fix: bump Android compileSdk to 36 across all plugins for AGP 9 compatibility

[pierrejean75]

Problem

Under Android Gradle Plugin 9, the strict checkDebugAarMetadata task fails the build when a plugin module compiles against an Android SDK older than what its (transitive) dependencies require — e.g. the Google native ML Kit AARs now require compileSdk 36. This blocks any app building on AGP 9 (Flutter's upcoming default).

Fix

Bump compileSdk from 35 to 36 across all plugin Android modules in the monorepo (22 packages, including google_mlkit_commons). Build-configuration only — no source or public API changes.

Updated per review (@fbernaly: bump the rest of the plugins; @Copilot: google_mlkit_commons was still at 35 in-repo — now bumped too).

Environment

• Flutter 3.44 (stable), AGP 9.x, Gradle 9.x, JDK 21

@pierrejean75 : could you bump the rest of the plugins as well as part of this PR? and make sure to test with the example app.

Pull request overview

Updates the Android build configuration for google_mlkit_face_detection to avoid AGP 9 checkDebugAarMetadata failures by compiling against a newer Android SDK level.

Changes:

• Bump compileSdk for google_mlkit_face_detection Android module from 35 to 36.

@pierrejean75 ^^ address this as well

Thanks for the quick review! Updated:

• Bumped compileSdk 35 → 36 across all plugin Android modules in one commit (22 packages).
• Included google_mlkit_commons — good catch @Copilot, the repo still had it at 35, so the alignment is now real in-tree (not just relative to the published AAR).

On testing with the example app: this is a build-config-only change (compileSdk only sets the compilation target; no source/API changes), and every module now uniformly targets 36 to match the Google native AARs. I haven't been able to run the full example matrix in my environment yet — happy to add example build results, or defer to CI if that already covers it.

Thank you @fbernaly for the quick review and merge! 🙏 Much appreciated — great to see the whole monorepo aligned on compileSdk 36 ahead of AGP 9. Looking forward to the pub.dev release.

For now pull the code hardcoding your yaml pointing to the repo. I do not have an ETA for the next release. I am trying to resolve some issues with SPM before releasing a new version.

Thanks @fbernaly, much appreciated — and thanks for merging it into develop. Understood on the release timing; no problem, I'll point my pubspec at the develop branch via a git dependency override in the meantime and switch back to a pub.dev version once you cut the next release (good luck with the SPM work). Happy to help test a release candidate if that's useful.
