Modal recipe

To handle forms inside React Native Modal components, check the example modal form.

This is the case, where a simple form is placed inside a modal. When the keyboard is visible, the only tasks are to push the input (if needed) above the keyboard and make the submit button visible, when scrolling to the bottom.
