FCM Http v1

[Megatronicus]

I received an email to upgrade fcm to http v1 however the official example for flutterfire firebase messaging still doesn't have http v1 implemented. The regular fcm http service stops support in June 2024. It would be great to have the new example for flutter http v1 so I can migrate the app without having to do it in the last minute. I found 1 single example on github and it's not official and is missing a lot of code to get the vapid key for example and some other things. Why are you sending out emails for the upgrade if there is no official code yet for the upgrade. Not only have I received emails, there is an official page https://firebase.google.com/docs/cloud-messaging/migrate-v1 with very obscure instructions and no definitive example. Can we please get an example how to do http v1 in flutter?
