Facebook Log In flutter, get user ID

I'm trying to get the facebook friends of my new users (to recommend them friends). I did all the work: integrated facebook in the app, permission facebook etc.

Then I use this to get the users

curl -i -X GET \
 "https://graph.facebook.com/v4.0/ i put the user id here }?fields=id%2Cfriends&access_token= my acces token"

It works, but there's a problem with the id's:

If i use the facebook graph API: it says my ID is : 23337 ... (only digits).

If i log in with facebook in the flutter app: my ID is: M670V ... (digits + (capital) letters )

Only the id with only digits works for the curl. How can I get the id with only digits from the flutter facebook sing in?

Thank you!

Solution

  • After a bit of research,

    The id with digits + letters is the firebase ID, it differs from the real facebook id.

    Thanks for the help!
