# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

the most common usage,
child wrap ListView,GridView,CustomView,Widget,
RefreshConfiguration is a global setting,just like theme,All refreshers under the RefreshConfiguration subtree will refer to its properties,
in this example,I gave RefreshConfiguration a property headerBuilder,The default header indicator for the four refreshers is it.
If you use almost the same page indicator, using Refresh Configuration can greatly reduce the complexity of your work.

/*
this example will show you how to hide Footer by the sizeOfContent,
SmartRefresher has an ability to automatically hide indicators when less than one page,e
when your slivers have some complex sliver,which will cause error hiding,so You need to hide it yourself.
though many widgets provided by flutter doesn't have this situation
first step: give RefreshConfiguration's hideFooterWhenNotFull = false
second step: use LayoutBuilder get the Widget height
third step: Use your judgment to decide whether to hide footer, enablePullUp = false

实现聊天列表+加载更多功能,类似于qq那种加载效果
聊天列表最大的难点就是在列表不满一屏时,要把它往上压。目前来说,flutter没有提供这类sliver能把剩余空间(上和下)给占有,类似于Expanded,
SliverFillRemaing并没有起作用。
ExpandedViewport是我自定义Viewport,用来解决当不满一屏时reverseListView要居于顶部的问题(只适用于少数情况),原理就是第一次
布局先探测一下他们的布局情况,第二次布局假如不满一屏,就在SliverExpanded后面的所有slivers调整主轴偏距。

# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.io/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.io/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700

# For details regarding fonts from package dependencies,
