Feature Flags in Flutter

Installation

$ flutter pub add feature_flags_toggly

This will add a line like this to your package's pubspec.yaml (and run flutter pub get):

dependencies:
  feature_flags_toggly: ^0.0.1

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Now in your Dart code, you can use:

import 'package:feature_flags_toggly/feature_flags_toggly.dart';

Basic Usage

Initialize Toggly by running the Toggly.init method and by providing your App Key from your Toggly application page

@override
void initState() {
  initToggly();
  super.initState();
}

void initToggly() async {
  await Toggly.init(
    appKey: '<YOUR_APP_KEY>',
    environment: '<YOUR_APP_ENVIRONMENT>',
  );
}

Now simply wrap your widgets in Feature widgets and provide them with the featureKeys that best describe them.

Feature(
  featureKeys: const ['ExampleFeatureKey1'],
  child: const Text('This text will show if ExampleFeatureKey1 is FALSE'),
),

You can also use multiple feature keys for one Feature widget and make use of the requirement (FeatureRequirement.all, FeatureRequirement.any) and negate (bool) options.
