Find an iOS bundle identifier in the flutter application

Question

I am working on a flutter app and cannot find the bundle identifier. According to the documentation here (https://firebase.google.com/docs/flutter/setup), it should be in the General tab but I can't find it. I've also read in places that it could be here: ios/Runner.xcodeproj but my project doesn't contain that. Thanks!

Answer 1

Easiest way to find it is doing the following:

• Open your Flutter Project on Android Studio or VS Code
• Search PRODUCT_BUNDLE_IDENTIFIER =
• Hit Enter, open the file and check your Bundle Identifier

There's other way to do it but you need MacOS with XCode installed:

• With Finder got to your Flutter folder, then iOS and open Runner.xcworkspace (white icon)
• Double click and open it on XCode.
• Upper left corner (Project Navigation), click on Runner
• Over Identity you'll have several fields, one of those is Bundle Identifier

Answer 2

For Bundle ID and Package Name changes,

For IOS:

1. Look for file

project/ios/Runner.xcodeproj/Info.plist

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

<key>CFBundleName</key>
<string>notification</string>

2. To change the value, look for file

project/ios/Runner.xcodeproj/project.pbxproj

PRODUCT_BUNDLE_IDENTIFIER = com.sara.fcm.notification;

3. flutter clean

For Android (4 places):

1. AndroidManifest.xml

android/app/src/main/AndroidManifest.xml
android/app/src/debug/AndroidManifest.xml
android/app/src/profile/AndroidManifest.xml

2. android/app/build.gradle

   defaultConfig {
      applicationId "com.sara.fcm.notification"
    ....
   }
   

3. (kotlin or java) android/app/src/main/kotlin/com/../MainActivity.kt

package com.sara.fcm.notification
import io.flutter.embedding.android.FlutterActivity
class MainActivity: FlutterActivity() {}

4. Refactor the directory name(MainActivity) and flutter clean

Answer 3

Here is the simplest way:

It's the value inside the String tag in file Info.plist located in the folder ios/Runner .

Bundle ID will be here : <string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>

You can modify it
