5/// The Flutter rendering tree.
6///
7/// To use, import `package:flutter/rendering.dart`.
8///
9/// The [RenderObject] hierarchy is used by the Flutter Widgets library to
10/// implement its layout and painting back-end. Generally, while you may use
11/// custom [RenderBox] classes for specific effects in your applications, most
12/// of the time your only interaction with the [RenderObject] hierarchy will be
13/// in debugging layout issues.
14///
15/// If you are developing your own library or application directly on top of the
16/// rendering library, then you will want to have a binding (see [BindingBase]).
17/// You can use [RenderingFlutterBinding], or you can create your own binding.
18/// If you create your own binding, it needs to import at least
19/// [ServicesBinding], [GestureBinding], [SchedulerBinding], [PaintingBinding],
20/// and [RendererBinding]. The rendering library does not automatically create a
21/// binding, but relies on one being initialized with those features.
