 # Picker-Packer-App
 Picker & Packer Mobile App
+
+This is an application that will manage the preparation and delivery process of orders placed in e-commerce markets. The application includes 2 different modes, picker and packer.
+Picker is the mode that manages the preparation process of the orders, and Packer is the mode that manages the delivery process of the order to the customer.
+The functions of the application are in the slide or file in the "doc" section.
+A demo video is available at the link below.
+
+## Backend Development
+Python Flask was preferred as REST API Framework.
+SqlAlchemy (ORM) module, which is used to connect to the database and run the queries, is preferred for simplicity.
+Google Map APIs used for the map integration. (Google Map Directions and Google Map Distance Matrix APIs)
+Heroku and Render providers were preferred for deploying APIs in the cloud.
+PostgreSql was preferred as the database.
+
+## Frontend Development
+The widgets, models and animations provided by Flutter were used. 
+The development is based on the MVC model. 
+In the code, data is in classes called models, RESTAPI requests are in classes called provider, and interface pages are in classes called View.
+SnackBar, AlertDialog, Email Validator, AppBar, Navigation Bar, Refresh Indicator, Slidable, ListView, Call Launcher, Map Launcher, Barcode Scanner Image Picker, Page Transition, Geolocator, SpinKit Custom Loading, Others...

+# picker_packer
+
+A new Flutter project.
+
+## Getting Started
+
+FlutterFlow projects are built to run on the Flutter _stable_ release.
+
+### IMPORTANT:
+
+For projects with Firestore integration, you must first run the following commands to ensure the project compiles:
+
+```
+flutter pub get
+flutter packages pub run build_runner build --delete-conflicting-outputs
+```
+
+This command creates the generated files that parse each Record from Firestore into a schema object.
+
+### Getting started continued:
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://flutter.dev/docs/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://flutter.dev/docs/cookbook)
+
+For help getting started with Flutter, view our
+[online documentation](https://flutter.dev/docs), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.
