[Bug]: 不显示flutter_boost模块

### 请描述遇到的问题，以及您所期望的正确的结果

问题：
1、集成flutter_boost，原生Android项目中一直不显示flutter_bost模块，只显示了flutter模块
2、同步过程中一直提示Namespace not specified.，实际情况是Android项目已设置namespace
3、如果不依赖flutter_boost，项目可以正常运行。

相关库版本信息
1、引入flutter_boost：4.4.0
2、flutter版本：3.13.1
3、gradle版本：gradle-8.0-bin.zip
4、setting.gradle增加引入源码
repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS)
include ':flutter_module'
setBinding(new Binding([gradle: this]))
evaluate(new File(
settingsDir.parentFile,
'flutter_module/.android/include_flutter.groovy'
))
project(':flutter_module').projectDir = new File('../flutter_module')

### 请说明如何操作会遇到上述问题

1、引入flutter_boost，执行pub get
在flutter项目中引入flutter_boost
flutter_boost:
git:
url: 'https://github.com/alibaba/flutter_boost.git'
ref: '4.4.0'
2、Android项目setting.gradle指定文件路径
include ':flutter_module'
setBinding(new Binding([gradle: this]))
evaluate(new File(
settingsDir.parentFile,
'flutter_module/.android/include_flutter.groovy'
))
project(':flutter_module').projectDir = new File('../flutter_module')
3、Android的app层级下build.gradle增加flutter源码依赖，sync项目
implementation project(':flutter')
implementation project(':flutter_boost')
4、经过以上步骤，项目中已显示flutter模块，但是一直没有flutter_boost模块，且一直提示Namespace not specified

### 在下面填入关键复现代码

```
```

### 复现的平台

Android

### Flutter SDK版本

3.13.1

### FlutterBoost版本

4.4.0

### 是否延迟初始化FlutterBoost

No

### 解决方案

Reproduce the Android integration with Flutter 3.13.1, FlutterBoost 4.4.0, and Gradle 8.0, starting with the reported sync failure. Inspect setting.gradle, the app-level build.gradle, and flutter_module/.android/include_flutter.groovy to trace why flutter_boost is absent and why the namespace warning appears. Done means the flutter_boost module is shown and the namespace warning is resolved.
