Warning related to `?` operator on Linux/Dev channel. #228

After updating my flutter installation (Channel beta, 2.12.0-4.2.pre), I get the following warnings:

Launching lib/main.dart on Linux in debug mode...
ERROR: ../../../Apps/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_redux-0.9.0/lib/flutter_redux.dart:474:22: Warning: Operand of null-aware operation '?.' has type 'WidgetsBinding' which excludes null.

Apparently, WidgetsBinding.instance will return a not-null value in the future.

Thanks! Publish 0.10.0-beta.1 to fix this up.

Oops, didn't mean to close. I'll close this one out once the WidgetsBinding.instance change is on Flutter stable and we can publish 0.10.0 properly.
