Is It Possible To Make One Parameter Can Accept Value/Dat from Different Function/Data Type?-CodePudding

I have two model dart. The one is PromoModel and the other one is DealsModel but the model has a similar structure (but not the same).

I only need one page (details page of promos and deals). So I thought, maybe it would be too redundant to have to create 2 detail pages, which are UI-like they are the same, and only differ from the parameters.

I see a lot of Functions or Classes that accept value/data with data type T. So is it possible to create only one class (UI/Page View) but can accept different Data types (in my case it is List PromoModel and DealsModel)?

CodePudding user response：

Yes, you can do that with dart generics

The page code will look something like this

class Page<T> extends StatelessWidget {
List<T> _pageData;
// Add other variable
// Add construtor
  @override
  Widget build(BuildContext context) {
    return Container(
     // Add stuff here
    );
  }
}

Then you can create the page like this

Page<DealsModel>();

But with this approach, depending with the structure of your model, you may need to write some conditional logic in the page to account the differences of the model structure.
