Hey thanks for making the great library! Is there a status update on this item? Specifically I am interested in the trailingIcon. Do you need someone from the community to pick this up?

What's the status for add leading and trailing icon in text input of react-native-paper?

[Raunak-Agrawal]

Any update on this? It would be useful it would add trailing icon at the end. I was trying to add password field and I needed that eye icon to hide/show password.

Waiting for this!
