[jni_flutter] 1.0.4 requires package:jni ^1.1.0 but pubspec still allows ^1.0.0 #3722

Summary

jni_flutter 1.0.4 (published 2026-10-01) contains generated bindings that assert package:jni ^1.1.0 at compile time via JniVersionCheck(1, 1), but its pubspec.yaml still declares jni: ^1.0.0. Pub therefore happily resolves jni_flutter 1.0.4 alongside jni 1.0.x, and the app then fails to compile instead of failing at version resolution.

Steps to reproduce

1. In a Flutter app that (transitively) depends on jni_flutter, constrain jni to 1.0.x, e.g.

   dependency_overrides:
     jni: 1.0.0   # workaround for #3497 (AGP 9)

2. Run flutter pub get with no lockfile -> resolves jni_flutter 1.0.4 + jni 1.0.0.
3. flutter build macos (also reproduced on other targets).

Expected result

jni_flutter 1.0.4's pubspec should declare jni: ^1.1.0 so that pub either picks a compatible jni or falls back to jni_flutter 1.0.3, rather than producing a broken build.

Suggested fix

• Bump the jni lower bound in pkgs/jni_flutter/pubspec.yaml to ^1.1.0 and publish 1.0.5.
• Consider retracting 1.0.4 on pub.dev, since any project resolving it with jni < 1.1.0 is broken.
• Possibly add a CI check that the JniVersionCheck emitted by jnigen matches the jni constraint in the package's pubspec.

Workaround

dependency_overrides:
  jni_flutter: 1.0.3

Environment

• Flutter 3.47.5 (stable)
• jni_flutter 1.0.4, jni 1.0.0
• Building on macOS (Azure Pipelines hosted agent)
