@rachidev84 Can you provide your code please?

rachidev84 commented 2 years ago

This is my code:

TimerCountdown( format: CountDownTimerFormat.daysHoursMinutesSeconds, endTime: DateTime.now().add(durationTime), onEnd: () { //print("Timer finished".tr); }, timeTextStyle: ThemeColor.grayDarkTextH1, descriptionTextStyle: ThemeColor.grayTwoLightH2), ),TimerCountdown( format: CountDownTimerFormat.daysHoursMinutesSeconds, endTime: DateTime.now().add(durationTime), onEnd: () { //print("Timer finished".tr); }, timeTextStyle: ThemeColor.grayDarkTextH1, descriptionTextStyle: ThemeColor.grayTwoLightH2), ),

//durationTime is different time between two date when I navigate to screen that display date: 00:00:00:00 and the error occur when I go back to previous screen.

tobiasbentin commented 2 years ago

Hello @rachidev84 , I tried to get this error with navigating back but could not reproduce your issue. Could you provide a full working example which throws this error please?

rachidev84 commented 2 years ago

There's one issue appear before showing the whole message, is : LateInitializationError: Field 'timer' has not been initialized, got error I fix the issue by following these steps below:

1- Timer? timer; instead of late Timer timer; 2- Check if timer is null before cancel it @override void dispose() { if (timer != null) { timer!.cancel(); } super.dispose(); }

tobiasbentin commented 2 years ago

@rachidev84 thanks for your help. I changed the code in the package so it will be included in the next update :)
