how to use variables in other places-CodePudding

I have a variable named "prodCol" that it is in item builder ...how can I use it in another page?

GridView.builder(
itemBuilder: (BuildContext context, index) {
 final varProd = snapshot.data![index];
final prodCol = varProd.get('colo');                                  
}
)

You can give it any other global variable and send the global variable to another page as a paramather. But I don't know whether this is useful or not.

Si quieres pasar ese dato en otra vista, mandalo como parámetro por el router. Googlea como pasar parámetros por el router y ahí encontrarás mucha informacion.
