app:compileFlutterBuildRelease 构建应用程序颤振时出错

Question

在源代码中运行“flutter pub get”... 5.9 秒正在运行 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，出现异常。

• 在哪里：

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

• 什么地方出了错：

任务 ':app:compileFlutterBuildRelease' 执行失败。

进程 'command 'C:\src\flutter\bin\flutter.bat'' 以非零退出值 1 结束

• 尝试：

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。使用 --scan 运行以获得完整的见解。

Answer 1

遇到同样的问题。我找到flutter build appbundle --verbose了根本原因。它基于自定义图标，这是我很久以前使用http://fluttericon.com/构建的。

所以有3种可能的解决方案：

1. 添加标志“--no-tree-shake-icons”
2. 删除自定义图标
3. 再次重新生成自定义图标

一切都会成功！

Answer 2

我认为这一行显示了错误：

Codepoint 58848 not found in font, aborting.

检查你的pubspec.yaml并看看这个错误是否来自任何库。另外，您的代码是否在调试模式下工作？您是否在 pubspec 文件中添加了任何字体？
