flutter_app's Issues

大佬，登录服务挂了？登不上

大佬，应用跑起来感觉很卡

无意冒犯，确实是个优秀项目，但为什么总感觉很卡呢。。。

老哥有兴趣搞个书籍翻页的仿真效果吗

如题

fluttery_xxx 插件找不到了

能沉浸式吗？

上面一条黑黑的半透明的是什么鬼？

Hi,
When I run flutter run I get this error

Do you have any idea how to fix this?
I tried

flutter clean
rm ios/Podfile
build from Xcode
but the result was same.

ios跑不起来，准备奋战一下，作者有什么指导意见吗？

接触flutter一周，对客户端开发比较熟悉但不精通。准备拿兄台的工程跑在IOS上看看，但运行不起来，可否有些许的指导？

有打算升级到flutter 2.0吗？

multi_image_picker/multi_image_picker-Swift.h' file not found

这个问题怎么处理

打不开

Error on line 2, column 34: Mapping values are not allowed here. Did you miss a colon earlier?

解决办法：

修改：本地Flutter SDK安装路径下找到

flutter/packages/flutter_tools/gradle/resolve_dependencies.gradle

flutter/packages/flutter_tools/gradle/aar_init_script.gradle

flutter/packages/flutter_tools/gradle/flutter.gradle

3个文件中的 https://storage.googleapis.com/download.flutter.io 替换为：http://download.flutter.io
然后重新编译就解决了

2.0你这里面并没有空安全那些东西啊

请将common_utils&flustars库相关工具类源码删除，谢谢！

Flutter之AndroidX兼容问题

你好, 请教一个瀑布流相关的东西

看到项目中使用了瀑布流插件flutter_staggered_grid_view: ^0.2.7

我最近也用到了这个插件, 想问一下如果是如下图所示该如何布局?
是将整个首页放在一个listView里面还是怎么做的? 还请作者点拨一下.

在example中好多都无法获取到数据了

接口不通！

The current Dart SDK version is 2.2.1-dev.4.0.flutter-None.

Because flutter_app depends on keyboard_actions >=2.1.0 which requires SDK version >=2.3.0-dev.0.5.flutter-a1668566e5 <3.0.0, version solving failed.

Flutter2.0无法在IOS运行

您好，

我尝试了Clone Flutter 2.0+ 分支到我的Mac. 可是一直无法运行。一直报错，请问可以如何解决？

AutomaticKeepAliveClientMixin 警告问题

Flutter切换tab后保留tab状态概述 Flutter中为了节约内存不会保存widget的状态,widget都是临时变量。当我们使用TabBar,TabBarView是我们就会发现,切换tab，initState又会被调用一次。

怎么为了让tab一直保存在内存中，不被销毁？

添加AutomaticKeepAliveClientMixin，并设置为true,并且在build里必须添加super.build(context);

@override 
Widget build(BuildContext context){
super.build(context);//必须添加
}

这样就能一直保持当前不被initState了。

官方解释

A mixin with convenience methods for clients of [AutomaticKeepAlive]. Used with [State] subclasses.
Subclasses must implement [wantKeepAlive],and their [build] methods must call 'super build'(there turn value will always return null.and should be ignored).
