I just made a Flutter app following the instructions of this page, and I googled how to change the name of the application, and found this answer. But I can't change the name of the application from the manifest file. Initially android:name is io.flutter.app.FlutterApplication. I changed that to Startup Namer, and it gave the error

error: attribute 'android:name' in <application> tag must be a valid Java class name.

How to reslove this error and change the name?

    I tried it now, it still gave the same error. However, I saw another parameter android:label and changed it to Startup Namer, and it worked. Commented Sep 23, 2018 at 15:18

The displayed name of the application is identified by the attribute android:label. You should change that one instead of android:name.

Edit AndroidManifest.xml for Android and info.plist for iOS

For Android, edit only android:label value in the application tag in file AndroidManifest.xml located in the folder: android/app/src/main

Code:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"> <application android:name="io.flutter.app.FlutterApplication" android:label="Your Application Name" //here android:icon="@mipmap/ic_launcher"> <activity> <!-- --> </activity> </application> </manifest>

For iOS, edit only the value inside the String tag in file Info.plist located in the folder ios/Runner .

Code:

<plist version="1.0"> <dict> <key>CFBundleName</key> <string>Your Application Name </string> //here </dict> </plist>

Do a flutter clean and restart your application if you have a problem.

In addition to this, for iOS I also needed to update CFBundleDisplayName
