How do you conditionally show fields in “Show” component in react-admin?

Question

Some fields I want to only show if they have a value. I would expect to do this like so:

  
    { props.reco

We need to update our documentation about this. In the mean time, you can find informations about how to achieve that in the upgrade guide: https://github.com/marmelab/react-admin/blob/master/UPGRADE.md#aor-dependent-input-was-removed

Here's an example:

import { ShowController, ShowView, SimpleShowLayout, TextField } from 'react-admin';

const UserShow = props => (
    <ShowController {...props}>
        {controllerProps => 
            <ShowView {...props} {...controllerProps}>
                <SimpleShowLayout>
                    <TextField source="username" />
                    {controllerProps.record && controllerProps.record.hasEmail && 
                        <TextField source="email" />
                    }
                </SimpleShowLayout>
            </ShowView>
        }
    </ShowController>
);
