背景
flutter 項目在安卓機編譯時報錯，提示/Users/vz4qt9/fvm/versions/3.7.12/bin/cache/artifacts/engine/android-arm/flutter.jar找不到，而無論使用 flutterMode 為 debug、profile、release 始終 /Users/vz4qt9/fvm/versions/3.7.12/bin/cache/artifacts/engine/ 都只有 android-arm-profile、android-arm-release、android-arm64-profile、android-arm64-release、android-x64-profile、android-x64-release 并沒有 android-arm

嘗試了一些操作后，再次編譯，問題仍然存在。例如：
- 清除gradle緩存
./gradlew clean - 清除 fvm 緩存
rm -rf /Users/vz4qt9/fvm/versions/3.7.12/bin/cache
都無法解決問題。
直到使用了fvm flutter precache --android才觸發(fā)了fvm下載android-arm文件夾。
Flutter 為 Android 平臺提供了針對不同 CPU 架構 和 構建模式 (Build Mode) 的工件
- 按構建模式劃分：
Debug (調(diào)試模式): 用于開發(fā)和熱重載。
Profile (性能模式): 用于分析應用性能。
Release (發(fā)布模式): 用于打包發(fā)布到應用商店。- 按 CPU 架構劃分：
arm: 32位 ARM 架構（例如你之前用的 PGEM10 設備）。
arm64: 64位 ARM 架構（現(xiàn)在絕大多數(shù)手機）。
x64: 64位 Intel/AMD 架構（主要用于 Android 模擬器）。
- android-arm 這個名字代表：
android: 平臺是安卓
arm: 架構是 32位 ARM
(無后綴): 構建模式是 Debug
fvm flutter precache --android 介紹
這個命令的作用是提前下載（Pre-cache）指定 Flutter 版本（3.7.12）在開發(fā)和構建 Android 應用時所需的所有引擎工件（engine artifacts）。flutter precache --android 命令的職責就是“把所有 Android 相關的工件都準備好”
