Make Form Component Utility Injection Can be Called from Custom Method

I got custom form field with several custom methods in it, i want to access utility injections ($get, $set, etc.) on my custom methods. i tried

MyCustomForm::make('name')
->myCustomMethod(fn(callable $get) => $get('other_name'))

MyCustomForm::make('name')
->myCustomMethod(fn(callable $get) => $get('other_name'))

but got error that paramater $get is not passed.

Solution:

Also you need to call $this->evaluate() to evaluate your closure. Have a look at the Filament source code to see how it works.

use Filament\Forms\Get;

MyCustomForm::make('name')
->myCustomMethod(fn(Get $get) => $get('other_name'))

use Filament\Forms\Get;

MyCustomForm::make('name')
->myCustomMethod(fn(Get $get) => $get('other_name'))

if you're using custom method then you need to use Filament\Support\Concerns\EvaluatesClosures
