如何导入SDK以使用插件

下载SDK导入

Android

1. 将libs文件夹添加到项目的Android/app目录底部，并复制appguard-{VERSION}.aar文件。

   dependencies {
       implementation files("libs/appguard-0.2.0.aar")
   }
   

iOS

1. 使用Open in Xcode打开项目中的ios目录，或在Xcode中加载Runner.xcworkspace。
2. 将AppGuard.xcframework拖放到Runner目标中。
3. 在弹出的Choose options for adding these files:对话框中，勾选Copy items if needed，并确保在Add to targets中选择了Runner目标。
4. 确认AppGuard.xcframework已作为Do Not Embed添加到Runner目标的General/Frameworks, Libraries, and Embedded Content部分。
