Flutter change app name and icon

 

 Changing the App Launcher Name

By default, when a flutter app gets installed, the app name on the launcher is your Flutter project name. To change that to your desired application name on Android or iOS both, you need to change AndroidManifest.xml and Info.plist respectively.

For Android

Inside, find <application>and change its android:label property with your desired app name.

android/app/src/main/AndroidManifest.xml

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="your_app_name"
        android:icon="@mipmap/ic_launcher">

iOS

ios/Runner/Info.plist

<key>CFBundleName</key>
<string>your_app_name</string>

That’s it. By having these changes, we’ll get an updated application name in launcher when our app gets installed on a device.

Change the icon manually

If the tools above doesn't work for you or maybe you need more customization, you can set the launcher icon manually.

For Android, go to android/app/src/main/res folder. You should see some folders beginning with mipmap-* which represent different pixel densities. Replace launcher_icon.png file in each folders to use custom icons.

For iOS, the icon config and files are located inside ios/Runner/Assets.xcassets/AppIcon.appiconset. The Contents.json file defines a list of icon images with different sizes and scales. The files are located in the same folder. It's recommended to follow the guideline for designing iOS icon.
