[symfony component debug exception fatalthrowableerror] call to undefined method illuminate\foundation\application::share()

Hello, I just tried to install reportico by this command "composer require reportico/laravel-reportico "~5.2"". Once i add this line "Reportico\Reportico\ReporticoServiceProvider::class," to my config/app.php, I get the following error message: FatalThrowableError in ReporticoServiceProvider.php line 130: Call to undefined method Illuminate\Foundation\Application::share()

Any ideas why? Thank you in advance!
