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

A factory class for creating child pages of StandardPageWithResult.

This class can be added to the childPageFactories property of StandardPageWithResultFactory or StandardPageFactory. T represents the data type of the destination page, R represents the data type of the page data, E represents the data type of the value returned by the page, P represents the data type of the parent page data.

Child pages are designed to have a parent-child relationship with their parent page. The createParentPageData function is required to generate the parent page data from the child page data, which is used when navigating through the page hierarchy and building deep links.

When navigating to a child page using the go method, you can set the pushParentPage parameter to true to automatically push the parent page onto the navigation stack before navigating to the child page. This ensures that the parent page is included in the navigation history.

example:

StandardMaterialApp(
  onGenerateTitle: (context) => 'sample',
  pages: [
    StandardPageFactory<TestPageA, void>(
      create: (data) => TestPageA(),
      links: {
        r'pageA': (match, uri) {},
      },
      linkGenerator: (pageData) => 'pageA',
