dartanalyzer在入门教程中报告错误

Question

在flutter.io/get-started/codelab上发现的此片段上运行dartanalyzer会产生以下错误：

$ dartanalyzer lib/main.dart
Analyzing lib/main.dart...
  error • The function 'MyApp' isn't defined at lib/main.dart:3:23 • undefined_function
  error • 'MaterialApp' isn't a function at lib/main.dart:8:12 • invocation_of_non_function

  error • 'Text' isn't a function at lib/main.dart:12:18 • invocation_of_non_function
  error • 'Center' isn't a function at lib/main.dart:14:15 • invocation_of_non_function
  error • 'Text' isn't a function at lib/main.dart:15:18 • invocation_of_non_function
7 errors found.

$ dartanalyzer --version
dartanalyzer version 1.24.3

我该怎么做才能使分析仪正确运行？

Answer 1

对于Flutter项目，而不是运行dartanalyzer，应运行flutter analyze。 Flutter附带了它自己的SDK，因此常规的dart分析器如果没有一些额外的配置（该命令提供的配置）就无法工作。
