How to resize the height of the EditBox

Hello,

Goals : I want to be able to resize the height of the EditBox(iOS & Android) just like the Message app.

I used void editBoxTextChanged { getText() } for that. However, using a Japanese keyboard causes problems. There is no problem when using an English keyboard. The height of the EditBox does not change even if a line break occurs when inputting Japanese. That’s because getText() does not get when you are typing a Message with a Japanese keyboard. I am troubled. Is there any solution?

Thank you.
