General Feature Flags

A robust, multi-provider feature flag system for Flutter. Professional, extensible, and corporate-ready.

Overview

general_feature_flags is a highly modular feature flagging solution designed for large-scale Flutter applications. It supports multiple providers, rollout strategies, user targeting, and experiments.

Motivation

Most feature flag solutions are tied to a single vendor (like Firebase Remote Config or LaunchDarkly). general_feature_flags provides a unified interface to use multiple providers simultaneously, with priority-based resolution and a clean 3-layer architecture.

Architecture

1. CORE: The engine, logic, and interfaces (general_feature_flags).
2. ADAPTERS: Vendor-specific implementations (Firebase, LaunchDarkly, Redis, HTTP).
3. EXTENSIONS: Custom implementations for your specific needs.

Comparison

Feature	Firebase Remote Config	LaunchDarkly	general_feature_flags
Multi-provider	No	No	Yes
Fallback logic	Limited	Yes	Advanced
Offline-first	Yes	Yes	Yes
A/B Testing	Yes	Yes	Yes
Custom API	No	No	Yes

Quick Start

final flags = FeatureFlagsClient();

await flags.initialize(
  providers: [
    FirebaseRemoteConfigProvider(...),
    HttpProvider(url: "https://api.myapp.com/flags"),
  ],
  userId: "user_123",
);

if (flags.isEnabled("new_feature")) {
  // Show new feature
}

Features

• Multi Provider: Merge flags from different sources.
• Priority: Define which provider takes precedence.
• Rollout: Percentage-based releases.
• Targeting: Target specific users based on attributes.
• Experiments: A/B testing support.
• Cache: Memory and persistent cache support.
• Debug: Override flags during development.
