How filament component works ?

Hi everyone!
I’m currently tinkering with a custom Filament form field and ran into a bit of confusion.
I tried the following in a Blade file:

<x-filament-forms::text-input />
@include('filament-forms::components.text-input')

<x-filament-forms::text-input />
@include('filament-forms::components.text-input')

<x-filament-forms::text-input />
@include('filament-forms::components.text-input')

<x-filament-forms::text-input />
@include('filament-forms::components.text-input')

The first line (

<x-filament-forms::text-input />

<x-filament-forms::text-input />

<x-filament-forms::text-input />

<x-filament-forms::text-input />) throws this error:

Undefined variable $getDatalistOptions

Undefined variable $getDatalistOptions

Undefined variable $getDatalistOptions

Undefined variable $getDatalistOptions
But the second line using

@include

@include

@include

@include works fine.

I thought Filament form fields are Blade components, so I’m unsure why this is happening.
Here’s the custom field I’m working on:

class NewInput extends TextInput
{
    protected string $view = 'forms.components.new-input';
}

class NewInput extends TextInput
{
    protected string $view = 'forms.components.new-input';
}

class NewInput extends TextInput
{
    protected string $view = 'forms.components.new-input';
}

class NewInput extends TextInput
{
    protected string $view = 'forms.components.new-input';
}

Can someone please explain how Filament renders these components, why this happening and what’s the correct way to use them , especially when customizing or extending?

Thanks in advance!
