[Bug]: flutter => flutter 增加模型传参

### 请描述遇到的问题，以及您所期望的正确的结果

在flutter和flutter相互之间传参 ，能不能增加模型传参？ 非原生跳转flutter的场景下 ， 目前都是发送发 model.toJson , 接收方 ClassModel.fromJson 通过json互相转换传参的 ，希望增加flutter -> flutter 之间跳转传参

### 请说明如何操作会遇到上述问题

### 复现的平台

iOS

### Flutter SDK版本

3.22.3

### FlutterBoost版本

5.0.2

### 是否延迟初始化FlutterBoost

No

### 解决方案

The issue names FlutterBoost 5.0.2 and Flutter-to-Flutter navigation, but no source file, test, or reproduction code is provided. Start by locating the navigation argument handling and reviewing the existing model.toJson/ClassModel.fromJson flow; done should be defined as passing model objects between Flutter screens without manual JSON conversion, with coverage for iOS.
