 The Web UI package implements the &lt;template&gt; tag,
 which you can use directly in your HTML.
 Templates define UI elements that are instantiated

 You can use templates to define the structure of a custom element,
 to instantiate UI elements based on a boolean condition,
 or to repeat UI elements by iterating over a Dart Iterable object.
 
 This target covers
 template conditionals and loops,
