颤振ObjectBox单元测试-未能加载动态库'lib/objectbox.dll‘

Question

我正在用objectBox作为DB构建我的新的颤振应用程序。

当我编写包含objectBox的单元测试时，在运行测试时会收到以下错误消息：

加载"C:\Dev\flutter_rebuild\test\db_model_test.dart"：无效参数

失败:未能加载动态库'lib/objectbox.dll'：126

Answer 1

我在https://opensourcelibs.com/lib/objectbox-dart上找到了这个，它展示了如何将包含"objectbox.dll“的内容下载到Windows中，这样测试就可以在Android中运行。

1. Dart独立programs:

- Install the packages pub get
- Install objectbox-c system-wide: 
    - macOS/Linux: execute the following command (answer Y when it asks about installing to /usr/lib)

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-dart/main/install.sh)

        - macOS: if dart later complains that it cannot find the libobjectbox.dylib you probably have to unsign the dart binary (source: dart issue):

sudo codesign --remove-signature $(which dart)

    - Windows: use "Git Bash" or similar to execute the following command

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-dart/main/install.sh)

然后将下载的lib/objectbox.dll复制到C：\Windows\System32 32\(需要管理权限)。

ObjectBox为您希望使用build_runner存储的类生成代码绑定代码。在定义了持久化实体(参见下面)之后，运行pub run build_runner build或flutter pub run build_runner build。
