Change Android package name

Changing the Android package name is required for Play Store deployment or project cloning. Here’s how to do it safely and cleanly.

Method 1: Using the rename Package #

This is the simplest and fastest way.

🔧 Step-by-Step: #

1. Activate the rename tool:

flutter pub global activate rename

2. Run the rename command:

flutter pub global run rename --bundleId com.yourcompany.yourapp

This automatically updates:

• AndroidManifest.xml
• build.gradle
• Kotlin/Java package paths
• MainActivity.kt

Method 2: Manual Way #

Recommended when you want full control or can’t use third-party tools.

Change directory structure #

If your current path is:

android/app/src/main/kotlin/com/example/yourapp

and your new package is:

com.yourcompany.appname

Then change folder names accordingly:

android/app/src/main/kotlin/com/yourcompany/appname

Update the package name in these files: #

• android/app/src/main/AndroidManifest.xml

<manifest package="com.yourcompany.appname">

• android/app/build.gradle

defaultConfig {
    applicationId "com.yourcompany.appname"
}

• android/app/src/main/kotlin/.../MainActivity.kt
  Change the package line at the top:

package com.yourcompany.appname

Clean and rebuild: #

flutter clean
flutter pub get
flutter run

📝 Notes: #

• Ensure your keystore and signing configs match the new package if you’re publishing.
• Double-check any deep links, Firebase setups, or other integrations that rely on the old package name.
