打开app后出现的第一页动态和推荐两个tab，第一次切换的时候略有卡顿，不知如何解决，望大佬分析一波

项目导入idea报错，是flutter版本问题吗

十几mb影响clone速度，代码拉了很久

一个字：卡

如题

小白刚刚开始学习，我这个报错是因为sdk版本(1.5.4-hotfix.2)有问题么？怎么解决啊？ @kaina404

Readme 第一行，错别字

学习中 期待后续

项目down下来，就报错，这是怎么回事

大佬 是否想过出个视频教程， 我基础差 关于上拉抽屉 看你代码 没看太懂 太多了。。

为啥要这要做，可以直接删掉吗？

可能是我不会操作
运行 flutter run 提示如下

自从运行FlutterDouBan电脑发热没停过。运行其他开源项目没出现这种情况
怎么回事？

请问home_app_bar.dart是用了什么模板吗？

会不会和系统是 10.15有关

可拓展性很差，每个字段都要手动解析，有点无法接受。期待更加方便的处理方式

现在clone 和download 都不下来项目，我试了好几次都不行，很多同事都是这样，不同网络状态下都不行，大神块看一下吧！

书影音，tabView嵌入的customScrollView 滚动相互影响， 电影tab内容滚动和综艺滚动，两个其中一个滚动另一个也会随之滚动

然后我就不会搞了

小米Note手机，安卓7.0
和原生豆瓣相比，性能明显差很多，Flutter非常卡。我在开发者模式打开gpu监控，发现滑动listview时gpu不调用，原生的会调用。
我自己做的小demo百姓生活+和微信小程序相比也有性能差距。。。
这种性能非常担忧啊，体验差距明显。

这个错误结果谷歌了半天，答案全是讲解的在 build.gradle 中添加以下代码，但并非针对 flutter 的，操作了也是无效
packagingOptions { exclude 'META-INF/proguard/androidx-annotations.pro' }

能学很多东西 谢谢诶

啥时候出个视频教程

安卓 flutter run 报错

下拉刷新效果可以忽略主要是上下联动，iOS可以用scrollview的contentinset实现

视频播放全屏有什么解决方案吗？

/bin/sh: /packages/flutter_tools/bin/xcode_backend.sh: No such file or directory

设计图怎么搞的？

没看懂
