A tencent COS Upload Plugin.
Recently, I've been using flutter to develop an app that uses the Tencent COS to upload pictures.
I a plugin package named tencent_cos https://github.com/OpenFlutter/tencent_cos, when i added it to the project, but found it has bug.
Then I found another plugin fw_cos https://pub.dev/packages/fw_cos, and it has bug too, and both of them are not null-safe.
So I create this plugin.
