Planning to buy FluentCart: Quick question about custom fields and conditional checkout

I am very interested in purchasing FluentCart and diving into the ecosystem, but I have one important question before making the move.

Is adding custom fields to the checkout (such as text, number, file upload, checkboxes, radio buttons, etc.) along with conditional visibility logic something that can be handled natively directly inside FluentCart, or is it necessary to integrate it with FluentForms (or use custom code/workarounds)?

Coming from WooCommerce, relying on external third-party plugins just to add clean custom and conditional fields to the checkout has always been a major pain point. I'd love to know what the recommended, optimal approach is within the WPManageNinja ecosystem to handle this nowadays in FluentCart.

Thanks in advance for any insights or best practices you can share!
