### 复现的平台

Both

### Flutter SDK版本

3.0.0

### FlutterBoost版本

4.4.0

### 是否延迟初始化FlutterBoost

No

### 解决方案

Start by reproducing the first-entry TabBarView white screen in the reported iOS setup and inspect the stack trace at Flutter's page_view.dart, especially _PagePosition.applyViewportDimension, with the surrounding viewport layout calls. Done means the page opens on the first attempt without a white screen or the reported null-check exception.
