Development Setup (FVM)

This repository pins Flutter via FVM in .fvmrc (3.41.4).

Run this single command from the project root:

make setup

This will:

• install the pinned Flutter SDK with FVM
• link the project SDK
• run pub get using the pinned SDK

To update the pinned Flutter version later:

make update-flutter VERSION=3.42.0

Then commit the updated .fvmrc.

Secrets with Doppler

Prism uses Doppler as the source of truth for runtime secrets. .env.example is reference-only and is not used as runtime input by Make targets.

Install Doppler CLI:

• https://docs.doppler.com/docs/install-cli

Run one-click setup from project root:

make setup-dev

This validates access to prism/dev, installs dependencies, and prepares local development.

Useful commands:

make doppler-login   # interactive Doppler login/setup
make secrets-print   # show available keys with masked values
make run             # run app with Doppler-injected dart-defines

Release workflows use Doppler Service Tokens (GitHub secret: DOPPLER_TOKEN_PRODUCTION). See detailed guide: docs/development/doppler.md.

Usage

The application files for Android devices can be found on Google Play Store.

More information about the releases can be found in the Release tab.
