How to use the @react-native-community/netinfo.isConnectionExpensive function in @react-native-community/netinfo

_ensureIsConnectionExpensiveIsUpToDate = () =>
    Platform.OS === 'android' &&
    NetInfo.isConnectionExpensive()
      .then(isConnectionExpensive => this.setState({ isConnectionExpensive }))
      .catch(console.warn)

_checkIfExpensive = () => {
    NetInfo.isConnectionExpensive().then(isConnectionExpensive => {
      this.setState({isConnectionExpensive});
    });
  };

static async isConnectionWifi(): Promise {
    const connectionInfo = await NetInfo.getConnectionInfo()
    const isConnectionExpensive = await NetInfo.isConnectionExpensive()
    Logger.debug(TAG, `isConnectionWifi/Connection type is ${connectionInfo.type}`)
    Logger.debug(TAG, `isConnectionWifi/is connection expensive: ${isConnectionExpensive}`)
    return connectionInfo.type.toString().toLowerCase() === 'wifi' && !isConnectionExpensive
  }
}
