How to have multiple Flatlists with filtered data in React Native

hope this fix your issue You just need to modify your onRenderItem function to render some specific objects as below (this Flatlist shows only inProgress objects):
code :
onRenderItem = ({ item }) => {
  if (item.type === 'inProgress') {
    return (
      <TouchableOpacity onPress={this.showAlert}>
        <Text style={styles.listStyle}>
          { item.goal } { item.key }
        </Text>
      </TouchableOpacity>
    )
  } else { return null; }
};

how to show filtered JSON data from two different key values in react native

hop of those help? Try this solution. Iterate over profiles with Array#map and for each item create a new object, which is consisted from the profile itself and on the posts filter the appropriate posts using Array#filter. And then show this data in your React code.
Javascript example.
code :
const data = {
  "profile": [
    {
      "proid": {
        "user": "kohinoor"
      },
      "image": "/media/profiles/DSCN3253.JPG",
      "shoptype": "Clothes",
      "city": "Ahemednagar"
    },
    {
      "proid": {
        "user": "shrawani"
      },
      "image": "/media/profiles/PicsArt_08-17-09.24.48_qA94ILU.jpg",
      "shoptype": "Cat Shop",
      "city": "Kopargaon"
    },
    {
      "proid": {
        "user": "rajpal"
      },
      "image": "/media/profiles/PicsArt_08-17-09.24.48_T3birjf.jpg",
      "shoptype": "Clothings",
      "city": "Sangamner"
    },
  ],
  "post": [
    {
      "id": 120,
      "content": "Old Mi Stocks or Sell !!!",
      "url": null,
      "shareproductdealer": "kohinoor",
      "shareproducttype": "Xiaomi Mi",
      "shareproductid": "68",
      "username": "kohinoor",
      "updated": "2017-09-08T10:49:11Z",
      "timestamp": "2017-09-08T10:49:11Z"
    },
    {
      "id": 119,
      "content": "Hello... Miahe...",
      "url": null,
      "shareproductdealer": null,
      "shareproducttype": null,
      "shareproductid": null,
      "username": "shrawani",
      "updated": "2017-09-08T10:38:14Z",
      "timestamp": "2017-09-08T10:38:14Z"
    },
    {
      "id": 115,
      "content": "hello jockey",
      "url": null,
      "shareproductdealer": "rajpal",
      "shareproducttype": "jockey",
      "shareproductid": "65",
      "username": "rajpal",
      "updated": "2017-08-16T11:22:32Z",
      "timestamp": "2017-08-16T11:22:32Z"
    }
  ]
};

const profiles = data.profile;
const posts = data.post;

const profilePosts = profiles.map(item => ({
  profile: item,
  post: posts.filter(post => post.username === item.proid.user)
}));

console.log(profilePosts);

may help you . I am creating a flat list with checkbox and text,but i am going to selecting a single item it selects all the items from the list, and i want to select single or multiple or all items but not all like this, when i selecting single item it checks true to all items. Here i am fetching list from api. Here is my Code :
code :
export default class AllLists extends Component {

constructor(props){
    super(props)
    this.state={
        isChecked : [],
}
}

componentWillMount = () => {
    let initialCheck = this.state.lists.map(() => false);
    this.setState({isChecked : initialCheck})
}

getAllList = () => {
 this.showRefreshLoader();
    getSessionId().then(sessionId => {
        showMyLists(sessionId).then(response => {
            onSuccess(response).then(successResponse => {
            this.hideRefreshLoader();
            this.setState({
                lists:successResponse,
            })
        })
    }).catch(error => {
        this.hideRefreshLoader();
        onFailure(error).then(errorMessage => {
            showMessage(errorMessage);
        })
      })
    })
}

//add product to selected lists 
addProduct = () => {

    showMessage(JSON.stringify(this.state.selectedLists))
    getSessionId().then(sessionId => {
        addProductToLists(sessionId,this.state.selectedLists,
    this.props.productId).then(response => {
            onSuccess(response).then(response => {
                alert(JSON.stringify(response.message))
            })
        }).catch(error => {
            onFailure(error).then(error => {
                alert(JSON.stringify(error))
            })
        })
    })
    }

    isIconCheckedOrNot = (item,index) => {
    let { isChecked,selectedLists} = this.state;
    isChecked[index] = !isChecked[index];
    this.setState({ isChecked : isChecked});
    if(isChecked[index] == true){
        selectedLists.push(item.list_id)
    }else {            
        selectedLists.pop(item.list_id)
    }

    }



    _renderListItem = ({item,index}) => {
    return(            
        <View >
            <CheckBox
                checked={this.state.isChecked[index]}
                onPress={() => this.isIconCheckedOrNot(item,index)}
            />
            <TextViewNonClickable
                textViewText={item.name}
                textStyle={{color:color.colorBlack,fontWeight:'700'}}
            />
        </View>
    )
}

_onOkPress = () => {
    this.props.closeModal();
}

//render screen
render() {

const {modalVisibility,closeModal} = this.props;

return (

                showsVerticalScrollIndicator={false}
                alwaysBounceVertical
                refreshControl = {
                    <RefreshControl
                        refreshing={this.state.isRefreshing}

I hope this helps you . The problem is in the destructuring of the data for rendering the items of your second flatlist:
code :
renderItem={({ addressItem, index }) => (
                <ListItem
                    title={addressItem}
                    containerStyle={{paddingBottom: -4}}
                    titleProps={{style: styles.dropdownItemStyle}}
                    onPress={() => this.setState({addressInputValue: addressItem}, this.hideAddressesDropdown())}
                />
            )}

I wish this help you Look at "Model mappings" in readme file. There are fields which supported by library and their mappings. Key "pubDate" can be accessed by item.published, key "source" is not supported in spec. You can execute
code :
alert(Object.keys(item));

it fixes the issue if you did react-native link bugsnag-react-native. Then you will need following changes if you are having this issue. I found the solution.
In you Android/settings.gradle put the include bugsnag-react-native under include ':app'
code :
include ':app'
include ':bugsnag-react-native'
project(':bugsnag-react-native').projectDir = new File(rootProject.projectDir, '../node_modules/bugsnag-react-native/android')
libz.tbd and 
libBugsnagReactNative.a
protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
new MainReactPackage(), BugsnagReactNative.getPackage()
