Calculated state in RepeatableEntry

How can we help you?

In this example of filament docs, we can multiply record amount and vat_rate:

Infolists\Components\TextEntry::make('amount_including_vat')
    ->state(function (Model $record): float {
        return $record->amount * (1 + $record->vat_rate);
})

Ref: https://filamentphp.com/docs/3.x/infolists/entries/getting-started#calculated-state

But in my project, the TextEntry is in a RepeatableEntry. I have multiple products of value and quantity, and I want to display the total price per product row. I cannot get this to work...

Infolists\Components\RepeatableEntry::make('products')->schema([
    Infolists\Components\TextEntry::make('value')
        ->money('EUR'),
    Infolists\Components\TextEntry::make('quantity'),
    Infolists\Components\TextEntry::make('total') // value * quantity
        ->money('EUR')
        // 1
        ->state(function($record) {
            // $record returns record, but not the repeated row??
        })
        // 2
        ->state(function(Infolists\Components\TextEntry $textEntry) {
            // $textEntry returns this field, and via ->getContainer() I can access the row
            $textEntry->getContainer()->getComponents()[0] //value field
            $textEntry->getContainer()->getComponents()[1] //quantity field
            // ... but this doesn't feel right, because, what if I change the order of fields? And furthermore, this doesn't feel as readable as filament intended, I think...
        }),
])

I can't find any documentation on how to achieve this. I would also be helped if there is somewhere a list of parameters that I can use in the state() function.
