Steps to reproduce

The issue only happened on iOS devices.

2. Calling Permission.notification.status or Permission.notification.request() both return Denied. The result is shown in the screenshot below.

Expected results

Must be "Granted" status if the permission was allowed.

Actual results

Always returns Denied.

This issue can also occur if you don’t add the notification permission flag in your Podfile. It might be worth checking if you have the following configuration inside the post_install block:

config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
  '$(inherited)',

  ## dart: PermissionGroup.notification
  'PERMISSION_NOTIFICATIONS=1',
]

Without this, the iOS permission status will always return Denied.

[mohsinelahii]

config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [ '$(inherited)',

dart: PermissionGroup.notification

'PERMISSION_NOTIFICATIONS=1', ]

Thank you, it worked.
