flutter android 无法运行的情况

flluter 部分控件支持安卓X后，在安卓手机上无法运行。AS单独打开 android项目，产生以下提示。

Warn

WARNING:API'variantOutput.getPackageApplication()'is obsoleteandhas been replaced with'variant.getPackageApplicationProvider()'.It will be removed at theendof2019.For more information, seehttps://d.android.com/r/tools/task-configuration-avoidance.To determine what is calling variantOutput.getPackageApplication(), use -Pandroid.debug.obsoleteApi=trueon the command line to display a stack trace.AffectedModules:app

警告信息说 APIvariantoutput.getPackageApplication()已过时，并且已被替换为variant.getPackageApplicationProvider()，将于2019年底移除。尽管如此，我们还是不知道具体哪个地方的方法过时了，根据后面提示在gradle.properties中配置android.debug.obsoleteApi=true来查看详细的调试信息：

WARNING:API'variantOutput.getPackageApplication()'is obsoleteandhas been replaced with'variant.getPackageApplicationProvider()'.It will be removed at theendof2019.For more information, seehttps://d.android.com/r/tools/task-configuration-avoidance.REASON:Calledfrom:E:\MyApp\app\flutter.gradle:422WARNING:Debugging obsolete API calls can take time during configuration. It's recommended to not keep it on at all times.

Affected Modules: app

虽然乍看和之前的日志差不多，但是这次却明确告诉我们过时方法的具体位置：flutter sdk\flutter.gradle:422。getPackageApplication()这里引用了过时方法。

flutter.gradle

注释掉422行即可，看判断，基本不影响目前的情况，后期修复可能会发生变化。
