How to change package name in flutter?

For Android App Name

Change the label name in your AndroidManifest.xml file:

 <application
    android:name="io.flutter.app.FlutterApplication"
    android:label="TheNameOfYourApp"   

For Package Name

Change the package name in your AndroidManifest.xml (in 3 of them, folders: main, debug and profile, according what environment you want to deploy) file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package.name">

Also in your build.gradle file inside app folder

defaultConfig {
    applicationId "your.package.name"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Finally, change the package in your MainActivity.java class (if the MainActivity.java is not available, check the MainActivity.kt)

    package your.package.name;

    import android.os.Bundle;
    import io.flutter.app.FlutterActivity;
    import io.flutter.plugins.GeneratedPluginRegistrant;
    public class MainActivity extends FlutterActivity {

Change the directory name:

From:

  android\app\src\main\java\com\example\name

To:

  android\app\src\main\java\your\package\name
  

EDITED : 27-Dec-18

for package name just change in build build.gradle only

defaultConfig {
    applicationId "your.package.name"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

For iOS

Change the bundle identifier from your Info.plist file inside your ios/Runner directory.

<key>CFBundleIdentifier</key>
<string>com.your.packagename</string>

UPDATE

To avoid renaming the package and bundle identifier, you can start your project using this command in your terminal:

flutter create --org com.yourdomain appname

---

Changing name manually doesn't seem to work, throws gradle errors, well in my case it does throw error.

So I usually create a new flutter project.

I use below mentioned command to create a new flutter app

flutter create --org com.yourdomain appname

your project will have the package name as -> com.yourdomain.appname

if you just want to keep your package name as com.appname then make some changes as below

flutter create --org com appname

to add java instead of kotlin for android add -a java

flutter create -a java --org com.yourdomain appname

EDIT

If you have already created a project you can use change_app_package_name package to change the package name.

flutter pub run change_app_package_name:main com.package.appname

---

For those like me that doesn't like to change specific files, I've used https://pub.dev/packages/rename.

Using this, you simply run these commands in your terminal and your app name and identifiers will be changed.pub global run

Installing: pub global activate rename

And then, Run this command inside your flutter project root.

pub global run rename --bundleId com.example.android.app --target android

---

Android

In Android the package name is in the AndroidManifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    package="com.example.appname">

iOS

In iOS the package name is the bundle identifier in Info.plist:

<key>CFBundleIdentifier</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>

which is found in Runner.xcodeproj/project.pbxproj:

PRODUCT_BUNDLE_IDENTIFIER = com.example.appname;

Changing the name

The package name is found in more than one location, so to change the name you should search the whole project for occurrences of your old project name and change them all.

Android Studio and VS Code:

Mac: Command + Shift + F

Linux/Windows: Ctrl + Shift + F

Thanks to diegoveloper for help with iOS.

Update:

After coming back to this page a few different times, I'm thinking it's just easier and cleaner to start a new project with the right name and then copy the old files over.

This is how i renamed package for both ios and 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

---

Change name attribute in pubspec.yaml (line 1)

For the name of apk, change android:label in AndroidManifest.xml

---

As easy as possible use this change_app_package_name package first add dependencie

 dev_dependencies: 
  change_app_package_name: lates version

and then run this command

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

---

If you not started the project, this is the best possible way.

flutter create --org com.yourdomain appname

If you already created the project, install this package in your dev_dependencies and run this command.

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

This will change all the complex stuffs of changing package name in android. And right click on the iOS folder of flutter and open with Xcode.

In Xcode > select Runner > In general tab you can change the bundle Identifier.

This is the easiest possible way if you already created a project and don't know the complexity of change the package name.

Quickest and cleanest way to change your package name!

Warning:

If you have edited the contents of the folders android/, ios/ and windows/, you need to make sure you have those changes backed up somewhere before proceeding.

1. Delete your folders at the root of your flutter project:

android/

ios/

windows/

build/

Let's say you want to rename from com.oldcompany.oldproject to com.newcompany.newproject.

2. Launch the following command from the root of your project:

flutter create --org com.newcompany --project-name newproject .

PS: To make sure everything is set up correctly, you can search for your package names in your files, by running the following commands

grep --color -r com.oldcompany.oldproject *

grep --color -r com.newcompany.newproject *

---

Updated You have to change the package name to your desired package name in these five locations.

1.) src/profile/AndroidManifest.xml
2.) src/debug/AndroidManifest.xml
3.) src/main/AdroidManifest.xml
4.) app/build.gradle
     build.gradle .
       defaultConfig {
           applicationId
       }
5.) MainActivity.java or MainActivity.kt on "package"

the last step is to run flutter clean

According to the official flutter documentation you just need to change the ApplicationId in app/build.gradle directory. Then you have to just build your apk and the package name of the manifest file will be changed according to the ApplicationId you changed in build.gradle. Because of flutter while building an apk and google play both consider ApplicationId from build.gradle. This solution worked for me.

source: Official Documentation

To change package name in flutter , you have to do it for all platforms.

To make it easier, I suggest you to use rename package .

Just run this command inside your flutter project root.

pub global run rename --bundleId com.onat.networkApp

Here, com.onat.networkApp is your package name

To target a specific platform use the "-t" option. e.g:

pub global run rename --bundleId com.example.android.app -t android

You can learn more about rename package here

---

Change App Package Name with single command by using following package. It makes the process very easy and fast.

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

https://pub.dev/packages/change_app_package_name

---

Change App Package Name easily using change_app_package_name package

just add the above package in dev dependencies

dev_dependencies:
  flutter_test:
    sdk: flutter
  change_app_package_name: ^0.1.2

and run the following command, replace "com.new.package.name" with your new package name

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

Even if my answer wont be accepted as the correct answer, I just feel all these answers above caused me to have more problems here is how I fixed it

Get Sublime Text (crazy, right? No, just follow my steps) Click on file and select open folder, then choose the folder of the project you are working on Now click on Find from the Tabs, and select find in files or just do Ctrl + Shift + F (for Windows users, for mac users you already know the drill) Now copy and paste exactly the name of the package you want to change in the Find section and paste in the replace section what you would like to replace the package name with. Click on FIND (do not click on REPLACE just yet). Now clicking on Find lists all available package name in your project which matches your search criteria, if you are satisfied with this then repeat from no. 3 but this time click on REPLACE. Rebuild your project and have fun

Conclusion: a simple find and replace program is all you need to sort this problem out, and I strongly recommend Sublime Text 3 for that.

After trying all of the above. Simple work for me to rename package flutter with Android Studio:

Step 1:

Mac: Command + Shift + R

Linux/Windows: Ctrl + Shift + R

After change to new package and press Replace All and wait Android Studio run finish.

https://i.stack.imgur.com/Jed6C.jpg

Step 2:

Next, go to AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="your.package.name">

and copy package name and do the same Step 1 to rename package in AndroidManifest and build.gradle.

Finally, change the package in your MainActivity.java class (if the MainActivity.java is not available, check the MainActivity.kt)

package your.package.name;

import android.os.Bundle;
import io.flutter.app.FlutterActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;
public class MainActivity extends FlutterActivity {

Change the directory name. For details see the following link this:

From:

android\app\src\main\java\com\example\name

To:

android\app\src\main\java\your\new_package\name

---

EASY way, in editor search E.g.VS CODE your.package.name E.g com.example.application through all files.,

3 AndroidManifest files(profile, debug, main)

1 build.gradle

1 java or kt file

these will popup

Replace all these and voila. If you have already build your project, numerous files will popup in the build directory, you can ignore that files, no need to change those

---

As of Android Studio 4.1.3, changing package name couldn't be more easy.

If you don't use Firebase or any other external service, just change the package name in these files:

In the build.gradle (app) file In the Manifest file (main, debug and profile) Package import in code files (Android Studio. will handle the changes)

NOTE: Also change the directory name (under Kotlin or Java).

If you use Firebase or any other external Service, you need to change the package name there too.

In Android, change application id in

> build.gradle

file and iOS change

> bundle name from project settings.

---

If you don’t like changing files in such a way then alternative way would be to use this package.

https://pub.dev/packages/rename

rename --bundleId com.newpackage.appname
pub global run rename --appname "Your New App Name"

Using this, you simply run these 2 commands in your terminal and your app name and identifiers will be changed.pub global run

---

Use this plugin (2022)

https://pub.dev/packages/change_app_package_name

Usage

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

Old Package Name: com.example.oldname
Updating build.gradle File
Updating Main Manifest file
Updating Debug Manifest file
Updating Profile Manifest file
Project is using kotlin
Updating MainActivity.kt
Creating New Directory Structure
Deleting old directories

---

You can follow this official documentation by Google: https://developer.android.com/studio/build/application-id.html

Application ID should be changed in Build.gradle, while package name can be changed in AndroidManifest.xml.

However one should be careful changing package name.

Also while re uploading the app, one should be careful since it matches the application ID of previously uploaded app with new upload.

---

I don't think it's the proper solution for the problem. But you can just create a new project with the package name you want and then copy all the source files to the new project from your existing projects.

**NOTE: You'll have to copy all the contents of pubspec too. In the case of firebase and other APIs, that solution may be a bit lengthy.

---

I have done global search for existing package name, and changed all fields with new package name. Then changed

app->src->main->yourOldFolderName

folder name as per new package name. After that, changed all imported package name to new package name. It was a lot of manual work but was worth it, without any issues.

Note: Watch for the blank space before package name it may give built errors

Short-cuts:

global search- ctrl+shift+f

To change package

file search- ctrl+f

To change import package name

---

Add Change App Package Name to your pubspec.yaml in dev_dependencies: section.

dev_dependencies:

change_app_package_name: ^1.1.0

Update dependencies flutter pub get

Run this command to change the package name.

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

Where com.new.package.name is the new package name that you want for your app. replace it with any name you want.
