android - 应用程序 :compileFlutterBuildRelease error while building app flutter

Question

在源代码中运行“flutter pub get”... 5.9s
正在运行 Gradle 任务“bundleRelease”...
在字体中找不到代码点 58848，正在中止。
目标 aot_android_asset_bundle 失败:FontSubset 错误:字体子集设置失败，退出代码为 -1。
构建失败。
FAILURE:构建失败并出现异常。

地点:

脚本 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' 行:838

出了什么问题:

任务 ':app:compileFlutterBuildRelease' 执行失败。

Process 'command 'C:\src\flutter\bin\flutter.bat'' finished with non-zero exit value 1

试试:

使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。

遇到了同样的问题。
与 flutter build appbundle --verbose我找到了根本原因。它基于自定义图标，这是我很久以前用 http://fluttericon.com/ 构建的。 .
所以有3种可能的解决方案:

添加标志“--no-tree-shake-icons”

删除自定义图标

再次重新生成自定义图标

一切都会奏效!
