Attribute [livewire] does not exist.

                
                        If you are using a recent install of Laravel 8,
you will have Livewire V2.
In this version, Route::livewire() romeved.
 Instead, you specify a normal get() route,
 with the action being the Livewire component class.
 
 
 Route::get('/' , App\Http\Livewire\LandingPage::class);
