ListDataBuilder<T> class sealed

A sealed class that defines how a list of data should be displayed.

It contains two subclasses: ListDataBuilderString and ListDataBuilderCustom.

ListDataBuilderString is used to display a list of data as strings. It takes a labelBuilder which is a function that takes a data and returns a string label for the data.

ListDataBuilderCustom is used to display a list of data as custom widgets. It takes a builder which is a function that takes a build context, a data, and a ListTileMetadata object, and returns a widget for the data.
