'readRssi' Method Not Defined for 'ReactiveBlePlatform'

[DeToxer]

Describe the bug After upgrading the flutter_reactive_ble library from version 5.2.0 to 5.3.0, the app fails to compile on both Android and iOS platforms. The compiler error indicates that the method readRssi isn't defined for the class ReactiveBlePlatform. This issue has been tested and confirmed on two devices: an iPhone simulator (iOS version 17.0, iPhone 15 Pro Max) and an Android emulator (Pixel 7 Pro API 33). The problem persists despite attempts to clean the build environment using flutter cleanand flutter pub cache clean --force. Notably, this issue does not arise in a newly created Flutter project.

Smartphone / tablet Device: iPhone 15 Pro Max/Pixel 7 Pro OS: iOS 17.0/Android 12 (SDK 33) Package version: flutter_reactive_ble 5.3.0

Additional context The issue appears to be specifically associated with version 5.3.0 of the flutter_reactive_ble library. Reverting to version 5.2.0 or initiating a new Flutter project does not result in this compile-time error, suggesting that the problem is isolated to this particular version update.

I ran into the same problem. My solution was to force this in pubspec.yaml without the "^"

flutter_reactive_ble: 5.2.0

Up tp now, I had it as "^5.2.0" with the "^" (which allowed never versions, such as the ill-fated 5.3.0).

Now, 5.3.0 is not allowed and things continue to work perfectly with 5.2.0.

Then, I deleted this directory:

~/.pub-cache/hosted/pub.dev/flutter_reactive_ble-5.3.0/

[farr64]

I'm sure the good folks in charge of this wonderful package will come up with 5.3.1 ASAP.

Thanks!

I have the same issue.

[farr64]

I'm afraid everyone who goes from 5.2.0 to 5.3.0 will have the same issue. See my solution above: Stay on 5.2.0 and disallow 5.3.0.

Of course, as soon as 5.3.1 (or whatever) is released, change your pubspec.yaml to whatever will be applicable then. For instance:

flutter_reactive_ble: ^5.3.1

[DeToxer]

I see that the pubspec.yaml inside flutter_reactive_ble and reactive_ble_mobile still targets reactive_ble_platform_interface: ^5.2.0and reactive_ble_mobile: ^5.2.0 instead of 5.3.0. That might be the issue.

Edit: I also see that the lock files are checked in where the dependencies (reactive_ble_mobile and reactive_ble_platform_interface) are pinned to 5.2.0

my bad will fix it and make realese soon
