Describe the error

I was following the setup for iOs and when reaching the "You MUST amend your AppDelegate.swift and Info.plist file to register your task ID." I receive those errors in Xcode.

I have cloned this repo and the same errors show on the example (on the flutter side there are 4 errors like: error: The method 'registerProcessingTask' isn't defined for the type 'Workmanager'. (undefined_method at [workmanager_example] lib/main.dart:266)

Output of flutter doctor -v

You may try to change the branch of the package in pubspec.yaml file:

  workmanager:
    git:
      url: https://github.com/absar/flutter_workmanager.git
      ref: ios-bg-tasks-enh-final

It may help you to solve your issue at this moment.

The above solution seems to work, I'm now able to build the app and triggering the background task from the debugger works. Could we get a comment whether this is the "correct" solution for making this plugin work on iOS at the moment?

I got the same error !!

Don't you think that it's weird? The official git link is https://github.com/fluttercommunity/flutter_workmanager but you are pulling code from https://github.com/absar/flutter_workmanager.git who knows what he could code there.

joonne commented 1 month ago

I could have elaborated a bit, those changes from https://github.com/absar/flutter_workmanager.git are actually in main already and waiting to be released: https://github.com/fluttercommunity/flutter_workmanager/commit/b783000c18f6e066f3d81d5ecc352f3ce61860f6 👍

(or that is how I understood the situation)

I spend too much time figuring out why the described setup is not working with my project until I realized that the link to the iOS Setup brings you to the GitHub Repo, has a different version than the one that is published on pub.dev 🥲 So for others that are struggling use the right version in your pubspec.yml and read the Readme's from that commit b783000.

Pubspec

  workmanager:
    git:
      url: https://github.com/fluttercommunity/flutter_workmanager.git
      ref: b783000

I am now using this version instead of the 0.5.2 version and at first it worked fine, but now I get an error on Android:

  • What went wrong: Execution failed for task ':app:checkDebugDuplicateClasses'.

    A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable Duplicate class androidx.work.OneTimeWorkRequestKt found in modules work-runtime-2.8.1-runtime (androidx.work:work-runtime:2.8.1) and work-runtime-ktx-2.7.0-runtime (androidx.work:work-runtime-ktx:2.7.0) Duplicate class androidx.work.PeriodicWorkRequestKt found in modules work-runtime-2.8.1-runtime (androidx.work:work-runtime:2.8.1) and work-runtime-ktx-2.7.0-runtime (androidx.work:work-runtime-ktx:2.7.0)

I really need the periodic tasks to work on iOS, so I hope someone can help me with this since they don't work in the 0.5.2 version.

Hi, try adding this line inside the dependencies array found in /android/app/build.gradle:

implementation("androidx.work:work-runtime-ktx:2.8.1")

Anything to help this fixed version being released on pub.dev?
