Take a look at https://filamentphp.com/docs/3.x/forms/advanced#form-component-utility-injection You can do this with a closure function like

  Forms\Components\TextInput::make('code')
      ->required()
      ->maxLength(fn(Forms\Get $get):int => $get('type') == 'option_1' ? 100 : 150), // need to add the regex for this
  Forms\Components\Select::make('type')
      ->searchable()
      ->required()
      ->live()
      ->options(self::getBarcodeTypes()),

  Forms\Components\TextInput::make('code')
      ->required()
      ->maxLength(fn(Forms\Get $get):int => $get('type') == 'option_1' ? 100 : 150), // need to add the regex for this
  Forms\Components\Select::make('type')
      ->searchable()
      ->required()
      ->live()
      ->options(self::getBarcodeTypes()),
