This may help. This is not the exact code. This code was for Store Owner.
    $todayordersCountDisplay = Order::whereIn('restaurant_id', $restaurantIds)->whereDate('created_at', Carbon::now())
    ->where('orderstatus_id', '5')->get('id')->count();
    $orderItemsCount_id = Order::whereIn('restaurant_id', $restaurantIds)->where('orderstatus_id', '5')->get('id');
    $orderItemsCount = Orderitem::whereIn('order_id', $orderItemsCount_id)->get()->count();
    $todayitemsCount_id = Order::whereIn('restaurant_id', $restaurantIds)->whereDate('created_at', Carbon::now())
    ->where('orderstatus_id', '5')->get('id');
    $todayitemsCount = Orderitem::whereIn('order_id', $todayitemsCount_id)->get()->count();
    $allCompletedOrders = Order::whereIn('restaurant_id', $restaurantIds)
        ->where('orderstatus_id', '5')
        ->get();
        $allCompletedOrderstoday = Order::whereIn('restaurant_id', $restaurantIds)
            ->where('orderstatus_id', '5')->whereDate('created_at', Carbon::now())
            ->get();
    $totalEarning = 0;
    settype($var, 'float');
    foreach ($allCompletedOrders as $completedOrder) {
        $totalEarning += $completedOrder->total - ($completedOrder->delivery_charge + $completedOrder->tip_amount);
    }
    $totalEarningtoday = 0;
    settype($var, 'float');
    foreach ($allCompletedOrderstoday as $completedOrdertoday) {
        $totalEarningtoday += $completedOrdertoday->total - ($completedOrdertoday->delivery_charge + $completedOrdertoday->tip_amount);
    }
