Flutter Android应用Release模式偶现白屏问题求助

我的Flutter Android应用在Debug模式下运行完全正常，但配置签名密钥完成Release构建后，启动时大部分情况下显示空白白屏，仅每7-8次安装中有1次能正常运行。我已尝试关闭R8代码混淆与资源压缩、添加Flutter错误监听等方案，均未解决问题，寻求技术支持。

main.dart 代码 #

import 'core/theme/theme_constants.dart';
import 'core/theme/theme_manager.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(
    const BetterFeedback(
      child: MyApp(),
    ),
  );
}

ThemeManager themeManager = ThemeManager();

class MyApp extends StatefulWidget {
  const MyApp({super.key});


  @override
  State<MyApp> createState() => _MyAppState();
}


class _MyAppState extends State<MyApp> {

  @override
  void initState() {
    super.initState();
    themeManager.addListener(themeListener);
    UserManager().loadData().then((value) => themeManager.toggleTheme(UserManager().isDark));
    SystemChrome.setPreferredOrientations([
      DeviceOrientation.portraitUp,
    ]);
  }

  @override
  void dispose() {
    themeManager.removeListener(themeListener);
    SystemChrome.setPreferredOrientations([
      DeviceOrientation.landscapeRight,
      DeviceOrientation.landscapeLeft,
      DeviceOrientation.portraitUp,
      DeviceOrientation.portraitDown,
    ]);
    super.dispose();
  }


  void themeListener() {
    if (mounted) {
      setState(() {});
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: '泰美影视',
      debugShowCheckedModeBanner: false,
      theme: lightTheme,

      home: UpgradeAlert(
        showIgnore: false,
        child: const SplashScreen(),
