* 在方法通道上调用方法invokeMethod
* methodName 方法名称

* res 原生发给Flutter的参数

/*

* 接收methodHandler 接收原生给flutter发送的信息
*/

在MainActivity.kt中配置通道

/**

*/
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

}
小红书sdk配置
- 从小红书分享开放平台下载sdk
- 将.arr包复制到libs文件夹下
- 引入.arr包
在android>app目录下的build.gradle中配置implementation fileTree(dir: 'libs', includes: ['*.aar'])
另一种引入方式
在android目录下的build.gradle中配置flatDir { dir 'libs' }
android>app>build.gradle中配置implementation(name:'xhssharesdk-1.1.6', ext:'aar')
