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)} /> </>; };
