 initialTime: TimeOfDay(
                        hour: _available.first,
                        minute: _availableMinutes.first)

CodePudding user response：

I think error is that line:

_availableMinutes.indexOf(time.minute)

Does selectableTimePredicate allow select value "25"? If yes, then error make sense.
