我正在尝试使用“ flutter build apk”构建项目，并且遇到以下错误：
在我的项目中，我使用的是flutter_youtube插件：flutter_youtube：^ 1.1.4
我不确定此错误的含义以及如何解决。
失败：构建失败，并出现异常。
出了什么问题：任务'：flutter_youtube：verifyReleaseResources'的执行失败。

# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
fonts:

在Android Studio中打开您的项目。在左侧，转到您添加的每个依赖项项目，打开build.gradle文件。每个“ compileSdkVersion”都应该为28。这为我解决了这个问题！
答案 1 :(得分：0)
在./android/app/build.gradle和compileSdkVersion更新到28中。您的其中一个库的项目引用的资源仅添加到API 28中，因此您无法继续使用版本27。
