Android Gradle Plugin 7.3 incompatible with device_calendar due to a transitive dependency flutter_native_timezone

[agacemi]

Describe the bug

When upgrading to AGP 7.3.x in order to use kotlin 1.8.x, build failed because of flutter_native_timezone used by device_calendar. flutter_native_timezone seems not be maintained et uses a very old version of kotlin

To Reproduce

• Upgrade to AGP 7.3.1

• Build app

  
  FAILURE: Build failed with an exception.

• What went wrong: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher. The following dependencies do not satisfy the required version: project ':flutter_native_timezone' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

• Try:

  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

• Get more help at https://help.gradle.org

BUILD FAILED in 17s

**Expected behavior**
- Build successful

**Flutter doctor**
Run a `flutter doctor` so we can rule out env issues

Same issue here.

The readme (https://github.com/builttoroam/device_calendar/tree/master#readme) refers to replacement of the apparently stale/deprecated package [flutter_native_timezone] (ref: https://github.com/pinkfish/flutter_native_timezone/issues/53).

There are many issue / PR references to "version 5" (going back ~6 months) which has not been released. The current version at time of writing being 4.3.1.

Discussion of this issue appears to be here https://github.com/builttoroam/device_calendar/issues/474

[agacemi]

I think I found that it's not going well. The package 4.3.1 in pub dev (https://pub.dev/packages/device_calendar) was pushed from master branch, not from 4.3.1 tag.

For this reason, the two fellowing configuration don't give the same thing:

  device_calendar:
    git:
      url: https://github.com/builttoroam/device_calendar.git
      ref: 4.3.1

  device_calendar: ^4.3..1

Please push the right version of plugin on pub dev

[VeryGiack]

Any news on this?

[agacemi]

@VeryGiack a workaround is to use in your pubspec.yaml

  device_calendar:
    git:
      url: https://github.com/builttoroam/device_calendar.git
      ref: 4.3.1

instead of

  device_calendar: ^4.3.1

cf . reason in my last comment https://github.com/builttoroam/device_calendar/issues/483#issuecomment-1527022138

[VeryGiack]

Hi @agacemi using:

device_calendar:
    git:
      url: https://github.com/builttoroam/device_calendar.git
      ref: 4.3.1

give me this error:

[agacemi]

Which version of kotlin you use ? This must be at least kotlin 1.6

[VeryGiack]

Ohh thanks i was using 1.5.30, i'll try with 1.6

[VeryGiack]

I've updated to kotlin 1.8.21 (current latest) and now it works, thx @agacemi

Hi @thomassth or others... Any update on this? It would be good with a release (4.3.2 ?) that uses the flutter_timezone plugin instead of the deprecated flutter_native_timezone plugin.

The current version (4.3.1) is causing a lot of problems.... And we can't use the GitHub branch linked above, since we are using this device_calendar in another published Flutter package to be released at pub.dev. And you can't publish plugins that rely on non-published packages....

[thomassth]

If someone makes a PR I'll approve it

Otherwise I don't have an estimate, and neither do any of the other maintainers it seems

tbf most of us only became "maintainers" to push some PRs we had at the time, and if you wanna help maintain this package, check out the discussion topic and leave a note there

[agacemi]

@bardram @thomassth I would just to note that there is a workound by using gît tag 4.31 instead of using pub dev version 4.31.

Cf. my comment above, i explain why. Regards

It works. but I think we need a patch fix version like 4.3.2 in pub.dev.

[thomassth]

I need someone other than me to create a PR so I can approve and merge. Can do both on my own.

[bardram]

Seems like this has been fixed and merged now - now someone with publish access to pub.dev should publish a new version.

Thanks.

[azmasamy]

Would any maintainer please publish the new version?

[thomassth]

It has to be @nickrandolph While we may have a few (busy) maintainers, only nick can get the (updated) API key needed for publishing.

[nickrandolph]

@thomassth I tried emailing you re ownership of the repo. Get back to me, or DM on twitter, so we can unblock this

[azmasamy]

Could any of the maintainers fork the repo and create another package that is properly updated?

Also there is an update in the IOS calendar API for IOS17. I can't ask for calendar permission using the package but I don't know if it effects any other feature.

[thomassth]

For now, you can ask for iOS 17 specific permissions with flutter plugins that handles device permissions.

I've DM'd nick, so we might have some news after the weekend.

[bardram]

It seems like this issue has been fixed with release 4.3.2 - am I right?

If so, this issue can be closed.

[agacemi]

Thank you I conform it fix the issue and thus can be closed.
