Adding new roles in the same application - flutter

Question

Im trying to add a new sign in role for Rider to sign in to see the orders from customers in the same app but im not sure if im able to add it into my existing code for currently just user to register, sign in and sign up for a new role which is the rider. Would appreciate some advice or suggestion. thank you.
my user model:
class UserModel {
String? uid;
String? email;
String? firstName;
String? secondName;
UserModel({this.uid, this.email, this.firstName, this.secondName});
// receiving data from server
factory UserModel.fromMap(map) {
return UserModel(
uid: map['uid'],
email: map['email'],
firstName: map['firstName'],
secondName: map['secondName'],
);
}
// sending data to our server
Map<String, dynamic> toMap() {
return {
'uid': uid,
'email': email,
'firstName': firstName,
'secondName': secondName,
};
}
}
my sign up:
