如果您尝试按照此link

向现有项目添加内容，

打开您的Flutter SDK：FlutterSdk / flutter / packages / flutter_tools / gradle / flutter.gradle

在任何编辑器中打开flutter.gradle并进行以下更改

来自：

   // We know that the flutter app is a subproject in another Android app when these tasks exist.
Task packageAssets = project.tasks.findByPath(":flutter:package${variant.name.capitalize()}Assets")
Task cleanPackageAssets = project.tasks.findByPath(":flutter:cleanPackage${variant.name.capitalize()}Assets")
Task copyFlutterAssetsTask = project.tasks.create(name: "copyFlutterAssets${variant.name.capitalize()}", type: Copy) {
dependsOn flutterTasks
if (packageAssets && cleanPackageAssets) {
dependsOn packageAssets
dependsOn cleanPackageAssets
into packageAssets.outputDir
} else {
dependsOn variant.mergeAssets
dependsOn "clean${variant.mergeAssets.name.capitalize()}"
into variant.mergeAssets.outputDir
}
flutterTasks.each { flutterTask ->
with flutterTask.assets
// Include the snapshots in the assets directory.
if (flutterBuildMode != 'release' || targetPlatformValue != 'android-arm-all') {
with flutterTask.snapshots
}
}
}
  if (packageAssets) {
      String mainModuleName = "app"
     try {
               String tmpModuleName = project.rootProject.ext.mainModuleName
               if (tmpModuleName != null && !tmpModuleName.empty) {
            mainModuleName = tmpModuleName
     }
   } catch (Exception e) {
   }
 Only include configurations that exist in parent project.
 Task mergeAssets = project.tasks.findByPath(":${mainModuleName}:merge${variant.name.capitalize()}Assets")
      if (mergeAssets) {
        mergeAssets.dependsOn(copyFlutterAssetsTask)
  }
} else {
  def processResources = variant.outputs.first().processResources
  processResources.dependsOn(copyFlutterAssetsTask)
 }

如果在现有应用程序中添加了flutter，请转到flutter模块-> .android-> build.gradle。 classpath必须与Android相同

dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
    }

Flutter错误：VM快照无效，无法从设置中推断
