看闲鱼flutter，Android的Flutter依赖抽取实现的一些疑问

Question

摘自https://juejin.im/post/5b5811...编译Flutter工程。这部分主要工作是编译Flutter的dart和资源部分，可以用AOT和Bundle命令编译。echo"Cleanoldbuild"find.-d-name"build"|xargsrm-rf./flutter/bin/fluttercleanecho"Getpackages"./flutter/bin/flutterpackagesgetecho"BuildreleaseAOT"./flutter/bin/flutterbuildaot--release--preview-dart-2--output-dir=build/flutteroutput/aotecho"BuildreleaseBundle"./flutter/bin/flutterbuildbundle--precompiled--preview-dart-2--asset-dir=build/flutteroutput/flutter_assets第一个疑问：通过flutter自己的可执行文件，执行一些暴露的function。虽然clean正常执行了，但是我看bin/flutter的内容里没有clean....不知道clean这个函数到底在哪。第二个疑问：preview-dart-2这个我也没有找到在哪...，并且aot--release，bundle--precompiled这两个命令也没百度出个所以然来。感觉好像需要装aot，bundle环境？有没有了解这一块的大佬指教一下，再说破一点。谢谢了。
