我正在尝试在我的应用中使用Flavors。我遵循了各种指南，但每次都遇到相同的构建问题（由于实际上每篇博客文章和SE问题都引用了相同的文章和资源，我不会再重复说明）。
为了调试，我决定简化问题，并开始了一个新项目（普通样例项目），并添加了只有一个元素的各种口味：应用程序。这起作用了。各种其他更复杂的属性，例如将res/values/strings.xml用于应用程序标签，也运行良好。
然后我尝试使用最简单的Flavor设置来构建我的应用程序，根据以下grade.build，但迅速失败并出现了相同的错误。
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。这已经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
Using hardware rendering with device Android SDK built for x86. If you get graphics artifacts, consider enabling software rendering with "--enable-software-rendering".

当通过flutter run --flavor dev -t lib/main-dev.dart启动不包含任何自定义属性的“dev”构建时，它会进行构建和运行。
使用--verbose运行的有趣部分如下所示：

请注意，如果我从“qa”口味中删除applicationID，则可以构建。 同样，一旦将applicationId添加到dev flavor中，相同的问题就会出现，正如我所说，这个问题在标准的flutter示例项目中不存在（实际上，使用简单的项目进行测试的结果使我能够成功地在每个flavor基础上设置字符串资源和启动器图标）。
