### Please check the following before submitting a new issue.

- [X] I have searched the [existing issues](https://github.com/baseflow/flutter-permission-handler/issues).
- [X] I have carefully [read the documentation](https://github.com/Baseflow/flutter-permission-handler/blob/main/permission_handler/README.md) and verified I have added the required platform specific configuration.

### Please select affected platform(s)

- [X] Android
- [ ] iOS
- [ ] Windows

### Steps to reproduce

1. Use a callback `Permission.contacts.onGrantedCallback`
2. Grant permission for camera.
3. `Permission.contacts.onGrantedCallback` will be invoked.

### Expected results

When using `Permission.contacts.onGrantedCallback` we expect this callback to invoke only if we grant permission for contacts.

### Actual results

No mater what permission you add callback it will always gets invoked for every permission.

### Code sample

Code sample

```dart
Permission.contacts.onGrantedCallback(
() {
print('Contacts permission granted.');
},
);
```
