Fragment
Renders multiple components where only one is accepted.
Fragment is a basic utility component that renders its children without any wrapper element.
Fragment(children: [
h1([text("Welcome")]),
p([text("Hello World")]),
]),
This is meant to be used in places where you want to render multiple components,
but only a single component is allowed by the API.
For example a custom builder method that only allows returning a single Component, like Route.builder.
