majascan dependency ... required a higher minimum deployment target.

执行Flutter build ios时，如果.ios中的项目没有执行过pod install，它会先执行pod install，然后再去执行Xcode build;

Running pod install... Running Xcode build...

如果flutter项目中的一些三方插件指定了较高版本的iOS（iOS Deployment Target），会在pod install时报错：

Specs satisfying the `majascan (from `Flutter/.symlinks/majascan/ios`), majascan` dependency were found, but they required a higher minimum deployment target.

我们只需要在.ios的项目中的Podfile中将platform :ios, '8.0' 改成 platform :ios, '10.0'，大于8.0即可～
