“ @required”注释为错误而不是警告

Question

现在在Flutter项目中，当我使用注释构造函数参数@required并在实例化构造函数时忘记它时，我从IDE收到一个轻微警告，要求该参数。

我希望将其显示为来自IDE的实际错误。有没有办法analysis_options.yaml将其设置为错误而不是警告？

Answer 1

在analyzer_options.yaml添加

analyzer:
  errors:
    missing_required_param: error

之前

 $ flutter analyze
Analyzing flutter_0_generic...                                   

   info • The parameter 'onPressed' is required • lib/main.dart:49:33 • missing_required_param

1 issue found. (ran in 2.2s)

后

 $ flutter analyze
Analyzing flutter_0_generic...                                   

  error • The parameter 'onPressed' is required • lib/main.dart:49:33 • missing_required_param

1 issue found. (ran in 1.8s)
