FetchAndSubmitPage<F> class

A page that combines data fetching and form submission capabilities.

This page will:

  • Automatically fetch data on initialization using dataFetcher
  • Display a loading indicator while fetching
  • Show error state if fetch fails
  • Allow manual refresh (pull-to-refresh and refresh button on Windows)
  • Handle form submissions with loading state
  • Maintain static content during loading states if staticChildBuilder is provided

Example:

FetchAndSubmitPage<UserData>(
  pageTitle: Text('User Profile'),
  dataFetcher: () => getUserData(),
  builder: (data, context) => UserForm(data: data),
  staticChildBuilder: (child, context) => Column(children: [Banner(), child]),
)
