Я пытался создать приложение flutter. Но при экспорте/сборке возникла ошибка. Сообщение об ошибке при построении:

 Launching libmain.dart on Android SDK built for x86 in debug mode... libmain.dart:1 C:devbmiandroidappsrcmainAndroidManifest.xml Error:  Package name 'BMI' at position AndroidManifest.xml:2:5-18 should contain at least one '.' (dot) character  FAILURE: Build failed with an exception.  * What went wrong: Execution failed for task ':app:processDebugMainManifest'. gt; Manifest merger failed : Package name 'BMI' at position AndroidManifest.xml:2:5-18 should contain at least one '.' (dot) character   * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.  * Get more help at https://help.gradle.org  BUILD FAILED in 21s Exception: Gradle task assembleDebug failed with exit code 1 Exited (sigterm)  

andriodmainifest.xml:

 lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"  package="BMI"gt;  lt;!-- Flutter needs it to communicate with the running application  to allow setting breakpoints, to provide hot reload, etc.  --gt;  lt;uses-permission android:name="android.permission.INTERNET"/gt; lt;/manifestgt;  

Ошибка связана с именем вашего пакета, указанным в файле манифеста. Вы можете добавить имя пакета как com.bmi или так далее. Пожалуйста, обратитесь к добавленному ниже файлу манифеста из моего проекта.
