[webview_flutter_wkwebview] Roll back iOS and macOS versions by jmagman · Pull Request #13354 · flutter/packages

jmagman · 2026-10-20T17:53:20Z

Revert part of #13294 that updated the iOS and macOS versions. Re-add the availability checks. Still fix the SecTrustGetCertificateAtIndex deprecation issue.
Due to Swift Package Manager issue flutter/flutter#194864, this broke plugins with dependencies targeting lower versions.

Unblocks flutter/flutter#194871

Code Review

This pull request restores the minimum supported versions for webview_flutter_wkwebview to iOS 13 and macOS 10.15, introducing version availability checks and fallback behaviors across several platform APIs. The review feedback suggests safely unwrapping certificates in SecTrustProxyAPIDelegate.swift to avoid potential crashes, ensuring both branches of the version check are tested in PreferencesProxyAPITests.swift, and adding macOS version checks to the SecTrustProxyAPITests.swift override.

override: no versioning needed: the webview_flutter change is README‑only

It should be safe to re-land the min OS version change as a major version change to webview_flutter_wkwebview, and then make a non-breaking change to webview_flutter to pick up that new major version.

@stuartmorgan Wouldn't this still break people who don't currently set webview_flutter_wkwebview in their pubspec when they run pub upgrade?

@stuartmorgan Wouldn't this still break people who don't currently set webview_flutter_wkwebview in their pubspec when they run pub upgrade?

It shouldn't, unless there's something more complex going on here that I missed. This looks like the error we had with loosely bound google_maps_flutter_ios dependencies on the SDK, which is that SwiftPM doesn't allow Package A->Package B dependencies if A has a lower minimum OS version requirement than B. It's not that everything in the entire dependency set of an app has to have matching OS versions, just that direct dependencies can't violate that rule.

So I'm pretty sure that the issue here is specifically this OS constraint combined with this dependency. But fortunately the Dart package is correctly set up to express this direct dependency on the iOS implementation package, which means that if you do what I described above:

If someone who doesn't depend on google_mobile_ads runs pub upgrade, they will get the latest version of everything.
If someone who does depend on google_mobile_ads (and doesn't otherwise depend directly on the implementation package) runs pub upgrade, they will stay on webview_flutter_wkwebview 3.x and slightly older version of webview_flutter.

It will be the case that if someone tries to set up a new app with the latest version of webview_flutter and google_mobile_ads, they will get a resolver failure until google_mobile_ads updates to allow webview_flutter_wkwebview 4.x, but that's just business as usual for major versions working their way through the ecosystem. Existing working apps won't be broken.
