Looking at the PR again... do we actually need any of the changes to this file? It looks like the only actual change is to the integration tests and the example pubspec, and those don't require publishing the package.

In that case Im gonna close this PR. And since it doesn't need a new version, the main PR's overrides can all be removed.

Doesn't it need to target the updated platform interface package though? Not sure if Im misunderstanding this line from the federated packages section

If new functionality is being added to the API surface of the app-facing package, be sure to update the version constraints of the implementation packages in its pubspec.yaml

Doesn't it need to target the updated platform interface package though?

What is "it" here? If it's google_maps_flutter_android, what part of the google_maps_flutter_android requires the new APIs added to the platform interface?

If it's the app-facing package (in the other PR), yes, because it's exporting that surface to clients.

Not sure if Im misunderstanding this line from the federated packages section

If new functionality is being added to the API surface of the app-facing package, be sure to update the version constraints of the implementation packages in its pubspec.yaml

See the explanation in the following sentence for the reason this would need to be done.

For example, if the platform interface adds a new Future<void> foo() { throw UnimplementedError(); }, and all the platforms are updated to implement foo(), and the app-facing package is updated to call foo(), we don't want a valid set of resolved packages where clients can get the updated version of the app-facing and platform interface packages, but not the implementation packages, such that everything compiles but all calls to foo() throw.

Ok got it. For android we dont't need a new version. I guess even web doesn't need a new version by the same logic since that's just a comment change?

Correct; IIRC the tooling will do the right thing with a comment-only change, but if not we can override the version check.

Similarly, the only change to this package is to a file in the example app that's not the one visible on pub.dev, so this should be exempt from versioning.

Although, why is only the example changing for iOS? Shouldn't it be using zIndexInt instead of the deprecated zIndex now, since it can't use any fractional values anyway?

You're right, not sure how that ended up getting removed or at what point. I think the reasonable thing to do would be to make ios's PlatformMarker expect an integral zIndex, so that this truncation would now be a type error to which we can pass zIndexInt

Agreed, the iOS changes look good here.

Based on the CI failure though, it appears that the Obj-C compiler flags 64-bit int assignment to 32-bit int assignment as lossy, but did not flag it when it was assigning a double to a 32-bit int. Odd, but you'll need to add an explicit cast here to make the analysis check happy.

That's seems reasonable from flags.
-Wno-float-conversion looks like it allows implicit float conversion which is what was happening
-Wshorten-64-to-32 would disallow the long to int cast that's happening at the line you pointed out
