleAnalytics::topCountries();
$country = $result->pluck('country');
$country_sessions = $result->pluck('sessions');
$topBrowsers = GoogleAnalytics::topBrowsers();
$browser = $topBrowsers->pluck('browser');
$browser_sessions = $topBrowsers->pluck('sessions');
$totalPageViews = GoogleAnalytics::fetchVisitorsAndPageViews();
$date = $totalPageViews->pluck('date');
$visitors = $totalPageViews->pluck('visitors');
$pageViews = $totalPageViews->pluck('pageViews');
}
/**
* Bind data to the view.
*
* #param View $view
* #return void
*/
public function compose(View $view)
{
$view->with('country', 'country_sessions', 'browser', 'browser_sessions','date','visitors','pageViews');
}
}
So I am unable to find way to debug it as the variables are not passing to the view i am trying to pass them to and the view is giving error of undefined variable.

The issue is your declaring a lot of variables without providing the values in the compose function. Also your not actually saving the data anywhere. It should be like this.
protected $country;
/**
* Create a movie composer.
*
* #return void
*/
public function __construct()
{
$result = GoogleAnalytics::topCountries();
$this->country = $result->pluck('country');
}
/**
* Bind data to the view.
*
* #param View $view
* #return void
*/
public function compose(View $view)
{
$view->with('country', $this->country);
}
Note we are declaring the classes property at the top, then saving to that property and then setting the 'country' variable in the with method with the $this->country property.
