iOS项目集成Flutter

1. 在Android Studio创建的Flutter项目时不要选择Flutter Application，应该创建最后一个Flutter Module

2. 将Flutter项目和iOS项目放到同一级目录下（方便原生引用Flutter项目）

3. iOS原生项目通过CocoaPods引入Flutter

platform :ios, '9.0'
use_frameworks!
target 'NavtiveDemo' do
  flutter_application_path = '../flutter_module_demo/'
  eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)
end

4. Xcode的Enable Bitcode设置为NO
5. 添加编译脚本，在Xcode的Build Phases中添加New Run Script Phase在里面填入如下脚本，并且将Run Script移动到第二项

"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
