Running into the same problem, I mainly noticed the inbuild Games app from OxygenOS triggers this null pointer exception when a Game is started. Even when removing all games the null pointer happens sooner or later, so it's not exclusively a Games issue .

Seems no one is responding. I had this issue before and had to open the package in \AppData\Local\Pub\Cache\hosted\pub.dartlang.org\notifications-2.0.1\android\src\main\java\dk\cachet\notifications then update the NotificationListener.java file. I changed the line intent.putExtra(NOTIFICATION_MESSAGE, text.toString()); to intent.putExtra(NOTIFICATION_MESSAGE, text==null?"":text.toString()); You might have to change the line before this too in the same way if you still get errors.

For me this error showed up everytime an email notification came through for gmail
