White screen when trying to integrate the flutter with the firebase message ios

[Giuliano Saito]

I am trying to integrate the firebase message into my flutter application. On Android it works perfectly, but in Ios, when building the application, it opens a white screen and nothing else appears.

I was able to run the app successfully only once, where a request appeared to receive push messages from the firebase, even until I was able to send a notification.

I uninstalled the app and tried to install again, after that it only stays on a white screen and Ios no longer issues the notification requesting permission to send push.

In X-code Capabilities, I enabled Push Notifications and in Background modes "Background fetch" and "remote notifications"

Has anyone ever experienced this?
