Flutter 高仿知乎 UI，非常漂亮，也非常流畅。
使用 Flutter 模仿的知乎黑色主题的 UI。
在 “我的” 页中可以修改日间和夜间模式。
这是我当初初学时做的一个 demo ，看着代码做一遍基本可以入门 Flutter，学会 APP 布局。
照着这个 demo ，两三天做下来，一周入门不是问题。
现在我使用 Flutter 已经 5，6 个月了。我的更多 Flutter 的分享在：https://zhuanlan.zhihu.com/flutter
我是在IOS 模拟器里打开的
请问如何处理 输入法键盘遮挡的问题呢
首先感谢开源了这么好的内容,
我已经下载了项目并且在项目执行flutter run 希望看一下启动后的效果,但是很遗憾,启动失败了,日志如下:

我初步猜想是和版本有关系,不知道开发这个项目用的版本信息是多少呢?
我的flutter在今晚更新了一次,用的版本是v1.15.18
安卓机版本5.1 也许是这个版本低了,我正在尝试安装一个较新的版本
web调试，Chrome打开，通过滚轮滑动页面后，会导致点击屏幕出现蓝色透明层
如图，需要点击一次底部兰，底部栏才会切换主题。
我看了一下代码，
发现是根据index来决定加载哪个页面的
这样是不是不太好？
每次重新滑到页面的时候，这个页面都会重新加载，没有复用。
还是自己靠感觉写的?
底部BottomNavigationBar选中状态存在问题（点击选择菜单切换到应用外在切回来时出现截图中问题：选中的灰色底纹一直存在。）。
请问你有没有遇到这样问题，有什么解决方法吗？
官方的demo我本地可以热加载,但是你这个不行
亲，有没有遇到win10设置的镜像用不了的情况呢？一直卡在这Waiting for another flutter command to release the startup lock...
解决了：Execution failed for task ':app:processDebugResources'.问题 启动失败 后遇到的新问题
主要：
faild：app:transformClassesWithDesugarForDebug
更多：
Running Gradle task 'assembleDebug'...
注: 某些输入文件使用或覆盖了已过时的 API。
注: 有关详细信息, 请使用 -Xlint:deprecation 重新编译。
