即使我的答案不会被接受为正确答案，我只是觉得所有这些答案导致我有更多的问题，这里是我如何解决它

Get Sublime Text (crazy, right? No, just follow my steps) Click on file and select open folder, then choose the folder of the project you are working on Now click on Find from the Tabs, and select find in files or just do Ctrl + Shift + F (for Windows users, for mac users you already know the drill) Now copy and paste exactly the name of the package you want to change in the Find section and paste in the replace section what you would like to replace the package name with. Click on FIND (do not click on REPLACE just yet). Now clicking on Find lists all available package name in your project which matches your search criteria, if you are satisfied with this then repeat from no. 3 but this time click on REPLACE. Rebuild your project and have fun

结论:一个简单的查找和替换程序就可以解决这个问题，我强烈推荐Sublime Text 3。

根据官方的flutter文档，您只需要在app/build中更改ApplicationId。gradle目录。然后你只需要构建你的apk, manifest文件的包名将根据你在build.gradle中更改的ApplicationId进行更改。由于在构建apk和谷歌播放时的颤扑，都考虑从build.gradle中的ApplicationId。这个解决方案对我很有效。

但是，在更改包名时应该谨慎。

另外，在重新上传应用程序时，应该小心，因为它与之前上传的应用程序的ID相匹配。
