The workaround for this is:

In your render function do something like this:

constructor() {
    this.state = { isLoading: true }
}

componentDidMount() {
    this.setState({isLoading: false})
}

render() {
    return(
        this.state.isLoading ? *showLoadingScreen* : *yourPage()*
    )
}

Initialize isLoading as true in the constructor and false on componentDidMount
