SearchBase class Null safety
The SearchBase class holds the state for all the active SearchController and can be used to provide the global configuration to the registered SearchController.
It serves the following tasks:
- To
register
a SearchController by uniqueid
- To
unregister
a SearchController byid
- To retrieve the instance of the SearchController class by
id
- To provide an ability to watch registered widget reactively with the help of the
react
property.
Note:
- The
id
property is a unique identifier to each search widget. - The SearchBase class is useful when you're using multiple search widgets that depend on each other. For example, a filter widget (to display the category options) depends on the search query (search widget). If you're only using a single widget then SearchController class should work well.

String, String> ? headers})
