downgrade analysis failed failed with 1 error:

• NON_ABSTRACT_CLASS_INHERITS_ABSTRACT_MEMBER - lib/src/raw_receive_port_multiplexer.dart:31:7 - Missing concrete implementations of 'getter RawReceivePort.keepIsolateAlive' and 'setter RawReceivePort.keepIsolateAlive'.

Run dart pub downgrade and then dart analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
