Document method to call on refs #419

Open
@cem2ran

Description

Bringing this over from Discord as requested by @MoOx. I'm basically not sure if this is the right way to use refs and if the external I've defined in the following example should be exposed in the repo:

open ReactNative;
open ReactNavigation;
// TODO: add to TextInput?
external elementToObj: TextInput.element => Js.t({..}) = "%identity";
[@react.component]
let make = (~navigation: Navigation.t) => {
 open Navigation;
 let (text, onChangeText) = React.useState(() => "Home");
 let ref = React.useRef(Js.Nullable.null);
 React.useEffect0(() => {
 let intervalId =
 Js.Global.setTimeout(
 () =>
 switch (ref->React.Ref.current->Js.Nullable.toOption) {
 | Some(_ref) => _ref->elementToObj##focus()
 | None => ()
 },
 5000,
 );
 Some(() => Js.Global.clearTimeout(intervalId));
 });
 <>
 <TouchableOpacity
 onPress={_ => navigation->Navigation.navigate("PrivacyPolicy")}>
 <Text> {React.string(text)} </Text>
 </TouchableOpacity>
 <TextInput ref onChangeText={text => onChangeText(_ => text)} />
 </>;
};
