颤动错误脚本'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle'行：1102

Question

您好，我有一个颤振错误，尽管我的代码中没有任何错误。这都是错误：

/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/provider-3.2.0/lib/src/delegate_widget.dart:194:18: Error: Superclass has no method named 'inheritFromElement'.
    return super.inheritFromElement(ancestor, aspect: aspect);
                 ^^^^^^^^^^^^^^^^^^
/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/provider-3.2.0/lib/src/provider.dart:259:19: Error: The method 'inheritFromWidgetOfExactType' isn't defined for the class 'BuildContext'.
 - 'BuildContext' is from 'package:flutter/src/widgets/framework.dart' ('/C:/src/flutter/packages/flutter/lib/src/widgets/framework.dart').
Try correcting the name to the name of an existing method, or defining a method named 'inheritFromWidgetOfExactType'.
        ? context.inheritFromWidgetOfExactType(type) as InheritedProvider<T>
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

错误代码

我将版本降级到1.12.15并没有窃取任何内容

重新启动电脑后我遇到了同样的问题。

尝试以下任一方法：

升级你的依赖项pubspec.yaml

或者

flutter clean那么尝试扑动flutter run

最后，如果它不起作用，您必须删除 flutter src 文件夹 Script 'C:\src\flutter并再次重新安装

确保您创建 flutter 项目的路径没有空格。
