Update displayName while signup Firebase Flutter

I want the app to save the displayName while user signing up

I've tried: 

  Future<void> signUp() async {
    try {
      FirebaseUser user = (await FirebaseAuth.instance
              .createUserWithEmailAndPassword(
                  email: email.text, password: password.text))
          .user;
      UserUpdateInfo userUpdateInfo = new UserUpdateInfo();
      userUpdateInfo.displayName = name.text;
      await user.reload();
      showInSnackBar("User name ${user.displayName}");

      try {
        await user.sendEmailVerification();
        showInSnackBar("Email verification sent");
      } catch (e) {
        print(e);
      }
    } catch (e) {
      String errorCode = e.code;
      print(e);
      if (errorCode == "ERROR_EMAIL_ALREADY_IN_USE") {
        showInSnackBar("This email is already in use");
      } else {
        showInSnackBar("Somthing went wrong! Try again later");
      }
    }
  }

with this method, SnakBar returns a null for displayName

Setting userUpdateInfo.displayName = name.text isn't enough to actually change the name on the user account. You have to call updateProfile() and pass it that UserUpdateInfo object in order to actually change the account.

await user.updateProfile(userUpdateInfo)
