安卓版本运行会报错，需要增加一行 namespace

[ChinaArJun]

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':amap_map'.

Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

 If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

1.3.1 手动修改插件的 build.gradle

找到 video_thumbnail 插件的源码路径，具体路径如下：
javascript 代码解读复制代码~/.pub-cache/hosted/pub.dartlang.org/video_thumbnail-/

在 video_thumbnail 插件的 android/build.gradle 中添加 namespace，例如：

android {
namespace 'xyz.justsoft.video_thumbnail'
// 其余配置...
}
