flatlist doesn't dislays any content - react-hooks

Good afternoon, I'm trying to make flatlist to display a number of objects from an API but for some reason, this flatlist seems not to work as I expected it to do, Wonder if anyone can find what's the issue here.
The flatlist was working properly before I import the API, because I made a custom set of data and it showed those without any issue but after I imported API like this flatlist has stopped working.
const [Accounts, setAccounts] = useState([]);
useEffect(() => {
const getDataList = async () => {
await axios
.get(
"API LINK" //I changed the API access link for security reasons but I can get log for response and Accounts in useState hook and it works properly!
)
.then((response) => {
//console.log(response.data, "loge response");
setAccounts(response.data);
})
.catch((error) => {
console.log(error, "loge error");
});
};
getDataList(); //we can put function out of the useEffect but you need to call one in order to run the function(getDataList) once in the code by useEffect.
}, []);
Flatlist code is below:
<FlatList
style={StyleSheet.container}
data={Accounts}
keyExtractor={(Accounts) => Accounts?.id}
renderItem={({ item }) => {
return (
<>
<View style={styles.container}>
<Text style={styles.items}>{item?.games}</Text>
<TouchableOpacity style={styles.price}>
<Text>{item?.price}</Text>
</TouchableOpacity>
</View>
</>
);
}}
></FlatList>
</>
I tried to get a log from Accounts and it shows all of the information that it gets from API but for some reason, without any errors, flatlist doesn't display any items.
This is a sample of the API data:
{
"id": 115,
"sellerId": 2,
"price": 105000,
"region": "2",
"isAvailable": true,
"plus": null,
"games": "Demon's Souls Digital Deluxe Edition PS5",
"view": 17,
"createdAt": "2021-02-26T11:17:10.000Z",
"sellers": {
"username": "ben"
}
},
{
"id": 116,
"sellerId": 3,
"price": 150000,
"region": "1",
"isAvailable": true,
"plus": true,
"games": "PES 2021,Assassin's Creed Valhalla ,WWE 2K20",
"view": 6,
"createdAt": "2021-02-26T11:17:11.000Z",
"sellers": {
"username": "moeindana"
}
In addition, these are the styling that currently I'm using:
const styles = StyleSheet.create({
container: {
borderRadius: 10,
borderWidth: 0.5,
borderColor: "black",
alignItems: "center",
maxWidth: "80%",
paddingTop: 20,
width: "90%",
backgroundColor: "gray",
marginLeft: 30,
marginTop: 26,
minHeight: 400,
paddingBottom: 100,
},
items: {
alignItems: "center",
maxWidth: "80%",
justifyContent: "center",
},
title: {
fontSize: 32,
},
price: {
fontSize: 15,
padding: 17,
paddingBottom: 20,
fontWeight: "bold",
borderRadius: 10,
borderColor: "black",
borderWidth: 0.5,
marginTop: 20,
top: 300,
position: "absolute",
},
}

How do I add an image to a label in AmChart5?

In data I have a am5.Picture object
icon = am5.Picture.new(root, {
height: 28,
src: src
});
The image fits on the text, is not inserted next to it
this doesn't work either
series.labels.template.set("text", "{icon} {name}") // return only name
Used Container
series.labels.values.forEach((label, index) => {
if (label.dataItem.dataContext.icon) {
let container = am5.Container.new(root, {
layout: root.horizontalLayout
})
container.children.push(label.dataItem.dataContext.icon)

I think your issue is that you are defining each marker statically within your mapview component. The function you pass to the renderMarker prop will render a marker for each marker given to the data prop of the Mapview. This will allow the package to dynamically cluster your array of markers.

How to customize or update the style of the Datagrid component?

I tried to change the header style of the Datagrid component based on material-ui style guide. Datagrid body content is updated based on custom style but the header is not reflected the custom style changes.
the code snippet is below:
export const TableStyleProp = {
style: {
color: "#ff0000"
},
selectable: true,
headerStyle: {
color: "#ff0000"
},
bodyStyle: {}
};
const muiTheme = getMuiTheme({
table: {
backgroundColor: "#FF0000 !important"
},
thead: {
backgroundColor: "#b7cbfb"
},
tableHeader: {
borderColor: "#FF0000",
backgroundColor: "#FF0000"
},
tableHeaderColumn: {
textColor: "#FF0000",
height: 56,
spacing: 24
},
tableRow: {
hoverColor: "#FF0000",
stripeColor: "#FF0000",
selectedColor: "#FF0000",
textColor: "#FF00FF",
borderColor: "#FF0000",
height: 48
},
tableRowColumn: {
height: 48,
spacing: 24
}
});

Animation - How to turn animated values into real values via interpolate

I'm trying to simultaneously restrict the values of my animation (using clamp as well as interpolate) but also get the values out of the interpolation so I can use them. Specifically because I want to update a piece of state with them and create an observable from that. I just can't figure out how to extract the 'real' value out of the AnimatedValue that is produced by the interpolation (in this case state.panValue). I've tried
this.state.panValue.value
and
this.state.panValue._value
and they come back as undefined. If anyone could help me out would be amazing!
EDIT: I'd also be really happy to just have the
this.state.pan.x
variable updated within the limits so I can skip the whole updating the state variable 'panValue' thing. A nice guy on Facebook suggested that I could implement this limit somehow inside the onPanResponderMove by switching the variable to a function or something but I've tried several things and all I get are errors, I guess because I don't really know how to 'safely' amend these animated values.
onPanResponderMove: Animated.event([
null,
{ dx: this.state.pan.x },
]),
Original Code:
import React, { Component } from 'react';
import {
View,
Animated,
PanResponder,
Text,
} from 'react-native';
import styles from './styles';
class ClockInSwitch extends Component {
constructor(props) {
super(props);
this.state = {
pan: new Animated.ValueXY(),
panValue: 0,
};
}
componentWillMount() {
this._animatedValueX = 0;
this._animatedValueY = 0;
this.state.pan.x.addListener((value) => {
this._animatedValueX = value.value;
this.setState({
panValue: this.state.pan.x.interpolate({
inputRange: [-30, 0, 120,],
outputRange: [-10, 0, 120,],
extrapolate: 'clamp',
}),
});
});
this._panResponder = PanResponder.create({
// Ask to be the responder:
onStartShouldSetPanResponder: (evt, gestureState) => true,
onStartShouldSetPanResponderCapture: (evt, gestureState) => true,
onMoveShouldSetPanResponder: (evt, gestureState) => true,
onMoveShouldSetPanResponderCapture: (evt, gestureState) => true,
onPanResponderGrant: (evt, gestureState) => {
this.state.pan.setOffset({
x: this._animatedValueX,
});
this.state.pan.setValue({ x: 0, y: 0 });
},
onPanResponderMove: Animated.event([
null,
{ dx: this.state.pan.x },
]),
onPanResponderTerminationRequest: (evt, gestureState) => true,
onPanResponderRelease: (evt, gestureState) => {
this.state.pan.flattenOffset();
Animated.timing(this.state.pan, {
toValue: 0,
duration: 500,
}).start();
},
onPanResponderTerminate: (evt, gestureState) => {
},
onShouldBlockNativeResponder: (evt, gestureState) => {
return true;
},
});
}
componentWillUnMount() {
this.state.pan.x.removeAllListeners();
}
render() {
const animatedStyle = {
transform: [{

I think this is what you're looking for. I'm using exponent so your declaration for vector icons would probably need to be changed. Cheers!

Clearing a kendo Spreadsheet but not the headers

Keno spreadsheets are new and the documentation is very scarce.
I'm trying to do something relatively simple.
I have a spreadsheet with stylized headers like this:
this.sheetsHeader = [
{
name: "ProductsEntry",
rows: [
{
height: 15,
cells: [
{
value: "Name",
bold: "true",
background: "#00435e",
textAlign: "center",
color: "white",
fontSize: 14,
}, {
value: "Type",
bold: "true",
background: "#00435e",
textAlign: "center",
color: "white",
fontSize: 14,
},
{
value: "Currency",
bold: "true",
background: "#00435e",
textAlign: "center",
color: "white",
fontSize: 14,
},
{
value: "Rate",
bold: "true",
background: "#00435e",
textAlign: "center",
color: "white",
fontSize: 14
},
{
value: "StartDate",
bold: "true",
background: "#00435e",
textAlign: "center",
color: "white",
fontSize: 14,
}
]
}
],
columns: [
{ width: 200 },
{ width: 200 },
{ width: 90 },
{ width: 90 },
{ width: 110 }
]
}
];
and that gets initialized the normal way:
$("#spreadsheet").kendoSpreadsheet({
toolbar: false,
sheetsbar: false,
sheets: that.sheetsHeader
});
Then later I have an event that clears the spreadsheet but I want to leave the headers intact.
If I do this:
var sheet = spreadsheet.activeSheet();
sheet.range(kendo.spreadsheet.SHEETREF).clear();
It wipes out the headers and leaves the sheet entirely empty.
I tried re-adding the headers in many different ways but nothing worked for me.
Aftear clearing the spreadsheet I tried:
sheet.fromJSON(that.sheetsHeader[0].rows);
I also tried deleting the sheet and re-adding it:
spreadsheet.removeSheet(0);
spreadsheet.insertSheet(that.sheetsHeader);
Nothing really worked so far and there's no documentation for this sort of scenario. Any ideas?
This did it:
sheet.fromJSON(that.sheetsHeader[0]);
I really wish they provided some documentation though. It wasn't very intuitive.
