I wanted to use a DatePickerInput that requires a start date and the end date should be optional and I found the prop allowSingleDateInRange which sounded perfect for that case unfortunately the input triggers an onChange with [null, null] when only one value is selected. I am not sure if this a bug or a misunderstanding on my side ?
