dotenv_gen 0.0.2

Generate environment variable dart files from an `.env` file.

A code generation library to make enviroment variables available at compile time.

Features

Generates a dart file with values from a .env file allowing you to use those enviroment variables in your project without commiting them. Supports and parses not just String but also int, double, bool and enum.

Getting started

Add the following to your projects pubspec.yaml

dependencies:
  dotenv_gen: any

dev_dependencies:
  dotenv_gen_runner: any
  build_runner: any

Usage

Add a .env file at the root of the project. Syntax and rules for the file can be viewed at dotenv rules.

name=EnvGenTest

Create a dart file with your .env keys. Supported variable types are:

• String
• int
• double
• bool
• enum

import 'package:dotenv_gen/dotenv_gen.dart';

part 'example.g.dart';

@DotEnvGen()
abstract class Env {
  // factory to init the generated class
  const factory Env() = _$Env;

  // an empty constructor is required
  const Env._();

  // value is required
  String get name;

  // use default value if no value provided
  final int version = 1;

  // null if no value provided
  String? get description;

  // any functions etc will be inherited
  void func() {}
}

Then run the generator:

# dart
pub run build_runner build
# flutter
flutter pub run build_runner build

Issues

Changing values in the .env file and re-running build_runner may not update file due to a caching
