Straight forward way of declaring flutter modules as dependency for targets, just like cocoapods does with pods.

$ [sudo] gem install cocoapods-embed-flutter

gem 'cocoapods-embed-flutter'

In your host project Podfile, write the below line before any target definition

plugin 'cocoapods-embed-flutter'

pub 'flutter_module', :path => '../'

:path can be path pointing to pubspec.yaml or to the directory containing pubspec.yaml or to the directory containg flutter module.

pub 'flutter_module', :git => 'https://github.com/gowalla/flutter_module.git', :branch => 'dev'
pub 'flutter_module', :git => 'https://github.com/gowalla/flutter_module.git', :tag => '0.7.0'
pub 'flutter_module', :git => 'https://github.com/gowalla/flutter_module.git', :commit => '082f8319af'

flutter module project should be at the root of repository, if that's not the case add additional :path attribute for relative path to flutter project in repository. :path follows these restictions.

pub 'flutter_module', :git => 'https://github.com/gowalla/flutter_module.git', :tag => '0.7.0', :path => 'relative path/to/project'

• Modules hosted in pub.dev are not supported, only local modules and modules in remote sources like git are supported.
• You won't be able to add more than one flutter module to a single target. Currently flutter only supports one module per target.
• No caching is done for external sources, every time you run pod install flutter module will be downloaded each time.
