Package Duplication Conflict when using facebook_app_events with flutter_facebook_login plugins in the same project

[MohamadSobhy]

Hi,

I added facebook login feature using the flutter_facebook_login package and it works as excpected but after adding the facebook_app_events to the project to send events to facebook analytics the app crashes when trying to login using facebook for the first time and throws the below exception. after some searching i figured out that this error may happen because of plugins duplication or adding plugin multiple time with different versions. i faced a similar issue on IOS but i solved it by changing the version of the FBSDKCoreKit to 7.1.0 manualy in ios/.symlinks/plugins/flutter_facebook_login/ios/flutter_facebook_login.podspec to be the same as the version which facebook_app_events works on but i can't solve the issue with Android. How can i solve this conflict and prevent package duplication on android? Any Help??

I refactored my project to use facebook_analytics plugin instead of facebook_app_events and everything works as expected.

Try doing the same until resolving this issue by the author.

[jgrandchavin]

Same issue for me...
And facebook_analytics don't have the new logPurchase method, I will create an issue on flutter_facebook_auth repo

[tangzigang]

the same problem fo me ...

[crtl]

I am having the same issue.

Please use the issue template for "bug report" to provide full context.

[DennisAlund]

@MohamadSobhy is this still an issue for you, can you provide full context according to the bug report issue template so that we can try and troubleshoot it together

Migration on flutter_login_facebook resolved problem for me

[DennisAlund]

@NaikSoftware could you give me some more information on what you did when you did the "migration" and how that resolved your issue?

[DennisAlund]

I noticed that there is another "Facebook Login" plugin that seems to be more actively maintained and using a more recent version of the Facebook SDK: https://pub.dev/packages/flutter_facebook_auth

Please don't take this as an encouragement to use that plugin instead. But I'm just putting it into the discussion to see if there is anyone who have better success with compatibility using that one.

I'm using the package mentioned above, cant run pod install:

[!] CocoaPods could not find compatible versions for pod "FBSDKCoreKit":
  In Podfile:
    facebook_app_events (from `.symlinks/plugins/facebook_app_events/ios`) was resolved to 0.0.1, which depends on
      FBSDKCoreKit (~> 8.1.0)

I'm also having this issue. There is a bug on iOS when using FBSDKCoreKit 8.1.0, so it needed to be updated to 8.2.0 in flutter_facebook_auth I guess.

@DennisAlund Do you think we could get a bump to 8.2.0?

[lukasloh]

I'm having the same issue with FBSDKCoreKit 8.1.0 on iOS. I've created a PR for the bump to 8.2.0 (#65).

[DennisAlund]

PR #65 has been merged to develop and released in v0.8.2

[haneensaadeh1994]

the issue still exist in version 0.8.2 !!

[tim-teacher]

@DennisAlund Why it is closed?, issues is still here.
