过程问题：

1、BottomNavigationBar 超过4个底部控制颜色变白：https://www.jianshu.com/p/946f1e476ca5

2、shrinkWrap 解决gridview不能在customScrollView显示的问题

4、

因误操作user方法又返回了user对象导致报了下面的错误，定位了好久

User get user {
    if (_user != null) {
      return user;
    }
    _user =  User.fromJson(SpUtil.getObject("pp_user"));
    return _user;
  }

5、网络请求增加mock功能

6、保存相册 报Swift问题 ，增加use_frameworks!即可

7、InkWell 下面的Container设置color会导致水波纹无效

8、android studio GradleException报错 死命的更新就行了

9、NestedScrollView导致其body的tabbarview的多个list同步滚动的解决方案 https://www.jianshu.com/p/ab473fb8ceb0

10、Listview addRepaintBoundaryies RepaintBoundary

11、context.dependOnInheritedWidgetOfExactType :InnerWidget数据变化会导致使用者也跟着变 和 context.getElementForInheritedWidgetOfExactType().widget则不会

12、package版本冲突使用

dependencies:
  some_package:
  other_package:
dependency_overrides:
  url_launcher: '0.4.3'

android

configurations.all {
    resolutionStrategy {
        force 'com.google.guava:guava:23.0-android'
    }
}

13、别忘了修改packages/flutter_tools_gradle/flutter.gradle里面的配置

14、打包Android时，设置多个ndk后会包下面的错误

                                                                       
* What went wrong:

15、

做双击退出的时候调用Navigator.pop(context)会出现黑屏，需要调用SystemNavigator.pop()才能完全退出。

16、hero组件在tab下多次使用造成重复，建议少用
