Code Review

This pull request introduces Swift Package Manager (SPM) support for the firebase_ai package on iOS and macOS and updates the example project configuration. Feedback highlights several critical issues: the record package upgrade introduces breaking changes that likely require code updates, and the macOS project file is missing a required package property for its Swift package dependency. Furthermore, the iOS configuration is now inconsistent due to the removal of CocoaPods build phases and the MinimumOSVersion key, and the migration metadata incorrectly replaced the Android platform entry instead of appending macOS.

I am having trouble creating individual review comments. Click here to see my feedback.

packages/firebase_ai/firebase_ai/example/pubspec.yaml (36)

The record package has been upgraded from ^5.2.1 to ^6.2.0. This is a major version update with breaking changes (e.g., the Record class was renamed to AudioRecorder). Please ensure that the example's Dart code has been updated to accommodate these changes, otherwise the app will fail to compile.

packages/firebase_ai/firebase_ai/example/macos/Runner.xcodeproj/project.pbxproj (825-828)

The XCSwiftPackageProductDependency entry for FlutterGeneratedPluginSwiftPackage is missing the package property. This property is required to link the product dependency to its corresponding package reference (781AD8BC2B33823900A9FFBB). Without it, Xcode will not be able to resolve the dependency, leading to build failures.

		78A3181F2AECB46A00862997 /* FlutterGeneratedPluginSwiftPackage */ = {
			isa = XCSwiftPackageProductDependency;
			package = 781AD8BC2B33823900A9FFBB /* XCLocalSwiftPackageReference "FlutterGeneratedPluginSwiftPackage" */;
			productName = FlutterGeneratedPluginSwiftPackage;
		};

packages/firebase_ai/firebase_ai/example/ios/Runner.xcodeproj/project.pbxproj (198-205)

The CocoaPods build phases ([CP] Check Pods Manifest.lock and [CP] Embed Pods Frameworks) were removed from the iOS target. However, the project still contains a Podfile and depends on other plugins (like firebase_core) that likely still require CocoaPods. Removing these phases will break the build for those dependencies.

packages/firebase_ai/firebase_ai/example/ios/Flutter/AppFrameworkInfo.plist (23-24)

The MinimumOSVersion key was removed from AppFrameworkInfo.plist. This key is typically required for frameworks on iOS to specify their minimum supported version. Removing it may cause issues during the build process or when submitting the app.

packages/firebase_ai/firebase_ai/example/.metadata (18-20)

The android platform entry was replaced by macos in the migration metadata. This file should track all platforms associated with the project. Removing the android entry may cause issues with Flutter's migration and upgrade tools for that platform. Please add macos as a new entry instead of replacing the existing one.

Code Review

This pull request introduces Swift Package Manager (SPM) support for the firebase_ai plugin on iOS and macOS, alongside updates to the example app's build configurations and dependencies. Feedback focuses on critical structural issues: the Package.swift files are incorrectly placed in subdirectories, which prevents automatic discovery by Flutter, and essential Firebase SDK dependencies are missing from the package definitions. Additionally, it is recommended to avoid hardcoding the library version to reduce maintenance overhead.

Looks great. You need to add firebase_ai to this: https://github.com/firebase/flutterfire/blob/main/.github/workflows/all_plugins.yaml#L139 so we can have the CI checking the SPM status as well :)
