Android中集成flutter组件，按照官方文档进行：

// Include the host app project.
include ':app'                                    // assumed existing content
setBinding(new Binding([gradle: this]))                                // new
evaluate(new File(                                                     // new
  settingsDir.parentFile,                                              // new
  'my_flutter/.android/include_flutter.groovy'                         // new
))                                                                     // new

在按照官方文档操作之后，报错：Failed to apply plugin class ‘FlutterPlugin‘.

针对上面的报错，处理方式如下（该处理方式参照自https://github.com/flutter/flutter/issues/99735）：

• step1: 创建flutter_settings.gradle文件，和setting.gradle在同一个目录下

setBinding(new Binding([gradle: this]))
evaluate(new File(settingsDir.parentFile, 'flutter_module/.android/include_flutter.groovy'))

备注：flutter_module修改为自己的flutter依赖名称
eg：

setBinding(new Binding([gradle: this]))
evaluate(new File(settingsDir.parentFile, 'MySWApp/lib_flutter/.android/include_flutter.groovy'))

step2: 修改settings.gradle文件

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS)
    repositories {
        google()
        mavenCentral()
      }
}
rootProject.name = "MySWApp"
include ':app'
apply { from("flutter_settings.gradle") } // add this

重新运行就OK了
