用flutter运行代码的时候出错，错误信息如下：
Launching lib\main.dart on Chrome in debug mode...
org-dartlang-app:/web_entrypoint.dart:13:18: Error: Getter not found: 'main'.
if (entrypoint.main is _UnaryFunction) {
^^^^
org-dartlang-app:/web_entrypoint.dart:14:24: Error: Getter not found: 'main'.
return (entrypoint.main as _UnaryFunction)(<String>[]);
^^^^
org-dartlang-app:/web_entrypoint.dart:16:22: Error: Getter not found: 'main'.
return (entrypoint.main as _NullaryFunction)();
^^^^
