尽可能简单地使用这个change_app_package_name包首先添加依赖

 dev_dependencies: 
  change_app_package_name: lates version

然后执行这个命令

flutter pub run change_app_package_name:main com.new.package.name

更改pubspec中的name属性。Yaml(第一行)

对于apk的名称，修改AndroidManifest.xml中的android:label

使用以下包，用单一命令更改应用程序包名称。它使这个过程非常简单和快速。

颤振pub运行change_app_package_name:main com.new.package.name

我认为这不是解决这个问题的正确办法。但是您可以用您想要的包名创建一个新项目，然后从现有项目中将所有源文件复制到新项目中。

**注意:你也必须复制pubspec的所有内容。在firebase和其他api的情况下，这个解决方案可能有点冗长。

这是我如何重命名包为ios和android

Go to build.gradle in app module and rename applicationId "com.company.name" Go to Manifest.xml in app/src/main and rename package="com.company.name" and android:label="App Name" Go to Manifest.xml in app/src/debug and rename package="com.company.name" Go to Manifest.xml in app/src/profile and rename package="com.company.name" Go to app/src/main/kotlin/com/something/something/MainActivity.kt and rename package="com.company.name" Go to app/src/main/kotlin/ and rename each directory so that the structure looks like app/src/main/kotlin/com/company/name/ Go to pubspec.yaml in your project and change name: something to name: name, example :- if package name is com.abc.xyz the name: xyz Go to each dart file in lib folder and rename the imports to the modified name. Open XCode and open the runner file and click on Runner in project explorer. Go to General -> double click on Bundle Identifier -> rename it to com.company.name Go to Info.plist click on Bundle name -> rename it to your App Name. close everything -> go to your flutter project and run this command in terminal flutter clean
