Dart/Flutter How to compare two TimeOfDay times?

Question

TimeOfDay documentation has no comparison operator and primitive comparison does not work. My only solution that I can thinking of right now is to convert TimeOfDay to DateTime and use DateTime's difference method.

Does anyone have a better solution?

Answer 1

Convert it to a double then compare.

double toDouble(TimeOfDay myTime) => myTime.hour + myTime.minute/60.0

Answer 2

Thanks from @Lucas idea, you can calculate hour and minute by

TimeOfDay yourTime ; 
TimOfDay nowTime = TimeOfDay.now()

double _doubleYourTime = yourTime.hour.toDouble() +
            (yourTime.minute.toDouble() / 60);
double _doubleNowTime = nowTime.hour.toDouble() +
            (nowTime.minute.toDouble() / 60);

double _timeDiff = _doubleYourTime - _doubleNowTime;

double _hr = _timeDiff.truncate();
double _minute = (_timeDiff - _timeDiff.truncate()) * 60;

print('Here your Happy $_hr Hour and also $_minute min');
