How to format dependable, readonly(calculated) fields?

I have a form with 3 TextInput fields: * amount (user enters value here) * price (comes from db) * sum (calculated field/value)

Forms\Components\TextInput::make('amount')
    ->numeric()
    ->reactive()
    ->afterStateUpdated(function (callable $set, callable $get, $state) {
        $this->calculate($set, $get);
    })
    ->required(),
Forms\Components\TextInput::make('price')
    ->extraInputAttributes(['readonly' => true]),
Forms\Components\TextInput::make('sum')
    ->extraInputAttributes(['readonly' => true]),

Forms\Components\TextInput::make('amount')
    ->numeric()
    ->reactive()
    ->afterStateUpdated(function (callable $set, callable $get, $state) {
        $this->calculate($set, $get);
    })
    ->required(),
Forms\Components\TextInput::make('price')
    ->extraInputAttributes(['readonly' => true]),
Forms\Components\TextInput::make('sum')
    ->extraInputAttributes(['readonly' => true]),

I can use Mask for amount field but how can i format read-only fields price and sum?

$this->calculate i am unsure what you are doing in this with the getters and setters. But you would tend to set it. You can add ->disabled() I do believe to make them readonly.

Hi, do you mind to share the tricks how you to populate the sum

Looks like it's done with $this->Calculate and passing the settings and getters so will be setting the sum in the calculate formation. Only updates on changing the amount.

 public function calculate(callable $set, callable $get) {
    $amount = floatval($get('amount'));
    $price = floatval($get('price'));
    $sum = $price * $amount;
    $set('sum', $this->formatNumber($sum));
}
