String 字符串

在哪里存储字符串? 如何存储不同的语言 目前,最好的做法是创建一个名为Strings的类 class Strings{ static String welcomeMessage = "Welcome To Flutter"; } 然后在你的代码中,你可以像访问你的字符串一样:new Text(Strings.welcomeMessage)

Json序列化

生成序列化模板 flutter packages pub run build_runner build --delete-conflicting-outputs

配合AutomaticKeepAliveClientMixin可以keep住tab

如何主动刷新refresh,如何设置appbar上的leading和bottom,如何设置tabbar的live

//升级到0.5.7 对三个以上tab还是有问题,TabBarView放弃,使用PageView,实现两个control同步,GlobalKey也没问题了。 flutter/flutter#19809 flutter/flutter#11895 tab alive _debugUltimatePreviousSiblingOf GlobalKey可以记录state,但是需要跟随build创建 https://stackoverflow.com/questions/49862572

if you use AutomaticKeepAliveClientMixin to keep alive page item,you can't write like this:

PageView(
controller: _pageController,
onPageChanged: (index) {
onPageChanged(index);
},
children: [NewsList(),Text('page1'),Text('page2'),Text('page3')],
),

you should write like this:

List _list = [
NewsList(),
Text('page1'),
Text('page2'),
Text('page3')
];
PageView(
controller: _pageController,
onPageChanged: (index) {
onPageChanged(index);
},
children:_list,
), 

webView

flutter/flutter#19030 没有webview,残念 fluttercommunity/flutter_webview_plugin#23 flutter/flutter#730

兼容性

flutter 的跨平台见兼容性意外的话,得益于flutter engine,skia的渲染,只需要canvas 所以第一次运行意外的没有兼容问题,特别是有生之年在ios上看到完全一模一样的下拉刷新

dialog上黄色线

https://stackoverflow.com/questions/47114639/yellow-lines-under-text-widgets-in-flutter Dialog中,没使用Scaffold ,导致文本有黄色溢出线提示,可以使用Material ,color或者type为透明

热更新

hotload很有优势。

热更新的新包如果包含了原生代码,需要停止后重新运行哦。

动画、本地通讯

upgrade 和 get的区别,在于lock 在yaml线下,^代表大于等于哦

redux 下切换主题

谷歌推荐redux

///ios编译失败 flutter/flutter#19241 (comment)

flutter/flutter#18305

open ios/Runner.xcodeproj
I checked Runner/Pods is empty in Xcode sidebar.
drop Pods/Pods.xcodeproj into Runner/Pods.
"Valid architectures" to only "arm64" (I removed armv7 armv7s) #13364 

你需要选flutter build ios 之后它会修改你的Podfile.lock文件指向
