flutter - 如何取消特定计时器？

Question

如果我为3个不同的功能运行3个不同的计时器，我该如何取消特定的计时器。

例

const oneSec = const Duration(seconds: 60);
        new Timer.periodic(
            oneSec,
            (Timer t) async =>
                await appLoggerRepository.putAppLogOnServer(jobName));

const oneSec = const Duration(seconds: 60);
        new Timer.periodic(
            oneSec,
            (Timer t) async =>
                await appLoggerRepository.uploadOrder(jobName));

const oneSec = const Duration(seconds: 60);
        new Timer.periodic(
            oneSec,
            (Timer t) async =>
                await appLoggerRepository.checkdevice(jobName));

您必须创建一个计时器变量

Timer logTimer = Timer.periodic( //no need for the new keyword
            oneSec,
            (Timer t) async =>
                await appLoggerRepository.putAppLogOnServer(jobName));

//to cancel call cancel()
logTimer.cancel();
