Add RegExp as feature?

[Bestfootballer]

Hi man, it's possible to add two fields for RegExps, like inputFormatters on TextField? So in this way, it's possible to manage keyboard input.

Thanks in advance.

Bye

Hello, i didn't understand very well your necessity. Do you want some RegExp formatter for input or a keyboard Event (before Change and after Change) disposed as an API to apply your regexp?
