Working with the Angular tree

Lewis Cianci I'm a passionate mobile-first developer, and I've been making apps with Flutter since it first released. I also use ASP.NET 5 for web. Given the chance, I'll talk to you for far too long about why I love Flutter so much.

  1. treeControl is deprecated, use one of `levelAccessor` or `childrenAccessor` instead. To be removed in a future version.

  2. The flat tree has performance benefits. Your example was just not suited for it . Ideally you want to render the entire tree at once, and not load it every time you expand a node. But wait, if you use a nested tree and give the entire tree at once, you can have performance issues. That is the point of the flat tree. Where nested tree struggles, flat tree comes to the rescue. It’s easier for the DOM to render one level when the number of elements is high.
