flutter项目提示 Superclass has no method named ‘inheritFromElement‘等错误解决
完整错误信息如下：/D:/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); ^^^^
