StandardPageWithResultFactory<T extends StandardPageWithResult<R, E>, R extends Object?, E extends Object?> class base

A factory class for creating StandardPageWithResult instances that returns a value E. This class can be added to the pages property of StandardMaterialApp.new or StandardCupertinoApp.new. T is the Represents the data type of the destination page, R is the Represents the data type of the page data, E is the Represents the data type of the value returned by the page.

For how to pass and configure this class in StandardStatefulMixin.pages, please refer to the documentation of StandardPageFactory.

The key distinction to StandardPage is that this class returns a value. For example, a PageWithResult is a screen of type StandardPageWithResult that returns a result of type String.

example:

class PageWithResult extends StandardPageWithResult<void, String> {
  @override
  Widget buildPage(BuildContext context) {
    return Scaffold(
      body: Center(
        child: TextButton(
          onPressed: () {
            // Set the result of this StandardPageWithResult to the pageResult.
            pageResult = 'pageResult';
            Navigator.pop(context);
          },
          child: const Text('Navigator Pop Page'),
        ),
      ),
    );
  }
}

You can retrieve the result of PageWithResult as shown below, using goWithResult for navigation.

example:

final tResult = await context.goWithResult<PageWithResult, void, String>(null);
