Recharts: Change z-index of tick text, so that text shows on top of bars

You can see in the example above that the bars are on top of the text. I am currently solving for this by adjusting the opacity of the bars, but I would really like to just have the text sit on top of the bars.
I have tried using props in the Bar/tick components, as well as using the style attributes, but neither have worked.
Here is my code:
import { FaLock } from "react-icons/fa";
import {
BarChart,
Bar,
Cell,
XAxis,
YAxis,
CartesianGrid,
Tooltip,
Legend,
ResponsiveContainer,
Label,
} from "recharts";
export const MonthlyResults = ({ data }) => {
const CustomTick = (props) => {
const { x, y, payload } = props;
return (
<text
x={x + 20}
y={y + 5}
fontWeight={900}
fill="blue"
z={100}
style={{ fontSize: "1.5rem", zIndex: 100 }}
>
{payload.value.replace(/\w\S*/g, function (txt) {
return txt.charAt(0).toUpperCase() + txt.substring(1).toLowerCase();
})}{" "}
({data[payload.index].count})
</text>
);
};
return (
<div className="min-h-fit w-full justify-center bg-gray-200 rounded-md">
<h1 className="text-center text-2xl my-4 font-semibold">
Top 50 Restaurants in NYC
</h1>
<div className="h-[2000px] w-full">
<ResponsiveContainer>
<BarChart
data={data}
layout="vertical"
margin={{ top: 0, right: 0, left: -61, bottom: 0 }}
barCategoryGap="1"
>
<XAxis type="number" hide domain={[0, "dataMax"]} />
<YAxis
yAxisId={0}
type="category"
dataKey="name"
tick={<CustomTick />}
style={{
fontSize: "1rem",
fontWeight: "bold",
}}
/>
<Tooltip content={() => null} />
<Bar
dataKey="count"
onClick={(e) => {
console.log(e);
}}
style={{ zIndex: 50 }}
z={50}
>
{data.map((entry, index) => (
<Cell
cursor="pointer"
key={`cell-${index}`}
fill="rgba(112, 207, 250, 1)"
/>
))}
</Bar>
</BarChart>

Getting undeifined value when passing data from one screen to another screen in react-native

I am calling below function when user click on Login button.
Here is some lines of code that how I am trying to pass data from Login screen to MyProfile screen
Login screen
const resetTextInput = () => {
setName(null);
setPassword(null);
navigation.navigate('MyProfileScreen', { userName: name, userPwd: password,});
}
<TouchableOpacity style={styles.loginBtn} onPress={() => { resetTextInput() }}>
<Text style={styles.loginBtnTxt}>Login</Text>
</TouchableOpacity>
Here is some lines of code that how I am trying to get data from Login screen to MyProfile screen.
MyProfle screen
useEffect(() => {
console.log("username is-->",JSON.stringify(route?.params?.userName));
console.log("userpassword is-->",JSON.stringify(route?.params?.userPwd));
});
Perhaps pass route.params? as an argument inside your useEffect?
useEffect(() => {
...
},[route.params?]);
That way it'll apply the effect when you navigate into it.
Do you have a multiple stack navigator? If you are at different stack navigator and you want to pass params to a screen from different stack navigator, you have to specify the screen.
For example you are at the AuthStack and you want to navigate to MyProfileScreen from the ProfileStack:
navigation.navigate('ProfileStack', { screen: 'MyProfileScreen', params: { //data here } });
if not, I think you got a typo in your BottomTab component. Change the name of the first tab from "MayProfileScreen" to "MyProfileScreen".
then use this to navigate:
navigation.navigate('MyProfileScreen', { //params here });

Good Day Every one! i just want to ask for your opinion why does my code display the error at the title. I've been working on it for 2 days but haven't resolve it yet. I hope somebody will help me. Thank you! Here is my actual Code. I'm using cloudinary where i save the image (which works perfectly) and firestore as my database. the error occurs when I apply Insert function on firestore for database.

The return should have your JSX code in it to return Something.
Your current return has JSX code but it is all under your AddPost class while your App function has nothing to return.
You are using useState which is used for functional components and setState which is used for class components combined. I suggest you should use only one type of component at a time in a project to make your code simpler and better.
To make this work I suggest you should add your AddPost class under App's return.
eg
const App = (props) => {
//somewhere here
return(
//only if this is your initial file
//else import other file and write followingly
<AddPost/>
)
export default App;

react native: animation not triggering in release mode

I am trying my react native app on android and iOS using the release mode. unfortunately, there is an animation that doesn't trigger in release mode which works perfectly on debug mode.

in Dashboard.js, i have a headerLeft that should trigger the function handleThis() which doesn't seems to be doing. however, when pressed, the TouchableOpacity component stay 'selected' rather than coming back to its original state.
any suggestion?
thanks
EDIT:
the issue occurs at any time when the debugger is not on. sorry i just discovered it right now. The animation works perfectly if the remote JS debugger is launched.
So, i thought the issue may be the processing time, as the app is working slower when the debugger is on, maybe my handleThis() function was not loaded...
So, I moved the setParams() from the ComponentDidMount to WillMount.
didn't worked :\
Any suggestion?

Why is react-native-material-dropdown so slow in the way I use it to edit and add majors?

My app drop-downs are pretty slow. It especially takes a long time if i go into the Settings Screen and try to change my major. Or anything dealing with adding or editing a major in this specific screen. I really need to make adding or editing a major much faster. I am not sure the reason why editing or adding a major is taking too long. And I am not sure about how to go at making adding and editing a major much faster. So I am posting the entire component and I am commenting parts that deal with adding or editing a major. I am using react-native-material-dropdown.
Here is the entire component code:
