MissingPluginException - shared_preferences、image_picker 等在删除 flutter_branch_sdk 时有效

编程问答 2022-05-15

问题描述

我在互联网上摸索了很长时间，无法弄清楚是什么问题以及如何处理它。如果您需要更多详细信息，请发表评论。

问题：MissingPluginException - shared_preferences（在通道 plugins.Flutter.io/shared_preferences 上没有找到方法 getAll 的实现），image_picker（没有找到方法的实现pickImage)、等

下面是我的 pubspec.yaml

我尝试了以下解决方案：

解决方案 #1 - https://stackoverflow.com/a/66417139/2456838

解决方案 #2 - 向主要方法添加了 SharedPreferences.setMockInitialValues({});。但是所有值在从本地存储中检索时都返回 null。

解决方案 #3（有效） - 如果我删除 Flutter_branch_sdk 依赖项，一切都会按预期进行。我尝试了 Flutter_branch_sdk 的所有版本，但都没有奏效。

其他解决方案 - 更新了 Flutter、dart、Android Studio 等。将所有依赖项升级到主版本。使用最新版本的 Gradle 和所有依赖项创建了一个新项目。
