Context

I plan to develop a real app, but it will take a lot of time, and due to personal reasons, there are chances it will never be released. I don't want to spoil here what this app will be about, but you can find some hints in this project. Before starting this app, I wanted to create a starter template to share my discoveries with people who learn these technologies.

I tried implementing clean architecture, but do not consider me an expert, I have always worked on small projects that didn't require it.

The frontend has no tests (feel free to add some!). The backend has 45 tests covering most of the code.

Installation and development

# Start by running db container
docker-compose up -d db
# Then back
docker-compose up -d backend

Backend commands

To be able to use sqlx cli tools

cargo install sqlx-cli --no-default-features --features postgres

To create a new migration file

sqlx migrate add name_of_your_migration
sqlx migrate run

Run locally on an external device

Change every occurrence of 192.168. somewhere in the code to match your IP.

Create frontend/.env on the model of frontend/.env.template changing the variable to match your situation (API_BASE_URL for instance).

Run on Android :

Make sure to follow the section ## Run locally on an external device first.

Turn on Developer Options and USB debugging “File sharing”.

Developer Options > Select USB Configuration > Change it from “File Transfer” (default option) to Charging”.

The phone will ask if you want to always allow USB debugging from this device.

Say yes.

Install android-studio from their web page.

Create a fake project.

From android-studio, Settings -> SDK Manager -> Languages & Frameworks -> Android SDK -> SDK Tools

Check Android SDK Command-line tools box.

Click Apply.

To check everything is fine: flutter doctor --verbose

To build the apk: flutter build apk --flavor dev --release

To install on device: flutter install --flavor dev
