### 解决方案

No source file, test, reproduction steps, or code sample is named. Start by reproducing the Android build failure with Flutter SDK 3.32.7 and FlutterBoost 5.0.0, then trace the missing FlutterMain reference and check whether the failure is a version-compatibility issue; done means the project builds successfully without that missing-file error.
