[balvinderz]

do you have both package_info and package_info_plus as dependencies in pubspec.yaml?

[jasonlaw]

Nope, I clean up explicitly the package_info before running the test, somehow it will generated out again.

[marcschw]

The problem is that package_info and package_info_plus share the same identifier and that many packages have package_info as a dependency.
I just had the same error because I installed in_app_review which seems to be depending on package_info but after removing in_app_review everything works fine.

I'll have to use another package_info class though since I do need in_app_review.

[miquelbeltran]

Thanks for reporting this. Indeed this is a major breaking issue that happens with all packages.

It can be reproduced with these easy steps:

1. Select one package (e.g. android_intent_plus).
2. Open the example project.
3. Add the non-plus version of the package to the pubspec.yaml (e.g. android_intent)
4. Run the example.
5. See error in log:

D8: Program type already present: io.flutter.plugins.androidintent.BuildConfig
java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: 
Program type already present: io.flutter.plugins.androidintent.BuildConfig

The way to fix this will be to move all Android plugins to a different java package structure, e.g. io.flutter.plugins.androidintentplus.

[miquelbeltran]

Hi @jasonlaw, thanks for reporting the issue originally and sorry that it took us a while to fix it.

We have released version 0.6.0 of the package that fixes this issue by doing two things:

1. Move the Java files to another Java package to avoid the "already present" issue.
2. We renamed the method channel name, to also avoid collisions with an existing package_info.

Now both packages can be used at the same time without conflicts. I have tested this solution on Android and iOS.
