Installing / Getting started

The application is available for Google Play.

Developing

Since the project is developed with the Flutter framework its environment must be built beforehand:

• Flutter 3.24.1
• Open JDK 22
• Android command line tools with some packages installed by its utility sdkmanager:
  • platforms, system-images and build-tools - their particular versions depend on what Android OS the application is supposed to be emulated on: the target version is 35, the minimal one is 21
  • cmdline-tools
  • emulator
  • platform-tools

To create an emulator for debugging run a command: avdmanager -s create avd -n -k "<system_images full pack name>" -d . The device number parameter is optional, to list such devices use a command: avdmanager list.

Visual Studio Code is used as an IDE with extensions:

• Dart
• Flutter

Configuration

The configuration file of the application is assets/cfg/params.json, it consists of the next parameters:

• The contacts section has options for setting up the respective expandable section on the panel with user preferences:
  • facebook_user_id is a FB user's id to render a link leading to the FB profile
  • email - an email for sending a report about bugs or propositions
  • app_store_id - for rendering a valid link to the application in Google Play.

A file assets/cfg/secret_params.json can be created with the same structure to keep parameters locally without tracking it in GIT.
