\Drupal calls should be avoided in classes, use dependency injection instead

I have implemented the DI. Please review.

Hi sidharth_soman

I applied your patch and it removes the dependency injection issue, but it adds an error. please see the screenshots attached.

Thank you.

Updated patch #2 by addressing #3, please review it.

Thanks & Regards,
Mrinalini

@kenyoOwen, @mrinalini9 - This issue is created solely for the implementation of the DI and its required testing. A separate ticket needs to be created for addressing the PHPCS issues once this is merged. There's no requirement to fix the 'line exceeds 80 characters' and other such issues here.
