Quick Start

Papyrus exposes a generic Flutter widget and controller for controlled native WebView rendering.

final controller = PapyrusController.create();

PapyrusView(
  controller: controller,
  configuration: PapyrusProfiles.documentViewer(),
  initialRequest: const PapyrusHtmlRequest(
    html: '<h1>Terms</h1><p>Controlled HTML content.</p>',
  ),
);

Use PapyrusProfiles.lockedDown() for untrusted static HTML and opt into more permissive policies only when the content source is trusted.

On macOS, sandboxed apps must include the com.apple.security.network.client entitlement for WKWebView to load content reliably. Add it to both DebugProfile.entitlements and Release.entitlements in the host runner.

On Windows, ensure Microsoft Edge WebView2 Runtime is installed. If it is not available, Papyrus reports webViewUnavailable with a host-readable message.
