Flutter workmanager: registration a new task with the same name

Question

In the application I need to change a workmanager duration time for the same task. I'm not sure is it required to cancel this task before? For instance

Workmanager.registerPeriodicTask(
    "1",
    simplePeriodicTask,
    initialDelay: Duration(seconds: 10),
    frequency: Duration(minutes: minutes), //20 minutes
);

and after some time

Workmanager.registerPeriodicTask(
    "1",
    simplePeriodicTask,
    initialDelay: Duration(seconds: 10),
    frequency: Duration(minutes: minutes), //40 minutes
);

This is the same task. Do I need to cancel it before register a new one with the same name?

Answer 1

It's clearly mentioned in the documentation

Existing Work Policy

Indicates the desired behaviour when the same task is scheduled more than once. The default is KEEP

Workmanager.registerOneOffTask("1", "simpleTask", existingWorkPolicy: ExistingWorkPolicy.append);
