[Luktm]

Issue

Where operator turn out error when key in "!=" and "array_contains". I do not know which part i did wrong.

import React, {Component} from 'react';
import {
    ScrollView,
    TouchableOpacity,
    Text,
    View,
    TouchableWithoutFeedback
} from 'react-native';
import firebase from 'react-native-firebase';

class ChatTicketList extends Component {

    state = {
        tickets: {}
    };

    componentWillMount() {
        firebase.firestore().collection('tickets').where('fruit', 'array_contains', 'apple')
            .onSnapshot(collection => {
                const tickets = {};

                collection.forEach(doc => {
                    tickets[doc.id] = doc.data();
                });
                this.setState({tickets})
            });
    }
}

array_contains isn't available yet. It'll be available in the next v5 rc release.

@Ehesp when is the expected release date for v5 rc? Is there any way to start testing array_contains now?

[Ehesp]

Within the next couple of weeks. PRs for the feature are very welcome.

Maybe it's only available for web version? you can try to test it out, maybe?

[Ehesp]

We need to do the native integration. It will probably be there on the Web,
although we've not tested it'll work with the react native environment.
Just be aware you may lose out on other modules you're using.

@Luktm @felixchan v5.0.0-rc4 has just been published with firestore array-contains filtering support.

Note that the correct usage is with a dash (array-contains), not an underscore (array_contains).
