Is there any way to change Package Name of Flutter project?

I want to change package name and application name in flutter project.

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.

Change name attribute in pubspec.yaml (line 1)

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

This is how i renamed package for both ios and android

1. Go to build.gradle in app module and rename applicationId "com.company.name"
2. Go to Manifest.xml in app/src/main and rename package="com.company.name" and android:label="App Name"
3. Go to Manifest.xml in app/src/debug and rename package="com.company.name"
4. Go to Manifest.xml in app/src/profile and rename package="com.company.name"
5. Go to app/src/main/kotlin/com/something/something/MainActivity.kt and rename package="com.company.name"
6. Go to app/src/main/kotlin/ and rename each directory so that the structure looks like app/src/main/kotlin/com/company/name/
7. 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
8. Go to each dart file in lib folder and rename the imports to the modified name.
9. Open XCode and open the runner file and click on Runner in project explorer.
10. Go to General -> double click on Bundle Identifier -> rename it to com.company.name
11. Go to Info.plist click on Bundle name -> rename it to your App Name.
12. close everything -> go to your flutter project and run this command in terminal 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

change in all AndroidManifest.xml files of your Flutter Project, --> package="your.name.app" (app/src/debug/AndroidManifest.xml) and (app/src/main/AndroidManifest.xml) and (app/src/profile/AndroidManifest.xml)

good look !!

On Visual Studio code

Edit > Replace in Files

On Android studio

1. Right click on your project > Replace in path

2. Write your old package and new package > Replace all

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

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

last step is to run flutter clean

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

Quickest and cleanest way to change your package name :

Warning : You may want to save some files in android/ and ios/ folder before it gets deleted !

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

• android/
• ios/
• build/

2. Let's say you want to rename from com.oldcompany.oldproject to com.newcompany.newproject Launch the following code :

   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 typing the commands grep --color -r com.oldcompany.oldproject * and grep --color -r com.newcompany.newproject *

I had two manifest.xml file in my app section,so I needed to change package name in both

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.

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

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

1. Get Sublime Text (crazy, right? No, just follow my steps)
2. Click on file and select open folder, then choose the folder of the project you are working on
3. 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)
4. 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.
5. Click on FIND (do not click on REPLACE just yet).
6. 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.
7. 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.

the right to change path for default way for both Android and Ios.

for Android

open AndroidManifest.xml,

• go to this path.

app/src/main/AndroidManifest.xml

• select on package name, and right click,

• after click on rename, rename popup(dialog) show.

• enter the new package name here,

• after changes name text, click on refactor button.

__________________________________________________________________________

for Ios

• select ios folder from drawer, and right click on these,

• select,and double click on Runner in drawer,and then select General

• and then, change your Bundle Identifier(Package Name).
• after changes Bundle Identifier(Package Name), Your Package Name is changed for Ios.

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

Package Link on Pub Dev

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.

In Android, change application id in

> build.gradle

file and iOS change

> bundle name from project settings.

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

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
