我创建了一个新的颤振应用程序，但是当我第一次尝试运行颤振应用程序时，我收到以下错误

/C:/dev/flutter/packages/flutter/lib/src/painting/_network_image_io.dart:130:7: Error: The getter 'Arethrow' isn't defined for the class 'NetworkImage'.
 - 'NetworkImage' is from 'package:flutter/src/painting/_network_image_io.dart' ('/C:/dev/flutter/packages/flutter/lib/src/painting/_network_image_io.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'Arethrow'.

      Arethrow;

/C:/dev/flutter/packages/flutter/lib/src/painting/_network_image_io.dart:85:20: Error: A non-null value must be returned since the return type 'Codec' doesn't allow null.
 - 'Codec' is from 'dart:ui'.

  Future<ui.Codec> _loadAsync(
                   ^

我使用 VSCode 作为我的编辑器。我可以使用 flutter run 命令从命令行成功运行该应用程序。但是我无法使用 F5 按钮或开始调试命令运行该应用程序。可能是什么问题？
