1 What it is the problem?

There is a file descriptor leak problem in Flutter. And you Konw that every android phone has a limit of maximum file descriptor. when your application fd(file descriptor) is bigger than the maximum fd,your application will be crash.

2 How to repeat this problem?

this is demo source code
you can run this project and dont need to modify any code but just print the below log
Log.i("TAG", "onCreate: getFdCount " + ProcessUtil.getFdCount());
when you print this log for 5 minutes, you can find the number will be bigeer and bigger.

please use non-Qualcomm cpu mobile phone to test this problem , Qualcomm cpu phone cant repeate this question, May be Flutter cant support other cpu ？
