gRPC + Flutter + Golang = 😎
---

This repository is a reference on how to start a Flutter project
with a custom backend based on gRPC and Golang.
It is (at least I believe so) not a spaghetti code, so it should be a great starter, and easy to extend.

It allows one to enter a query and send it with a request to the Golang backend server, which then performs it on Wikipedia to scrap information and return it as a result. All via gRPC.

How to launch it locally?
---

In order to make it work, you need to run Golang server `go run cmd/app/main.go` and then run Flutter app. 
If you want to make changes to `.proto` file and regenerate the code, I created a small bash script that does it for you.
All you have to do is execute `sh generate.sh` from the `proto` directory.

Quick demonstration
