papyrus_macos 0.1.1

macOS WKWebView backend for Papyrus, a secure policy-driven federated WebView plugin for Flutter apps.

papyrus_macos

macOS WKWebView implementation package for Papyrus.

The native implementation aligns with iOS WKWebView behavior and adds macOS handling for print, keyboard, accessibility, context menus, and scroll behavior.

Sandboxed macOS runners must include com.apple.security.network.client in both DebugProfile.entitlements and Release.entitlements so WKWebView can load content reliably.

Papyrus uses the desktop overlay path by default on macOS. Set PAPYRUS_USE_NATIVE_MACOS_PLATFORM_VIEW=true only when explicitly testing the AppKit platform-view path.

macOS distribution

WKWebView is a system framework bundled with macOS — no WebKit redistributable is required in the app bundle. The minimum macOS version for the WKWebView features used by Papyrus is 10.15 Catalina.

Distribution type	Required entitlement	Notes
Direct distribution (DMG / PKG)	com.apple.security.network.client	Add to both Debug/Profile and Release entitlement files
Mac App Store	com.apple.security.network.client	Required for sandbox; add via Xcode capabilities
Notarized app	com.apple.security.network.client	Hardened runtime must also be enabled

No additional runtime installer is needed. WKWebView receives security updates as part of macOS system updates — the host app inherits those automatically.
