use MartinRo\FilamentCharcountField\Components\CharcountedTextarea;

class PostResource extends Resource
{
    // ...
    public static function form(Form $form): Form
    {
        return $form->schema([
            // ...
            
            // TextInput
            CharcountedTextInput::make('title')
                ->label('Title')
                ->hintIcon('heroicon-o-code')
                ->hint('Title tag in header')
                ->helperText('While Google does not specify a length for title tags, usually the first 50–60 characters are displayed.')
                ->minCharacters(50)
                ->maxCharacters(60),
                           
           // Textarea 
            CharcountedTextarea::make('description')
                ->label('Description')
                ->rows(4)
                ->hintIcon('heroicon-o-code')
                ->hint('Meta description tag in header')
                ->helperText('Meta descriptions can technically be any length, but Google generally truncates snippets to ~155-160 characters.')
                ->minCharacters(155)
                ->maxCharacters(160),
