Package name and bundle identifier

Every flutter project contains 2 Ids: package name (for android) and bundle identifier (for iOS), these ids must be unique. So, you must change them.

1. Go to android/app/src/(main, debug, profile)/AndroidManifest.xml (3 files) and search for package and replace the old package with your package.

2. Go to android/app/build.gradle and search for applicationId and replace the old package with your package.

3. Go to android app/src/main/kotlin/com/example/NourishNow/(MainActivity.kt, Application.kt) (2 files) and search for package keyword and replace the old package with your package.

4. Change the directory name from: android\app\src\main\kotlin\com\example\NourishNow to: android\app\src\main\kotlin\your\package\name (your.package.name)

iOS#

Go to ios/Runner.xcodeproj/project.pbxproj and search for: PRODUCT_BUNDLE_IDENTIFIER and replace the old bundle identifier with yours (there are 3 replacement).
