How to acces parameter value from constructor in flutter?-CodePudding

I'm having trouble with accessing the value of a parameter from a constructor in my code. I access to this page from another one where I get the value of the parameter:

final route = MaterialPageRoute(
                          builder: (context) => AnadirJugadores(idPagina: respuesta['id'],));
                      Navigator.push(context, route);

This is the code of AnadirJugadores:

class AnadirJugadores extends StatefulWidget {
    final String idPagina;
  AnadirJugadores({required this.idPagina });
  
  String cogerID() {
    return this.idPagina;
  }

  @override
  State<AnadirJugadores> createState() => _AnadirJugadoresState();
}

class _AnadirJugadoresState extends State<AnadirJugadores> {
  
  @override
  Widget build(BuildContext context) {
      
    .... more code
    ElevatedButton(
                      child: Text(idPartida), // this is the line of the error
                      onPressed: () {
                        final data = ClipboardData(text: '25342756374');
                        Clipboard.setData(data);
                      },
                    ),

I'm trying to access the value of idPagina. How could I do that? Thanks in advance.

CodePudding user response：

When using stateful widgets you need to use widget to access the parameters.

child: Text(widget.idPartida),

CodePudding user response：

In StatefulWidget your constructor exists in upper class (it's not in State class), so to access data in this constructor in your state class you should do this:

ElevatedButton(child: Text(widget.idPartida), ...),
