Upgrader not working after just installing the package

[Gonzalo-Bruna]

I just installed the package, and without doing anything at all, the app already breaks. These are the logs from the debug console:

ERROR:D8: com.android.tools.r8.kotlin.H
ERROR:D8: com.android.tools.r8.kotlin.H

And this is the upgrader version used:

  upgrader:
    dependency: "direct main"
    description:
      name: upgrader
      sha256: "9b907a8c956dbf3f2d0430d16134e27543cba98eab31f19a2240ab1c4d920506"
      url: "https://pub.dev"
    source: hosted
    version: "11.3.0"

By the way I currently have Kotlin 1.7.10 installed, but I’ve tried using other versions without success. I tested the latest version before 2.0 (1.9.25) and also tried Kotlin 2.0.20, but neither worked.
Any solution or ideas of why this could be happening? Thanks in advance

@Gonzalo-Bruna The upgrader package itself does not use any Android native code. It only depends on packages that use native code. You should check all of your dependencies to see which ones require Android Gradle updates.

@larryaasen Thank you for your response. However, I want to clarify a few points:

1. The error occurs immediately after adding the upgrader package to a previously working project. I literally only:

   • Added the package to pubspec.yaml
   • Ran flutter pub get
   • Tried to run the app

2. The app was working perfectly fine before adding upgrader, and the error appears immediately after adding it, without any other changes to the project or its dependencies.

3. The error seems specifically related to Kotlin version conflicts, showing:

   • Issues with annotation-jvm-1.9.1.jar
   • Issues with kotlin-stdlib-2.1.0.jar

Given this sequence of events, it seems the upgrader package might be introducing some indirect dependency that's causing conflicts with Kotlin versions. Could you help me understand:

1. What specific Android Gradle or Kotlin version requirements the upgrader package or its dependencies might have?
2. Are there any known compatibility issues with specific Kotlin versions?

This would help me better understand how to resolve the issue, since the problem appears to be directly related to adding the upgrader package.

This looks more like a usage/support question than an engineering issue. I’m adding the How To? label for now. If there isn’t new actionable engineering detail or a reproducible bug on current code, this may be closed in the future.
