Selecting the last date in DateRangePicker.showDatePicker throws assert error in MonthPicker

[olaide-ekolere]

Hi,
This is my code
var picked = await DateRagePicker.showDatePicker(
context: context,
initialFirstDate: DateTime.fromMillisecondsSinceEpoch(
_flightSearch.itineraries[0].departureDate),
initialLastDate: (DateTime.fromMillisecondsSinceEpoch(
_flightSearch.itineraries[1].departureDate)),
firstDate: DateTime.now().add(Duration(days: -1)) ,
lastDate: tenYears,
);
when the picker is opened and the user selects the last year and the last date, MonthPickers " assert(!selectedFirstDate.isBefore(firstDate) &&
(selectedLastDate == null || !selectedLastDate.isAfter(lastDate)))" is fired.

I have the same problem.

I observed this problem whenever I pick a different year (especially the last year) then tried to select a date. It seems the selectedLastDate becomes greater than the widget.lastDate

The hack I came up with was to

1. Make a copy of the date_range_picker.dart file
2. do a conditional if check and re-assign the selectLastDate if it's greater than the widget last date.
