Welcome to Game Framework

Game Framework is a unified framework for embedding game engines into Flutter applications. Seamlessly integrate Unity and Unreal Engine games with bidirectional communication, lifecycle management, and multi-platform support.

Why Game Framework?

Key Features

Unified API

Single, consistent API for all game engines. Write once, work with Unity or Unreal Engine without engine-specific code.

Lifecycle Management

Automatic pause/resume/destroy handling with full control over engine lifecycle from Flutter.

Multi-Platform Support

Deploy to Android, iOS, macOS, Windows, and Linux with platform-optimized integrations.

Production Ready

Comprehensive testing, documentation, and real-world usage in production applications.

Automated Tooling

CLI tools for exporting games, syncing files, building apps, and publishing packages to the cloud.

Cloud Publishing

Publish your game packages to Game Framework Cloud with workspace management and version control.

How It Works

Game Framework consists of three main components:

• gameframework SDK - Core Flutter package with unified engine API
• Engine Plugins - Unity and Unreal Engine specific integrations
• game-cli - Command-line tool for exports, builds, and publishing

import 'package:flutter/material.dart';
import 'package:gameframework/gameframework.dart';

class GameScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: GameWidget(
        engineType: GameEngineType.unity,
        config: GameEngineConfig(
          runImmediately: true,
        ),
        onEngineCreated: (controller) {
          // Send messages to your game
          controller.sendMessage('GameManager', 'Start', 'level1');
        },
        onMessage: (message) {
          // Receive messages from your game
          print('Message from engine: ${message.data}');
        },
      ),
    );
  }
}
