What is your problem?

}

Unable to disconnect cached connection

Question 2:
If connecting a cache device:

 final cache = await FlutterBluePlus.systemDevices
 for (var element in cache) {
element .connect()......
//....
await characteristic.setNotifyValue(true)
characteristic.onValueReceived.listen(e){
//There will be duplicate callback data here
//The device's callback will send the same data twice each time
}
}

Logs

for question 1. you are correct. Those devices are not connected to your app. you cannot disconnect them. You can try connecting then disconnecting, im not sure what will happen tbh.

for question 2, see README. duplicate data is common problem.
