Support for React Native's SyntheticEvent type

[JorensM]

Feature request

The Formik docs say that Formik is 100% compatible with React Native, but this is slightly untrue if you're using TypeScript. Formik's functions don't accept React Native's event type NativeSyntheticEvent, and the structure of the event is also slightly different and the value of the change is stored elsewhere, so I'm not even sure if Formik supports NativeSyntheticEvent. Because of this I have to convert my event to ChangeEvents before I can pass them to Formik's functions.

Current Behavior

NativeSyntheticEvent not supported.

Desired Behavior

NativeSyntheticEvent to be supported

Suggested Solution

Have all Formik functions that accept an event also be able to accept and handle NativeSyntheticEvent

Who does this impact? Who is this for?

This impacts developers who use Formik with Typescript+React Native

Describe alternatives you've considered

Current alternative is to convert the NativeSyntheticEvent to a ChangeEvent before passing it to the Formik function
