flutter_environment 0.0.2

A flutter package which allows you to manage build environment.

flutter_environment

Installation

1. Add this to your packages pubspec.yaml file:

dependencies:
  flutter_environment: <^last>

2. Install it You can install it from the command line:

$ flutter pub get

3. Import it Now in Dart code, you can use:

import 'package:flutter_environment/flutter_environment.dart';

Usage

Setup flutter_environment in your main function, we recommend you to set it at the top of your main to be able to use Environment.instance in any location of your app.

void main() {
  EnvironmentType environmentType = EnvironmentConfig.environmentType;
  Environment(
    environmentType: environmentType,
    color: Colors.red.shade900,
    values: EnvironmentValues(
      environmentType == EnvironmentType.dev
          ? 'https://www.duckma.org'
          : 'https://www.duckma.com',
    ),
  );
}

To set value based on environmentType, use Environment.instance.environment and use a switch like:

String _getSomeValue(EnvironmentType environmentType) {
  switch (environmentType) {
    case EnvironmentType.dev:
    case EnvironmentType.alpha:
      return 'Users angry';
    case EnvironmentType.beta:
    case EnvironmentType.prod:
      return 'Users happy';
  }
}

NOTE: This not possible for the EnvironmentValues.baseUrl since Environment is not initialized yet, so we make use of EnvironmentConfig.environmentType.

If you need to have more EnvironmentValues create an extension on it, we do this because singleton with static getter cannot deal with type paramiters.

extension EnvironmentValuesE on EnvironmentValues {
  String get envKey => 'DEV';

  String get userStatus => _getSomeValue(Environment.instance.environment);
}

Getting info

You can get information of the current EnvironmentType by using:

print('Is development environment: ${Environment.isDevelopment}');
print('Is alpha environment: ${Environment.isAlpha}');
print('Is beta environment: ${Environment.isBeta}');
print('Is production environment: ${Environment.isProduction}');

class Api {

  final baseUrl = Environment.instance.values.baseUrl;
}

Enjoy!
