PlatformException on MacOS through amplify_secure_storage and amplify_auth

[pixnbit]

Description

Hi, we've been using Amplify Auth in production, and recently upgraded to the latest. No issues with Android, iOS, and Web, but on the MacOS the app would not launch with the following exception:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

I have the following amplify versions:

  amplify_auth_cognito: 2.4.0
  amplify_authenticator: 2.1.2
  amplify_flutter: 2.4.0

I searched around didn't find anywhere people mentioning it. I read through the migration guide and did not find anything related to this

Is it a bug in the framework? Thanks for looking into it

Hello @pixnbit - I will see if we can reproduce this. I have a few questions to help with the reproduction:

• What version of MacOS have you observed this on?
• What version of Amplify Flutter are you upgrading from?
• Are you also upgrading your version of Flutter at the same time? If so, from what version?
• Do you observe that this issue goes away if you downgrade Amplify packages to the previous version you were using?

[pixnbit]

Thanks Jordan!

MacOS 14.6.1 (23G93)

The before versions:

  amplify_auth_cognito: 1.7.2
  amplify_authenticator: 1.5.5
  amplify_flutter: 1.7.0
  aws_common: 0.6.5

after:

  amplify_auth_cognito: 2.4.0
  amplify_authenticator: 2.1.2
  amplify_flutter: 2.4.0
  aws_common: 0.7.2

Yes it was around the same time with upgrading the Flutter version from 3.22.3 to 3.24.1. But I tried the older versions of amplify auth on 3.24.1, there were no issues.

I revert to the previous versions and it worked fine, MacOS app launched.

I just added PR, I tested on macOS it works, I don't know if it's intended but macOS pluginClass was missing on amplify_secure_storage's pubspec, I think we need urgent bug fix release for this.

[Jordan-Nelson]

@MarlonJD Thanks for the PR. I was able to reproduce this. We will review and look to get a release out as soon as possible.

[Jordan-Nelson]

This has been released in amplify_secure_storage v0.5.6. You can run flutter pub upgrade to get the latest version. Thank you for your contribution @MarlonJD!
