A Dart/Flutter package for loading .env files and generating a Dart file containing environment variables with static getters. This package simplifies the management of environment variables and helps automate the process of accessing them within your project.

• Loads .env files and parses them into a Map<String, String>.
• Generates a env.dart file with static getters for each environment variable.
• Automatically inserts the import statement and Env.init() initialization in main.dart.
• Supports custom paths for the env.dart file.

Add the following to your pubspec.yaml file:

dependencies:
  tarsier_env: ^1.0.0

Then run this command:

flutter pub get

The dart run tarsier_env <command> <optional> syntax maps directly with required commands (generate, new). Optional is when you use command generate for custom path.

• Generates a default .env file with basic content, including a placeholder for your app name. Automatically checks if .env is listed in .gitignore and adds it if not already present.

dart run tarsier_env new

This will generate a .env file in the root directory with the following content:

# AUTO-GENERATED FILE. 
# YOU CAN EDIT/ADD MORE KEYS AND ITS VALUE.
# Generated by tarsier_env script.

APP_NAME="Tarsier"
APP_ENV=local
APP_KEY=null
APP_DEBUG=true
APP_URL=http://localhost

...

• Generates a env.dart file containing static getters for environment variables from your .env file. Automatically imports env.dart. Inserts await Env.init(); in the main() function of main.dart.

  • If no path is provided, the generated file will be placed in lib/env.dart.
  • If a relative path under the lib directory is provided, the file will be placed in the corresponding subfolder.

dart run tarsier_env generate common/environment

This will create lib/common/environment/env.dart with the environment. After running above code, you can access the environment variables in your Flutter app as follows:

In your main.dart, ensure the Env.init() method is called before using any environment variable.
