How do I get count()?

[atach]

I am trying to get the total count() before I apply get(), but it gives an error.

$returnData = $this->trainerSlot
            ->orderBy('date')
            ->orderBy('place_id')
            ->offset(0)->limit(25);
        $allCount = $returnData->count(); // Error

If I use the same construction without a repository it works.

$returnData = TrainerSlot::orderBy('date')
            ->orderBy('place_id')
            ->offset(0)->limit(25);
$allCount = $returnData->count(); // find total 1200 string

If I try to get the total amount after, I called $returnData->get(), then it only gives out the amount received after the limit&offset.

$returnData = $this->trainerSlot
            ->orderBy('date')
            ->orderBy('place_id')
            ->offset(0)->limit(25);
$returnData->get();
$allCount = $returnData->count(); // find total 25 string
