fledge_render_flutter #

Flutter render backend for Fledge. Connects Fledge's render system to Flutter's rendering APIs.

Features #

• Canvas Backend: Stable rendering using Flutter's Canvas API
• GPU Backend: Experimental high-performance rendering (flutter_gpu)
• Backend Selection: Automatic fallback from GPU to Canvas
• Texture Management: Load and manage textures efficiently

Installation #

dependencies:
  fledge_render_flutter: ^0.1.0

Quick Start #

import 'package:fledge_render_flutter/fledge_render_flutter.dart';

// Select the best available backend
final backend = await BackendSelector.selectBest();

// Use it for rendering
final frame = backend.beginFrame(size);
frame.drawSpriteBatch(batch);
backend.endFrame(frame);

Backend Selection #

By default, BackendSelector.selectBest() tries flutter_gpu first (if available) and falls back to Canvas:

// Prefer GPU if available
final backend = await BackendSelector.selectBest(preferGpu: true);

// Force Canvas backend
final canvas = CanvasBackend();
await canvas.initialize();

Creating Textures #

final texture = await backend.createTextureFromData(
  TextureDescriptor(width: 256, height: 256),
  imageData,
);

Render Layers #

Organize rendering with layers:

final layer = RenderLayer(
  name: 'sprites',
  order: 10,
);

backend.submitLayer(layer);
