Android build fails - Deprecated api

[Pingolus]

Hi,

Flutter pub get outputs some warnings about device_calendar :

The plugin `device_calendar` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future
release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

And app build fails for Android :

e: [...]snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/device_calendar-3.9.0/android/src/main/kotlin/com/builttoroam/devicecalendar/CalendarDelegate.kt: (674, 36): Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type Activity?
e: [...]snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/device_calendar-3.9.0/android/src/main/kotlin/com/builttoroam/devicecalendar/CalendarDelegate.kt: (870, 65): Using 'max(): T?' is an error. Use maxOrNull instead.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':device_calendar:compileReleaseKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
   > Compilation error. See log for more details

This is my flutter doctor summary :

Is this package still maintained, is there any solution ?

Thanks

I don't think we've been maintaining 3.x versions
Try upgrading the package?
