You are calling withTheme(Component) with an undefined component. You may have forgotten to import it.

If I try and use with react-admin

import { DateTimeInput } from 'react-admin-date-inputs';

with

<DateTimeInput label="Start" options={{ format: 'DD/MM/YYYY, HH:mm:ss', ampm: false, clearable: true }} />

Error: You are calling withTheme(Component) with an undefined component.

Have you managed to solve this? I have the same problem after upgrading to react-admin 3.0

Hello! I've got the same issue. Did anyone find a solution? I guess it's about material-ui versions incompatibility
