Better Typescript support for Input's InputComponent when using useRef<InputComponent>

[garrettg123]

🐛 Bug Report

In order to get the proper type for creating a ref for <Input>, I currently need to import the type from import { InputComponent } from '@ui-kitten/components/ui/input/input.component'.

To Reproduce

Steps to reproduce the behavior:
const inputRef = React.useRef<InputComponent>(null)

Expected behavior

InputComponent should be exported from the @ui-kitten/components. Is this fixed in 5.x?

@garrett-gottlieb still an issue in v5. I have some ideas to make it work in a correct way so we can get rid of InputComponent using only Input, but it requires another breaking change, affecting a styled hoc.

Thinking to implement in alpha.2 for all components.

I've run into this as well. I haven't used refs much, but my workaround for it was:

import { TextInput } from 'react-native';

const inputRef = useRef<TextInput>(null);

This allows me to use the base input object to refer to.
