I'm sorry for not supporting this. I don't use material-ui-pickers anymore or even react as a whole (in favor of svelte). This was simply intended as a quick hack that others could modify for their use case. Hence why it's a gist not an npm package. It looks like later version of material-ui-pickers changed enough as to break this. I don't have plans to to update this but if anyone else wants to take a crack at it feel free.

how to use the labelFunc property? i'm trying to change the label in which if the start date and end date is the same, the label should only be date.
