android – TableCalendar Not Updating State Appropriately

I’ve an inventory, so one thing like

var x = [DateTime(xxxx), DateTime(xxxx)];

And I wish to present customers the times they labored out, so I would like the times in that listing to seem inexperienced, let’s imagine. Nonetheless, once I navigate to a brand new month and generally simply navigate in any respect, the inexperienced circle disappears. I do know my operate is used appropriately, as a result of the font measurement differs from the default textual content, however it would not present the circle. I included photos of the problem and the code for the calendar is linked under. Thanks!

                           Container(
                              width: measurement.width * .9,

                                firstDay: DateTime.utc(1900, 10, 16),
                                lastDay: DateTime.utc(2200, 3, 14),

You possibly can see within the picture the 25, 26, 27, 28, and 29 for feb is chosen (with a gray circle), however once I go to march, only one and a pair of are chosen, not 25, 26, 27, 28, and 29.
