错误：没有为类 'IOClient' 定义 getter 'hellawait'

Question

我创建并运行了一个基于位置和天气的应用。但是当我关闭 VS Code 并尝试重新安装应用程序时，出现以下错误！。 如何消除错误！。

Launching lib\main.dart on Infinix X655C in debug mode...
/C:/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.13.4/lib/src/io_client.dart:35:34: Error: Expected ')' before this.
      var ioRequest = (hellawait _inner!.openUrl(request.method, request.url))
                                 ^^^^^^

/C:/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.13.4/lib/src/io_client.dart:35:24: Error: The getter 'hellawait' isn't defined for the class 'IOClient'.
- 'IOClient' is from 'package:http/src/io_client.dart' ('/C:/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.13.4/lib/src/io_client.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'hellawait'.
      var ioRequest = (hellawait _inner!.openUrl(request.method, request.url))
                       ^^^^^^^^^
