请问这个支持筛选的多选功能吗

为什么我的小米max3特别的卡顿？完全没有rn 流畅？

请问下这里为什么要用Offstage包裹一下， offstage =true 不是吧控件隐藏了吗？

还有这里

NestedScrollview为什么还要 在添加一次 顶部的布局v

拉取代码后，提示dart sdk版本>=2.1.0<3.0.0 才行，我在vscode运行失败了，是需要 flutter工具包的版本在 >=2.1.0<3.0.0 范围吗？？

请教一下大佬给方法添加注释用的什么插件？还是纯手敲？
像这个：

最好能支持m3u8,直播等功能的插件推荐?
谢谢

我直接用vscode flutter run行吗，大神指点下谢谢

但是桌面面播放器出不来，你有试过播放器windows上能跑得起来吗？

不知道是我个人原因还是大家都这样，其他项目没问题但是这个项目package get的时候毫无进度，有没有其他同学get成功的？

楼主真厉害，项目功能很完整，但是在做的时候遇到点问题，望楼主帮忙看一下（楼主的项目也会出现）。就是在用appbar+FlexibleSpaceBar+tabbar+tabbarview显示首页的内容的时候，如果FlexibleSpaceBar的内容比较多，页面向上滑动的时候，还没到显示tabbar，但是这时候商品列表已经开始滑动了，等到滑动到tabbar的时候，商品列表显示的已经不是第一个item了。楼主可以尝试加多FlexibleSpaceBar的内容就会出现这种情况，尤其是一开始先快速滑动，后面再慢慢滑动到tabbar，情况更明显

遇到一个非常奇怪的问题，我在HomePage的build方法中返回自己的一个UI布局，在布局中有个点击事件，跳转到下一个页面。过程：进入首页，点击首页中的按钮跳转到下一个页面，再返回到首页，这时候切换底部导航栏的另外一个tab，再返回来，HomePage就丢失了状态（重新执行了initState方法）。其它的地方全都没改动，只是在HomePage中返回自定义的UI布局，而楼主的自己的UI布局是没有这个问题的，请问一下楼主在这个HomePage的状态保持是不是有特殊的处理？或者对于这个问题有没有什么处理办法？

我猜测是不是图片加载过多，内存暴涨了，滚动掉帧；高配手机上又相对好点；

如题

等着老哥 代码开源

1. 建议版本目前不要支持androidx, 还是跟这个稳定版走比较好, flutter_statusbarcolor编译失败, 用0.1.4版本就很妙了
2. 建议原始仓库只放代码就可以了, android什么证书乱遭的就不要放了
3. 顺便问下作者, 状态管理用的是啥?

请问一下签名文件没找到key/key.jks，在哪里可以下载呢

有两个问题一直百思不得其解，请教一下作者，
1，offstage的属性为true，就是影藏了，相当于没有，但是我将Offstage这个widget删除后，就溢出了，部分内容无法显示，
2，GZXTopBar放在column里面，如何做到固定在在顶部的呢，

1.2.0版本以上的，建议注释掉 defaultConfig 里面的ndk；

好像是因为cpu架构不支持。然后想安装你自己打的apk，但下载链接又出问题。所以还没有真机看过是什么样子的。

一左滑关闭，就崩溃了

首页 body TabView内容显示问题
例如：点击第三个tab，第二个TabView的内容会显示为第一个TabView的内容
