Comstor EDGE Focusmycomstoredge.com* I created a mobile application with Flutter / Dart.* I connected the mobile application to the existing Ruby on Rails application. I used the jsonapi-resource Ruby on Rails gem and Flutter pubs: japx, json_annotations, json_serializable.* I added flutter_bloc pub. This allowed us to develop a more dynamic UI without heavy loading of data from the server.* I developed HttpAuthClient to connect to Ruby on Rails devise gem. I used http_interceptor pub. I added TokenInterceptor to use devise_auth_token authorization scheme. The class puts a header with a token to the request and gets a header with a token from the response and the token saves to the secure storage.I left the project because the project manager with whom I worked for a long time left.
