flutter create xxapp后，打开运行工程，报错如下：
Flutter: Runner.app/Info.plist does not exist. The Flutter “Thin Binary” build phase must run after “Copy Bundle Resources”，
解决方法：
打开 Runner -> Build Phases -> Thin Binary, 如下图所示：
将图中的脚本更改如下：
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build.
重新Build一下就可以了。
