1.2.14 / Flutter 3.0.0 Operand of null-aware operation

[1N50MN14]

Flutter still complains about that with 1.2.14:

../../../../Applications/flutter/.pub-cache/hosted/pub.dartlang.org/ably_flutter-1.2.14/lib/src/platform/src/streams_channel.dart:54:23: Warning: Operand of null-aware operation '!' has type 'ServicesBinding' which excludes null.
 - 'ServicesBinding' is from 'package:flutter/src/services/binding.dart' ('../../../../Applications/flutter/packages/flutter/lib/src/services/binding.dart').
      ServicesBinding.instance!.defaultBinaryMessenger

../../../../Applications/flutter/.pub-cache/hosted/pub.dartlang.org/ably_flutter-1.2.14/lib/src/platform/src/streams_channel.dart:87:23: Warning: Operand of null-aware operation '!' has type 'ServicesBinding' which excludes null.
 - 'ServicesBinding' is from 'package:flutter/src/services/binding.dart' ('../../../../Applications/flutter/packages/flutter/lib/src/services/binding.dart').

@1N50MN14 thank you for the report. I'm afraid there's nothing we can do with this, if you take a look at these methods, there is a comment and ignored lint warning for that:

// We need to keep this null-asserted for backwards compatibility with
// Flutter versions before 3.0.0
// ignore: unnecessary_non_null_assertion

The ServicesBinding.instance became non-nullable with Flutter 3.0.0, but we still need to keep the null safety here, because minimum required Flutter version we support is 2.5.0, where the ServicesBinding.instance can still be nullable. Updating these components would require us to drop support for Flutter versions before 3.0.0, which isn't planned for now

what do you mean you can do nothing? it's just a null-safety thing. do you mean both minimum and maximum is 2.5.0? haha
