What Makes This Special
Block Blast is not just another puzzle game template. It features a custom procedural audio engine (no audio files!), a particle explosion system, smooth neon aesthetics, and a clean layered architecture — all in one ready-to-publish Flutter package.

Core Features — Everything You Need, Out of the Box

No extra integrations, no broken dependencies. Build and run immediately on any platform.

Smooth Drag and Drop

Blocks float above the finger just like real Block Blast games. Ghost indicator shows exactly where the piece will land — green for valid, red for invalid.

Particle Explosion System

Every line clear triggers a burst of colored particles flying outward, plus a screen shake effect. Built with a custom painter — no external physics library needed.

Procedural Audio Engine

9 unique sounds + looping background music — ALL synthesized mathematically in Dart. Zero audio asset files. Keeps your APK lightweight and deployment friction-free.

Premium Neon UI

Deep dark background, electric color palette, glow effects, animated level progress bar, combo pop-ups, and score animations. Orbitron font throughout.

Combo and Level System

Combo multiplier rewards consecutive line clears. Every 1,000 points triggers a level-up with fanfare. Best score persists locally via SharedPreferences.

⚙️ Clean Architecture

Neatly separated into models, screens, widgets, and utils. No spaghetti in main.dart. Easy to extend, rebrand, or hand off to another developer.

Audio Engine — 9 Sounds + Music, Zero Files

All audio is generated using pure Dart math (sine waves, noise, envelopes). No MP3s, no OGGs, no asset pipeline headaches.

• Block Pickup Click
• Placement Thud
• Invalid Placement Buzz
• Line Clear Blast
• Big Blast (Multi-line)
• Combo Arpeggio
• Mega Combo Sweep
• Level-Up Fanfare
• Game-Over Melody
• Background Music Loop

How it works: The AudioService singleton synthesizes WAV bytes using Dart’s math library (sin, exp, noise). It encodes them as 16-bit PCM WAV in memory and plays via audioplayers. Background music loops automatically via the onPlayerComplete listener.

Multi-Platform — One Codebase, Four Platforms

Flutter handles platform-specific rendering. You get native performance on every OS with zero platform-specific code.
