Flutter音乐播放器项目模拟器运行失败，Isolate创建异常求助

我按照YouTube教程开发Flutter音乐播放器项目，前期运行正常，后期修改后项目无法启动。执行flutter run时出现以下错误日志：

E/flutter ( 3098): [ERROR:flutter/runtime/dart_isolate.cc(146)] Could not prepare isolate.
E/flutter ( 3098): [ERROR:flutter/runtime/runtime_controller.cc(487)] Could not create root isolate.
E/flutter ( 3098): [ERROR:flutter/shell/common/shell.cc(686)] Could not launch engine with configuration.

我认为可能出错的文件为main.dart、song_page.dart、home_page.dart，代码如下：

已尝试flutter clean、检查依赖、修改疑似出错的文件，但代码无语法错误，问题仍未解决，恳请技术帮助。
