How do i show the current CodePush Version label in my React Native Android app?

If there are no updates available, getUpdateMetadata() returns null...

Workaround:

import codePush from "react-native-code-push";

async function getAppVersion() {
    const [{ appVersion }, update] = await Promise.all([
    codePush.getConfiguration(),
    codePush.getUpdateMetadata()
    ]);

    if (!update) {
        return `v${appVersion}`;
    }

    const label = update.label.substring(1);
    return `v${appVersion} rev.${label}`;
};

export { getAppVersion };

Example output: v1.4.4" OR v1.4.4 rev.5" depending on state.

componentDidMount(){
    codePush.getUpdateMetadata().then((metadata) =>{
      this.setState({label: metadata.label, version: metadata.appVersion, description: metadata.description});
    });
}

render() {
    return(
        <Text>{this.state.version}.{this.state.label}</Text>
    );
}

Note: The .label property is the internal build number used by CodePush (e.g. v24)
