Purpose

Production-grade voice + video calling for Flutter UIKit v6 (stable, Bloc-based). Loaded by cometchat-calls when framework === "flutter" and flutter_version === "v6". Operates in two modes:

Standalone — calls is the product. Chat SDK + Calls SDK without the v6 UI Kit (rare today, since the UI Kit ships calling bundled). Custom call screens on the SDKs.
Additive — calls layered onto an existing v6 chat integration. The v6 UI Kit ships call widgets in the same package (cometchat_chat_uikit) — no extra dependency. The skill enables calling on UIKitSettings, calls CometChatUIKitCalls.init() in the chat-init success callback, mounts the global incoming-call overlay at app root.

Read these other skills first:

cometchat-calls — dispatcher (modes, hard rules, anti-patterns)
cometchat-flutter-v6-core — UIKitSettings, init/login order (CHAT_INIT_BEFORE_CALLS_INIT is THE rule)
cometchat-flutter-v6-events — Bloc event streams + listener registration

V6 vs V5 difference (critical for migration):

V6 — single cometchat_chat_uikit package (calls bundled in)
V5 — cometchat_chat_uikit + cometchat_calls_uikit (separate)
V6 uses Bloc; V5 uses GetX
V6 CometChatUIKitCalls.init(appId, region) must run AFTER CometChatUIKit.init() succeeds; V5 hides this via CometChatCallingExtension
