read-only
A callback which filters the stack trace. Receives an iterable of
strings representing the frames encoded in the way that
StackTrace.toString() provides. Should return an iterable of lines to
output for the stack.
If this is not provided, then FlutterError.dumpErrorToConsole will use FlutterError.defaultStackFilter instead.
If the FlutterError.defaultStackFilter behavior is desired, then the
callback should manually call that function. That function expects the
incoming list to be in the StackTrace.toString() format. The output of
that function, however, does not always follow this format.
This won't be called if stack is null.
