react-native-numeric-input change event is not triggered - react-native

I'm currently working on a react project using multiple libraries including react-native-numeric-input which for some reason have a lot of unexpected behaviours.
Last night I had everything working as it should be but when I can to take another look the numeric input + and - buttons are not responding to any of the clicks, I even added a console.log to the onChange prop to test if the value is not changing or the event is not triggered and i didn't get anything.
this the numeric input:
<NumericInput
onChange={num => {
console.log(num);
this.setState({ updateItem: num}, this.saveChangedConfigs);
console.log('input', this.state);
}}
value={this.state.updateItem}
totalWidth={configValues.inw}
totalHeight={configValues.inh}
initValue={this.state.updateItem}
inputStyle={{ backgroundColor: '#f4f4f4'}}
containerStyle={styles.updateValue}
minValue={1}
/>
these are the two methods that change the state:
saveChangedConfigs = async () => {
try {
this.props.saveConfigs({
stockpile: this.state.updateItem.toString(),
data: this.state.updateData.toString(),
delete: this.state.emptyFiles.toString(),
autoUpdate: this.state.autoUpdate.toString(),
language: this.state.language
})
await this.initConfigs();
} catch (error) {
console.log('save err', error);
}
}
and
initConfigs = async () => {
const configs = await AsyncStorage.multiGet([
'updateStockpile',
'updateData',
'emptyPhone',
'language',
'autoUpdate'
])
console.log("configs", configs)
const confs = {
stockpile: this.props.config.stockpile,
autoUpdate: this.props.config.autoUpdate,
language: this.props.config.language,
data: this.props.config.data,
delete: this.props.config.delete
}
await configs.map(conf => {
switch(conf[0]){
case 'updateStockpile': if(conf[1] !== null) confs.stockpile = conf[1]; break;
case 'updateData': if(conf[1] !== null) confs.data = conf[1]; break;
case 'emptyPhone': if(conf[1] !== null) confs.delete = conf[1]; break;
case 'language': if(conf[1] !== null) confs.language = conf[1]; break;
case 'autoUpdate': if(conf[1] !== null) confs.autoUpdate = conf[1]; break;
}
})
await this.props.initConfigs(confs);
await this.setState({
language: confs.language,
updateItem: Number(confs.stockpile),
updateData: Number(confs.data),
emptyFiles: Number(confs.delete),
autoUpdate: confs.autoUpdate
});
}
this is my initial state:
this.state = {
language: this.props.config.language,
updateItem: Number(this.props.config.stockpile),
updateData: Number(this.props.config.data),
emptyFiles: Number(this.props.config.delete),
autoUpdate: this.props.config.autoUpdate
}
Hope you guys can help me out with this or maybe suggest an alternative if you know about one.

In React-native i'm using 'sharingan-rn-modal-dropdown'; Dropdown in form for add and edit data but selected values not getting reflected in dropdown

what exactly is happening is when i select the delivery service onChangeService i'm setting the next dropdown i.e. carrier's list.Also i'm setting the selected carrier as per the service.But all the time value is getting set correctly in {this.state.selectedCarrierName} but still i can show its label only.lists contain label an value pair

Vue js - not all the data showing after store dispatch

The select box not showing sometimes the first color and sometimes not showing the first color.
How can i make it to show all the item in the select box?
I'm not getting for some reason all the promises
You can see the issue in the picture
Please help me to fix this issue i'm new to vue js
My code:
data() {
return {
propertiesTree: []
}
}
getPropertyGroups(objectId: number): void {
if (this.$data.currentObjectId === objectId)
return;
let component: any = this;
this.$data.currentObjectId = objectId;
component.showLoader();
this.$store.dispatch('properties/getPropertyGroups', objectId)
.then(({ data, status }: { data: string | Array<propertiesInterfaces.PropertyGroupDto>, status: number }) => {
// console.log(data, "data");
// console.log(status, "status")
if (status === 500) {
this.$message({
message: data as string,
type: "error"
});
}
else {
let anyData = data as any;
anyData.map(item => {
item.properties.map(prop => {
if(prop.type.toString() === 'dictionary'){
prop.dictionaryList = [];
prop.color = '';
this.getWholeDictionaryList(prop.dictionaryId.value, prop)
}
});
});
}
component.hideLoader();
});
},
getWholeDictionaryList(dictionaryId: number, prop: any){
this.$store.dispatch('dictionaries/getWholeDictionaryList', dictionaryId).then(
({ data, status }: { data: Array<any> |string , status: number }) => {
if (status === 500) {
this.$message({
message: data as string,
type: "error"
});
} else {
const arrData = data as Array<any>;
arrData.map((item,index) => {
prop.dictionaryList = [];
prop.dictionaryList = data;
this.getDictionaryItemColor(item.id.value, data, index, prop);
});
}
});
},
getDictionaryItemColor(dictionaryItemId:number, dictionaryList: Array<any>, index:number, current){
this.$store.dispatch('patterns/getDictionaryItemColor', dictionaryItemId).then((data: any, status: number) => {
if (status === 500) {
this.$message({
message: data as string,
type: "error"
});
} else{
debugger
if(current.dictionaryItemId.value === data.data.sceneObjectId)
current.color = data.data.colorString;
dictionaryList[index].color = data.data.colorString ? data.data.colorString: '#FFFFFF';
}
});
},
Html code of the select box
<el-select v-model="data.color" placeholder="Select">
<el-option
v-for="item in data.dictionaryList"
:key="item.name"
:label="item.color"
:value="item.color">
</el-option>
</el-select>
I did return to dispatch
let dispatch = this.getWholeDictionaryList(prop.dictionaryId.value, prop)
let promiseArr = [];
promiseArr.push(dispatch);
after the map closing tag i did
Promise.all(promisArr).then( () => {
debugger
this.$data.propertiesTree = anyData;
});
And I've got it solved

Issue with react-native FlatList rendering data when updating array of objects maintained in redux

I'm loading a dynamic form in a FlatList. I'm supposed to add few rows with UI elements such as TextInput, checkbox, etc. based on a condition. For example, I have a dropdown, when I select a value, I have to add a row with a button and remove that row when I select another value.
My issue is that whenever I select a value in the dropdown to add a row with button, FlatList is adding duplicate rows and they are not visible as objects in my array when I debug them. I'm using Redux to manage my application state and updating my array in reducers.
I have to display objects in my array in FlatList without any duplicates using Redux for state management.
Code:
<FlatList
key={Math.floor(Math.random())}
ref={(ref) => { this.flatListRef = ref; }}
data={this.state.mainArray}
renderItem={this._renderItem}
keyExtractor={({ item, id }) => String(id)}
extraData={this.prop}
keyboardDismissMode="on-drag"
showsVerticalScrollIndicator={false}
scrollEnabled={true}
removeClippedSubviews={false}
scrollsToTop={false}
initialNumToRender={100}
/>
componentWillReceiveProps(nextProps) {
this.setState({mainArray: nextProps.mainArray});
}
Updating array in Reducer:

// adding or removing dependency questions
let dependingQues = [];
let formArrayTemp = [...state.mainArray];
let exists;

let dependent_ques = action.item.dependentQuestionsArray[0];

Update
After researching this issue I came across this issue #24206 in GitHub. There it states:
There's a few things you aren't doing quite correctly here. Each time the render function runs you are creating a new array object for your data, so React has to rerender the entire list each time, you're renderItem function and keyExtractor function are also remade each rerender, and so the FlatList has to be rerun. You're also using the index for your key which means as soon as anything moves it will rerender everything after that point. I would recommend looking at what does/doesn't change when you rerun things (arrays, functions, object), and why the keyExtractor is important for reducing re-renders.
So I tried commenting KeyExtractor prop of FlatList and the issue got resolved. But this is causing issue in another form. How can I resolve that?

setinterval function is running infinitely

const interval = setInterval(() => {
fire.database().ref().child(getpath())
.once("value",
(snapshot) => {
let item = snapshot.val()
console.log(item)
if (item !== null) {
let array = [];
Object.
keys(item)
.forEach(i => array.push(item[i]));
setCard1(array);
}
console.log(item, "item")
if (item !== null) {
itemlen = 7 //length of object I get from valid result
//stop polling for results
console.log(itemlen, "should clear")
}
else {
console.log("polling")
}
})
}, 1000)
console.log("comingout")
if (itemlen !== 0) {
console.log("goingIn")
clearInterval(interval);
}
}, [prefVar]);
expected clearinterval to stop the setinterval function but it is running continuosly and not stopping
itemlen is getting non zero values.Is there a better way of implementing this ?
I want stop useEffect once I get valid value from db.My code inside the for setinterval selects a random path and retrieve that path only problem is that sometimes the path is empty,thus using setInterval
I would create two state items, one which keeps the interval and the other which stores itemlen, and would use another useEffect to listen on changes to itemlen, and when it is not 0, the interval should clear. Also, I would check if there is another interval running before you start another one.
const [itemlen, setItemlen] = useState(0);
const [pollingInterval, setPollingInterval] = useState(null);
useEffect(() => {
if (pollingInterval === null) {
setPollingInterval(setInterval(() => {
fire.database().ref().child(getpath())
.once("value",
(snapshot) => {
let item = snapshot.val()
console.log(item)
if (item !== null) {
let array = [];
Object.
keys(item)
.forEach(i => array.push(item[i]));
setCard1(array);
}
console.log(item, "item")
if (item !== null) {
setItemlen(7);
console.log("should clear")
} else {
console.log("polling")
}
})
}, 1000));
}
}, [prefVar]);
useEffect(() => {
if (itemlen !== 0 && pollingInterval !== null) {
clearInterval(pollingInterval);
setPollingInterval(null);
}
}, [itemlen])

can someone help me with this issue
The issue is with changeDetection for the component.
I have removed the changeDetection:ChangeDetectionStrategy.OnPush from my component its started working
