Repeater Index

Is it possible to get the index value in a repeater? I want to set a field based on the index. something like:

Repeater::make('addresses')
->relationship()
->minItems(1)
->maxItems(2)
->schema([
    Select::make('billing_or_delivery')
        ->required()
        ->options([
            'Delivery' => 'Delivery',
            'Billing' => 'Billing',
        ])
        ->default($index ? 'Delivery' : 'Billing')
....

Repeater::make('addresses')
->relationship()
->minItems(1)
->maxItems(2)
->schema([
    Select::make('billing_or_delivery')
        ->required()
        ->options([
            'Delivery' => 'Delivery',
            'Billing' => 'Billing',
        ])
        ->default($index ? 'Delivery' : 'Billing')
....

I'm not sure if there is a simple solution to this... you may need to extend the Repeater component

This isn't an exact solution to what you are looking for but something similar could be done. I wanted a repeater that used the index in the label so I overrode the getItemLabel method while extending the Repeater component.

<?php

namespace App\Forms\Components;

use Filament\Forms\Components\Repeater;
use Illuminate\Contracts\Support\Htmlable;

class IndexRepeater extends Repeater
{
    public function getItemLabel(string $uuid): string | Htmlable | null
    {   

        return $this->evaluate($this->itemLabel, [
            'state' => $this->getChildComponentContainer($uuid)->getRawState(),
            'index' => (string) array_search($uuid, array_keys($this->getState())),
            'uuid' => $uuid,
        ]);
    }

}

            'index' => (string) array_search($uuid, array_keys($this->getState())),
            'uuid' => $uuid,
        ]);
    }

}
