Flutter 2 build project: Error: The method 'SpinKitPouringHourglass' isn't defined for the class '_LoadingIndicatorState'

Question

我正在尝试使用 android studio 开始我的项目，但在昨天正常运行时发生错误。

AppData/Local/Pub/Cache/hosted/pub.dartlang.org/flutter_easyloading-3.0.0/lib/src/widgets/indicator.dart:166:22: Error: The method 'SpinKitPouringHourglass' isn't defined for the class '_LoadingIndicatorState'.
 - '_LoadingIndicatorState' is from 'package:flutter_easyloading/src/widgets/indicator.dart' ('/C:/Users/[MYUSER]/AppData/Local/Pub/Cache/hosted/pub.dartlang.org/flutter_easyloading-3.0.0/lib/src/widgets/indicator.dart').
Try correcting the name to the name of an existing method, or defining a method named 'SpinKitPouringHourglass'.
        _indicator = SpinKitPouringHourglass(
                     ^^^^^^^^^^^^^^^^^^^^^^^

我应该怎么做才能解决这个错误？

Answer 1

您正在使用插件不存在的方法：flutter_easyloading。
Flutter 容易加载是个问题。

晚上好

Answer 2

我也有同样的疑问。 flutter_easyloading 之前运行良好。所以我找到“导入 'package:flutter_spinkit/flutter_spinkit.dart';”在 indicator.dart 在 flutter_easyloading 3.0.0。但是 flutter_spinkit 已经发布了新版本 5.1.0 并查看了 ChangeLog，我找到了日志“Renamed SpinKitPouringHourglass -> SpinKitPouringHourGlass for correctness”。

是的，flutter_easyloading 也必须修改以修复此错误。
