How to cancel background task in iOS

[whoch-g2e]

Hi. Thanks for supporting a good package😇

I'm using this package to develop log sync in the background.
My functions are optional, so I need to cancel on iOS.

I'm cancel using cancelByUniqueName on Android, what should I do with iOS?

[Ascenio]

I think both cancelByTag and cancelByUniqueName should work, whatever might be the OS.

@Ascenio I think the same thing. But In my knowledge, It's only for Android😢

[Ascenio]

Both of them?

[whoch-g2e]

Yes. registerPeriodicTask, Tagging and Cancellation(cancelByTag, ...) all belong to Customisation (Android only!)

In addition, in the example of packages, the Cancel button is enable Android only.

PlatformEnabledButton(
    platform: _Platform.android,
    child: Text("Cancel All"),
    onPressed: () async {
        await Workmanager.cancelAll();
        print('Cancel all tasks completed');
    },
),

[Ascenio]

Weird. I thought the 'Android only' thing were about periodic tasks only. If so, it makes the plugin not very helpful for iOS.

I don't think its possible with this lib, background_fetch should work out of the box

Please try using cancellation with the latest version 0.5.0-dev.8 which utilizes the background task APIs.
