EDIT:

I fixed the issue by removing the question marks from this method:

override fun onMethodCall(call: MethodCall?, result: MethodChannel.Result?)

to this:

override fun onMethodCall(call: MethodCall, result: MethodChannel.Result)

Please provide a solution for this problem by changing your code.
