make .togglePicker function public

[rdebokx]

As part of the user experience, I want to be able to close picker modals programmatically when the user selects the next field in the form.
It seems that inside the PickerComponent, the _togglePicker function (https://github.com/MichaelCereda/react-native-form-generator/blob/master/src/lib/PickerComponent.ios.js#L53) does exactly this, but it's not accessible from outside the class.

Would it be possible to make this method publicly accessible?

mm... it's possible but it's actually an antipattern.
the react-way should be using the onChange function to set a prop on the component.

If you check the example you will notice that is possible to change the behavior of one field based on the value of another.
