You are running `flutter run` and you are having this problem.

You might have updated the **Display Name** from `Runner` to `your app name`

To make it work, we need to update the **Display Name** to `Runner` back (General tab).

```
Xcode -> Runner -> Runner (under Targets) -> General -> Display Name (Under Identity)
```

> **Note: Changing this will not effect your app’s display name.**
