-A new Flutter project.
+## 组件
 
-## Getting Started
+深层次理解 Flutter 的 Widget，了解各个模型、渲染原理，不要再出现宽高超长但一脸懵逼的情况
 
-For help getting started with Flutter, view our online
-[documentation](https://flutter.io/).
+## 布局
+
+布局组件看似简单，但在实际操作中如不熟悉的概念的话，很容易遇到阻碍，需要熟悉各个布局的知识点、使用场景
+
+### [可滚动的 Widget](https://flutterchina.club/widgets/scrolling/)
+
+## 路由
+
+实现路由跳转有几种方式、优劣，想象下使用场景。现在路由切换时的渲染处理是否有问题？怎么提升性能
