Error building with Flutter 3.29.0

After upgrading Flutter to 3.29.0 I receive an error while building with flutter build apk on Windows.

C:\Users\giaco\AppData\Local\Pub\Cache\hosted\pub.dev\sound_generator-0.0.13\android\src\main\java\io\github\mertguner\sound_generator\SoundGeneratorPlugin.java:11: error: cannot find symbol

Commenting those two sections in SoundGeneratorPlugin.java it builds and works correctly.

Could this be related to the deprecation of those API in the latest SDK?

Thank you
