问题是我试图为Flutter应用程序构建一个appbundle，但是当我搜索有关错误的结果时却崩溃了，但没有发现希望有人能提供帮助的地方。
注意：该应用程序可以启动，并且可以在IOS和Android上完美运行，但是不能在其中任何一个上构建。我将为Ios问题发布一个帖子，并在完成时在此处链接它。 “链接”
您可以在下面找到“ flutter doctor -v”和“ flutter build appbundle -v”的结果。

问题在日志中
Minimum supported Gradle version is 5.4.1. Current version is 4.10.2.
If using wrapper, try editing the distributionUrl in
/Users/axel/Documents/CSC/flutter-app/android/gradle/wrapper/gradle-wrapper.properties to gradle-5.4.1-all.zip
将gradle版本升级到5.4.1
答案 1 :(得分：0)
好的，所以我的问题是我18岁时支持的最小sdk是21及更高。
所以解决方案是更改minSDKVersion：
minSdkVersion 18
到
minSdkVersion 22
