我正在尝试在我的应用程序中使用风味。我遵循了各种指南，但每次都因同样的问题而无法构建。 （因为基本上每个博客文章和 SE 问题都引用相同的文章和资源，所以我不会再这样做了）
为了调试，我决定简化问题并启动一个新项目（正常示例项目），并添加风味，每种风味只有一个元素：应用程序。这奏效了。各种其他更复杂的属性，例如使用 res/values/strings.xml 作为应用程序标签也可以正常工作。
然后，我使用我的应用程序尝试了最简单的风味设置，其中的grade.build如下所示，然后很快就失败并出现相同的错误。
flavorDimensions "app"
productFlavors {
dev {
dimension "app"
}
qa {
dimension "app"
applicationId "com.example.app1"
}
}
注意：我还使用单独的入口点来实现运行时配置。这按预期工作并且已经使用了一段时间。
johan@komp:~/AndroidStudioProjects/parent_lite$ flutter run --flavor qa -t lib/main-qa.dart

当启动不包含任何自定义属性的“dev”风格时（通过flutter run --flavor dev -t lib/main-dev.dart）它构建并运行。
使用 --verbose 运行的有趣部分如下

请注意，如果我从“qa”风格中删除 applicationID，它就会构建。另外，当我将 applicationId 添加到开发风格时，同样的问题也出现了，正如我所说，标准 flutter 示例项目不存在这个问题（事实上，简单项目的测试结果允许我设置字符串资源）和启动器图标成功）
