How To make interactive notification in Flutter

Because of the way android notifications work, you can only really customize them with android code (for now at least). So unfortunately, you're going to have to write some native code here.

The actual notification part is the exact same as directly with android in this case, so you can simply look that up. Here's a start though.

The other part to this is that you need to communicate between your flutter code and the native code which handles the notification. To do so, you need to use Platform Channels. Platform channels are things you register so that you can send data back and forth between java/kotlin/objc/swift and dart, in the form of events or 'method calls'. The docs do a better job than me of explaining how to use them.

This new package has something like it.. I have not tried it though and it's still pretty new https://pub.dev/packages/audio_manager

This flutter dependency seems to do the work for me:-
