Collection constructor
The default constructor for creating a Collection with a static list of child widgets.
This constructor initializes the widget for rendering a fixed set of Widget children. It sets
the builder-related fields to null and disables custom builder mode, making it suitable for
simple, non-dynamic lists. The children parameter accepts a list of widgets that will be
rendered, defaulting to an empty list if not provided.
Example:
Collection(children: [
Text('Item 1'),
Text('Item 2'),
])
Implementation
const Collection({super.key, this.children = const []})
: childCount = null,
builder = null,
customBuilder = false;
