[!] CocoaPods could not find compatible versions for pod "simple_rsa":

Specs satisfying the `simple_rsa (from `.symlinks/plugins/simple_rsa/ios`)` 

解决方案：

在iOS目录下的Podfile文件中添加一行config.build_settings['SWIFT_VERSION'] = '4.0',添加后是这样

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings['SWIFT_VERSION'] = '4.0'
    end
  end
end

• 用fluro跳转页面后，页面黑屏了，其他页面显示正常
  原因：跳转后的页面不是Scaffold，用Scaffold包裹了一下好了，上个页面也是Scaffold,具体原理还不清楚，处于初学阶段

• flutter.framework:Permission denied
  这是flutter的坑，从1.9+版本升级到1.10版本就可以解决

• 记一个低级错误吧，在运行过程中总是崩溃，lost connect to device ,我是用的模拟器，网上的博客和flutter在github上的issue都是说在终端输入brew upgrade --fetch-HEAD usbmuxd就可以解决，不过我的还不行，最后直接用xcode运行程序，发现是没有在info.plist中填写相册权限

• mac真机时报错 无法验证开发者

解决办法：如果是无法打开idevice_id，先在终端执行sudo spctl --master-disable,然后执行

sudo xattr -r -d com.apple.quarantine 【flutter解压后的目录】/flutter/bin/cache/artifacts/libimobiledevice/idevice_id
sudo xattr -r -d com.apple.quarantine 【flutter解压后的目录】/flutter/bin/cache/artifacts/libimobiledevice/idevicename
sudo xattr -r -d com.apple.quarantine 【flutter解压后的目录】/flutter/bin/cache/artifacts/libimobiledevice/idevicescreenshot
sudo xattr -r -d com.apple.quarantine 【flutter解压后的目录】/flutter/bin/cache/artifacts/libimobiledevice/idevicesyslog
sudo xattr -r -d com.apple.quarantine 【flutter解压后的目录】/flutter/bin/cache/artifacts/libimobiledevice/ideviceinfo

将其中【flutter解压后的目录】替换为flutter真实目录

如果是无法打开iproxy，也是按照上述办法，目录需要改变一下，在bin/cache/artifacts/usbmuxd目录下
