Feature request: Left and Right icon element

[mohit23x]

Great library, I think it will be nice to have a functionality to supply the left and right element to the input field.

The API could be similar to react-native-paper's text input

<InputOutline
  left={<Icon />}
  right={<Icon />}
/>

may be we have to add another prop called continer-style.

Would like to hear thoughts from maintainers.
