Actual behaviour

Question: How to replace the default play/pause icon in notification
Phenomenon:
Modify the button control in the notification in the controls parameter of PlaybackState, clear the list, and there will be a default play/pause icon switching function on the UI;

Add MediaControl.play with the same name but replace the iconMediaControl.play.copyWith(androidIcon: "drawable/baseline_forward_30_24") that displays the default icon;

Adding a picture with the same name as the default icon to the drawable cannot replace the default play and pause icons. But stop can be replaced.
The image is not modified: MediaControl.pause.copyWith(androidIcon: "drawable/audio_service_stop"),
Image modification: MediaControl.stop,
Image modification: MediaControl.rewind.copyWith(androidIcon: "drawable/audio_service_stop"),

Add a custom type of controls, and the icon can take effect normally.

In the example you provided, you can reproduce this problem by directly modifying the content in controls. No other modifications are required.

Minimal reproduction project

Official example: example_android13.dart

Reproduction steps

Modify the control parameter content in the _transformEvent method and add the corresponding test image to the drawable.

Because slot 1 of android controls cannot be customized, the function of slot 1 cannot be modified?

If you want to ask a question about how set the icons on Android, please follow the instructions on the New Issue page which direct you to StackOverflow (the question asking/answering site). If you find the answer, hopefully it works for you. If you discover that you need me to expose more of the Android API in this plugin, you can come back here and submit a feature request detailing exactly what parts of the API are missing.
