Changing App ID

In Flutter, the application ID (for Android) and bundle ID (for iOS) are essential identifiers that uniquely distinguish your app from others in the app ecosystem.

It’s important to customize these identifiers to match your app's branding and ensure they are unique, especially when publishing your app to the Google Play Store or Apple App Store.

In this guide, we will demonstrate how to change the application ID and bundle ID using the rename package, which simplifies the process by automating the necessary updates across your project files.

• Run the following command to change the applicationId and bundle Identifier for Android and Ios respectively.

rename setBundleId --targets ios,android --value "com.example.bundleId"

If you face any error while running above command. Try prefixing 'flutter' before the command like below.

flutter rename setBundleId --targets ios,android --value "com.example.bundleId"

Replace com.example.bundleId to your bundle identifier, Reference below link for more info.
