Flutter default adds the project name as an application display name. But maybe we need a different name for the display than the project name.
There is no straightforward way to change the display name from a single place. We have to edit the android config and iOS config separately. But it just a two-line
Go to android→ app → src → main and open the AndroidManifest.xml file. In there under the application tag, there is a android:label attribute. Set the application name which you need to display for that value
Go to iOS → Runner and open Info.plist file. There you can see <key>CFBundleName</key> and value would be your application name. Set the name you need for that string tag.
<key>CFBundleName</key> <string>Food App </string>
Next, open the terminal and run the following command.
Now run the app in both iOS and Android devices to see the new app name.
