Material-ui: How do you make a horizontal List

So far I have:

const flexContainer = {
  display: 'flex',
  flexDirection: 'row',
  padding: 0,
};

return (
  <List style={flexContainer}>
    <ListItem
      primaryText="foo1"
      secondaryText="bar1"/>
    <ListItem
      primaryText="foo2"
      secondaryText="bar2"/>
  </List>
);

This works. Looking for a potential better answer / opinions. Should this be built in?

After playing around

.list-horizontal-display > div {
    display: inline-block;
}

<List className="list-horizontal-display" >
   <ListItem leftAvatar={<Avatar icon={this.props.icon}/>}></ListItem>
   <ListItem leftAvatar={<Avatar icon={this.props.icon}/>}><ListItem>
</List
