Mapping over an array in javascript to render data dynamically

I have an array of items which I have retrieved from an Object. The array has 5 items. It looks like this:
I have saved the array in my state as :
this.state={
serviceDetails: planDetails[0].nbs_plans.map(service => service.extension_attributes.productServicetList.map(name=>name.name)),
}
Now, I am trying to render the array in my component using map function like :
{
this.state.serviceDetails.map((serviceName) => {
return (
<SelectableChips initialChips={serviceName} />
);
})
}
But the problem is all the arrays are coming together at the same place as shown below:
The way it should be is : The first "See more" should be at the first section, the 2nd at the 2nd and so on.
My complete code for this component looks like this:
//This is an example code for FlatList//
import React from 'react';
import {
StyleSheet, FlatList, Text, View, Alert , Image, TouchableOpacity
} from 'react-native';
import SelectableChips from '../../../components/Chip/SelectableChips';

import propTypes from 'prop-types';
import Service from './Service';
import { planDetails } from '../../../api/mockedData/PlanServiceDetails';
class Selected_Items_Array {
constructor() {
selectedItemsArray = [];
this.state = {
planName: planDetails[0].nbs_plans.map(data => data.name),
serviceDetails: planDetails[0].nbs_services.map(data => data.service_line),
};
var result = planDetails.filter(d => {
return d.nbs_plans[0].name = "TruComplete℠ Lawn Care Plan";
});
// alert(Object.keys(planDetails).length);
// alert(Object.keys(planDetails[0].nbs_plans).length);
// alert(JSON.stringify(planDetails[0].nbs_plans[0].productId));
// alert(JSON.stringify(planDetails[0].nbs_plans[0].name));
// alert(JSON.stringify(planDetails[0].nbs_plans.map(data => data.name)));
}
pushItem(option) {
selectedItemsArray.push(option);
}
getArray() {
return selectedItemsArray;
}
}

Can someone please guide me how to proceed.

As each plan has as productServicetList, create a object serviceDetails where the key is the planName and the value is productServicetList.
this.state={
serviceDetails: planDetails[0].nbs_plans.reduce(
(acc, service) => ({
...acc,
[service.name]: service.extension_attributes.productServicetList.map(
name => name.name
)
}),
{}
);
}
Then render the serviceDetail as follows
{
this.state.serviceDetails[item].map(serviceName => {
return <SelectableChips initialChips={serviceName} />;
});
}

Implemtation of Audio Progress bar in React Native

I have been trying to build a a media player in react native using Expo to be able to play audio on my music project.
I have successfully hacked one together with the preferred design but I still have a big limitation. I will love to implement a progress bar that will show how far the song has played.
Here is my player design. Secondly, How do I substitute this progress bar for IOS ??
render() {
return (
<View >
<View style={styles.container} >
<Image
style={styles.imageStyle}
source={{uri: this.state.coverName || this.MusicPlayer.getCurrentItemCover()}}
/>
<View >
<Text style = {styles.artistName}> {this.state.artistName || this.MusicPlayer.getCurrentItemArtistName()}</Text>
</View>
<View style={{paddingRight:2, paddingLeft:2}}>
<Text style={styles.songStyle}> {this.state.title || this.MusicPlayer.getCurrentSongTitle()}</Text>
</View>
<ProgressBarAndroid style={{marginLeft:10, marginRight:10}} styleAttr="Horizontal" color="#2196F3" indeterminate={false} progress={0.5} />
<View style={{flexDirection:'row', padding:10, alignItems:'center', justifyContent:'center'}}>
<Text style={styles.iconStyle2} onPress={this.playPrev}>
<Feather name="rewind" size={20} style={styles.text} />
</Text>
{this.state.playing?
<Text style={styles.iconStyle2} onPress={this.startStopPlay}>
<Feather name="pause" size={24} style={styles.text} />
</Text>
:
<Text style={styles.iconStyle2} onPress={this.startStopPlay}>
<Feather name="play-circle" size={24} style={styles.text} />
</Text>
}
<Text style={styles.iconStyle2} onPress={this.playNext}>
<Feather name="fast-forward" size={20} style={styles.text} />
</Text>
</View>
</View>
</View>
);
}
}
My Play Function
startPlay = async (index = this.index, playing = false) => {
const url = this.list[index].url;
this.index = index;
console.log(url);
// Checking if now playing music, if yes stop that
if(playing) {
await this.soundObject.stopAsync();
} else {
// Checking if item already loaded, if yes just play, else load music before play
if(this.soundObject._loaded) {
await this.soundObject.playAsync();
} else {
await this.soundObject.loadAsync(url);
await this.soundObject.playAsync();
}
}
};
My main goal is to get a small player on mobile close to this.
I am working with React native Expo version.

It works as expected but I want to render the share icon on the same row as the title text.
Can it be done?

You can use "flexDirection" to 'row' and group share icon along with the title in a view:
<View style={styles.navBar}>
<TouchableOpacity onPress={() => {Share.share(shareOptions); }}>
<View>
<Text>
<Icon color="white" name="share-alt" size={42}/>
</Text>
</View>
</TouchableOpacity>
<Text style={styles.nameHeader}>
{this.state.dataSource.title}
</Text>
</View>
add the below styling to your navBar className :
navBar: {
flex: 1,
flexDirection: 'row'
},
Also, you are using Text and a View in your TouchableOpacity which I think is not needed so I removed those and did a snack on expo similar to your code, please check it here :

React native - remove object from array

I have a Modal that displays a list of contacts. onPress, contacts are dynamically added to a View.
If a contact has already been added, on second onPress I would like to remove it from the View. For that I'm amending the state/array containing the contacts, using splice but it removes all the contacts at once.
I'm also trying to update the state of the 'Add' icon. If a contact has been added the Add icon Image should become the active one.
Not sure what I'm doing wrong?
Here's the Modal opened up:
My code:
import React, {Component} from 'react'

},
{
id: 2,
firstname: 'name2',
surname: 'surname2',

'using splice but it removes all the contacts at once.'
Because you're using splice method wrong. Check the parameters the method gets.
http://www.w3schools.com/jsref/jsref_splice.asp
[ ...this.state.contactsPicked, this.state.contactsPicked.splice(friend)]
this doesn't work as you expected as well. It merges two arrays.
var parts = ['shoulders', 'knees'];
var parts2 = ['shoulders'];
var lyrics = [ ...parts, ...parts2 ];
console.log(lyrics)
It seems you don't have to use spread operator([...arr,.arr2]),
you can simply do that
Since it re creates subs every time modal's visiblity changes and even if you change state of parent component's state it does not re render subs so you need to keep internal state for you sub components
Also your _renderAddFriendTile method was working wrong too. When
you take a look at it carefully you will realize your mistake.
Don't forget to change your icons with my test icons

You can use filter method to filter out contacts if it's already there in view.
To remove contacts from view if already added:
this.setState({
...state,
contactsPicked: this.state.contactsPicked.filter((contactsPicked,index)=> index != pickedContactsIndex)
})

Firebase.push failed: first argument contains an invalid key($$typeof)

I am learning react native for the first time for developing android app not IOS one and I was learning from Building a Simple ToDo App With React Native and Firebase tutorial from youtube.But I am getting an error while trying to add items. I get following error
