You do not have to change the package name in Firebase and you can change the package/application name as per your needs.
***1. For changing the app name:***
Change the label name in your AndroidManifest.xml file:
<application
android:name="io.flutter.app.FlutterApplication"
android:label="TheNameOfYourApp"
***2. For Package Name***
Change the package name in your AndroidManifest.xml 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
**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` 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
```
