// State Props
const mapStateToProps = state => ({
    userInfo: UserSelectors.getUserInfo(state)
});

// Dispatch Props
const mapDispatchToProps = dispatch => ({
    onGetUserInfo: () => dispatch(UserActions.getUserInfo())
});

// Styles
const contentStyle = {
    flex: 1,
    overflow: 'hidden',
    backgroundColor: Colors.neutralLighterAlt
};

export default withRouter(
    connect(
        mapStateToProps,
