Hi, thank you so much for sharing this script. I have one question, Can i deploy the flutter aar into jfrog artifactory with this script? Thanks.

@ahmdmau I have no idea, but you can refer https://jfrog.com/knowledge-base/how-to-publish-build-info-and-artifacts-from-a-gradle-android-project-into-artifactory/ to modify this script.
./gradlew build确实找不到，应该是先进入.android目录吧？
目录格式如下：

@xymelon 第一条评论有 cd .android 这个步骤的
Hi Vove7，在 flutter 3.3.9 和 3.4.0-38.pre1 上这个脚本已经不能工作。
直接执行脚本编译成功后会出现如下错误：
将 flutter_aar_upload.gradle 中第14行由 project.apply plugin: "maven"修改为 project.apply plugin: "maven-publish" 后，编译成功后又会出现如下错误：
请教下该如何修改呢？
@xymelon 第一条评论有 cd .android 这个步骤的
感谢回复，看第一条评论的脚本，是先进入的上层目录cd ..，再执行的./gradlew build，上层目录中找不到./gradlew，导致出错。
然后再问下，执行./gradlew build目的在哪？
#!/usr/bin/env sh
flutter pub get
cd ..
./gradlew build
cd .android

可以参考下这篇博客，按照之前版本思路来适配新版flutter gradle，当时flutter版本好像是2.x
https://blog.csdn.net/qq_37299249/article/details/115012889
感谢回复和提供思路，我基于最新的 flutter 3.3.9 stable 版的 aar_init_script.gradle 文件做了修改，实测可以上传到远程私有仓库，如果有遇到这个问题的朋友可以参考下。
flutter_aar_build_upload.gradle
@wqandroid make sure you're passing is-plugin as parameter when you run your script
感谢两位 @Vove7 @xiejianchao提供的Flutter Version: 2.x and 3.x，我已经成功使用 3.x flutter_aar_build_upload.gradle上传到本地的nexus了。
