框架中不存在的类上的Futter歧义导入

Question

突然之间，我在类上收到了模棱两可的导入错误，而这些类绝对不存在于错误消息中所述的位置。例如，类的名称类似于BusinessEntityResponse (即GetUserNameResponse)，Flutter/dart在框架中将其报告为不明确。关于如何解决这个问题(尝试清除颤动)，或者为什么会发生这种情况，或者如何进行故障排除，有什么想法吗？

    "owner": "dart",
    "code": {
        "value": "ambiguous_import",
        "target": {
            "$mid": 1,

            "path": "/tools/diagnostic-messages",
            "scheme": "https",
            "authority": "dart.dev",
            "fragment": "ambiguous_import"
        }
    },
    "severity": 8,
    "message": "The name 'MyAppClassResponse' is defined in the libraries 'package:my_app/api/dto.dart' and 'package:flutter/src/widgets/framework.dart'.\nTry using 'as prefix' for one of the import directives, or hiding the name from all but one of the imports.",

    "startLineNumber": 81,
    "startColumn": 10,

}

这似乎表明了一个更大的问题，因为下面的代码行也突然抛出了编译错误：

类AppEntryWeb扩展了StatelessWidget -->类只能扩展其他类。

Answer 1

值得注意的是，这些错误似乎是在visual studio代码颤动扩展更新到3.15.0时发生的。我卸载了flutter/dart扩展，关闭了vs代码，重新打开并重新安装了它们，这似乎已经解决了这个问题。

更多信息，visual studio代码分析器问题窗口报告的信息与运行颤动分析时报告的信息不同。不知道为什么。
