android - Flutter可重用表单小部件

Question

我已经使用方法addTicket()实现了类，当我重用该类时，我想根据应用程序中的相关页面更改“db.collection”的名称和“Navigator”。那该怎么办呢？

class AddNewTicket extends StatefulWidget {  
  @override
  _AddNewTicketState createState() => _AddNewTicketState();
}


class _AddNewTicketState extends State<AddNewTicket> {

  addTicket() async {
    if (_formKey.currentState.validate()) {
      _formKey.currentState.save();
      try{
        DocumentReference ref = await db.collection('CostalLineTicketDetails').
        document(ticketCato).collection("Tickets").add();
        setState(() => id = ref.documentID);
        Navigator.push(context, new MaterialPageRoute(builder: (context) => CostalLine()));
      }catch(e){
        print(e);
      }
    }
  }
}

您可以执行以下操作:

  addTicket(String collectionName, Widget widgetPage) async {
    if (_formKey.currentState.validate()) {
      _formKey.currentState.save();
      try{
        DocumentReference ref = await db.collection(collectionName).
        document(ticketCato).collection("Tickets").add();
        setState(() => id = ref.documentID);
        Navigator.push(context, new MaterialPageRoute(builder: (context) => widgetPage));
      }catch(e){
        print(e);
      }
    }
  }
