CometChatMessageHeader的appBarOptions中通话按钮不显示问题

已完成的初始化操作 #

1. CometChatApp 初始化 #

AppSettings appSettings = (AppSettingsBuilder()
      ..subscriptionType = CometChatSubscriptionType.allUsers
      ..region = Env.cometChatRegion
      ..autoEstablishSocketConnection = true)
    .build();

CometChat.init(Env.cometChatAppId, appSettings,
    onSuccess: (String successMessage) {
  debugPrint(
      "CometChat initialization completed successfully  $successMessage");
}, onError: (CometChatException excep) {
  debugPrint(
      "CometChat initialization failed with exception: ${excep.message}");
});

2. CometChat UIKit 初始化 #

UIKitSettings uiKitSettings = (UIKitSettingsBuilder()
      ..subscriptionType = CometChatSubscriptionType.allUsers
      ..autoEstablishSocketConnection = true
      ..region = Env.cometChatRegion
      ..appId = Env.cometChatAppId
      ..authKey = Env.cometChatAuthKey
      
      ..extensions = CometChatUIKitChatExtensions.getDefaultExtensions())
    .build();

CometChatUIKit.init(
    uiKitSettings: uiKitSettings,
    onSuccess: (String successMessage) {
      debugPrint(
          "CometChatUIKit initialization completed successfully  $successMessage");
    },
    onError: (CometChatException e) {
      debugPrint(
          "CometChatUIKit initialization failed with exception: ${e.message}");
    });

当前消息功能正常，可在用户间发送、接收文本及媒体消息。

问题描述 #

按照文档要求在UIKit初始化代码中添加..callingExtension = CometChatCallingExtension()后，未达到预期效果：

成功初始化聊天和通话UIKit后，通话按钮将添加到CometChatMessageHeader的appBarOptions中，允许用户向其他聊天参与者发起语音或视频通话。此外，通话UIKit还提供呼入、呼出和进行中通话的完整功能UI组件。

实际情况是：AppBar中仅能看到默认的ProfileInfo按钮，未出现通话按钮。

已尝试的解决方法 #

• 添加Flutter SDK（聊天和通话）的单独初始化方法
• 切换至文档推荐的旧版Flutter SDK
  以上操作均未解决问题。

依赖配置（pubspec.yaml） #

cometchat_chat_uikit: ^4.0.0-beta.2
cometchat_sdk: ^4.0.0-beta1
cometchat_calls_uikit: ^4.0.0-beta.1
