Config Variables for your Flutter apps #

Plugin that exposes environment variables to your Dart code in Flutter as well as to your native code in iOS and Android.

Inspired by react-native-config

Basic Usage #

Create a new file .env in the root of your Flutter app:


load all environment varibles in main.dart

import 'package:flutter_config/flutter_config.dart';

void main() async {

  await FlutterConfig.loadEnvVariables();


Now you can access your environment varibles anywhere in your app.

import 'package:flutter_config/flutter_config.dart';

FlutterConfig.get('FABRIC_ID') // returns 'abcdefgh'

Keep in mind this module doesn't obfuscate or encrypt secrets for packaging, so do not store sensitive keys in .env. It's basically impossible to prevent users from reverse engineering mobile app secrets, so design your app (and APIs) with that in mind.

Getting Started #

Install the latest version of the plugin

Refer to Android Setup Guide for initial setup and advanced options

No additional setup is required for iOS, however, for advanced usage refer to the iOS Setup Guide

Testing #

Whenever you need to use FlutterConfig in your tests, simply use the method loadValueForTesting

import 'package:flutter_config/flutter_config.dart';

FlutterConfig.get('FABRIC_ID') // returns 'abcdefgh'

void main() {
  FlutterConfig.loadValueForTesting({'BASE_URL': 'https://www.mockurl.com'});
  test('mock http client test', () {
    final client = HttpClient(
      baseUrl: FlutterConfig.get('BASE_URL')
