与老版本不同的是，这么增加完引用之后，不需要自己配置Shell与设置bitcode
{
我的环境，
Xcode11.5
flutterSDK 1.17
}
官方引用更改为
platform :ios, '9.0'
target 'f_huafer' do
flutter_application_path = '../h_flutter'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
install_all_flutter_pods(flutter_application_path)
end
