import { useDispatch } from "react-redux";
import { topicsLoadRequest } from "@src/actions/topics";
import { getExternalCodeSetup } from "@src/externalCode/externalRepo";
import withGlobalStyles from "@src/components/hocs/withGlobalStyles";

const hook = getExternalCodeSetup().topicsApi;
const screenName = "topics";

getExternalCodeSetup().indexScreenApiHooks.setHeaderHeight((defaultHeaderHeight, filterType, navigation) => {

   if (filterType === "topics"){
       return 300
   }

   return defaultHeaderHeight;

});

const filter = "all";
const subfilters = {
   orderby: "activity", //"meta_value", "date", "ID", "author", "title", "modified", "parent", "rand", "popular", "activity"
   order: "desc"
}

const refresh = true; //Set to true to refresh list
const searchTerm = ""

const TopicsFiltersCustom = (props) => {

   const { navigation, route, colors } = props;

   const dispatch = useDispatch();

   //If showing the matched screen, show custom filter before displaying list component
   if (route?.params?.item?.object === screenName) {

       const [tag, setTag] = useState(false);

       const handleSubmit = () => {

           //Set custom parameters before fetching
           hook.setFetchParamsFilter((props) => {

               //You can add more parameters such as "subject", "keyword" etc...

                   tag
               }
           })

           //Dispatch redux action to call api using customized filters
           dispatch(topicsLoadRequest(filter, subfilters, refresh, searchTerm));

       }

       return <View style={{ backgroundColor: colors.whiteColor, alignItems: "center", justifyContent: "center" }}>

import AppTouchableOpacity from "@src/components/AppTouchableOpacity";

export const applyCustomCode = externalCodeSetup => {

  externalCodeSetup.topicsApi.setReplyItemAvatar(props => {

    const { reply, global, isNested } = props

    return <AppTouchableOpacity
      onPress={reply.navigateToProfile ? reply.navigateToProfile : () => { }}
      style={global.avatarWrap}
    >
      <AppAvatar
        size={isNested ? 30 : 40}
        name={reply.author.fullname}
        source={{
