Bubble Blast | Flutter Mobile Game

Bubble Blast is a premium, fully-featured Bubble Shooter mobile game built entirely with Flutter and pure Dart — no third-party game engine required. It ships with 225 procedurally generated levels, a real-time programmatic audio engine, 4 power boosters, an in-game coin shop, 3 bubble skin themes, and a daily lucky spin wheel. The project is clean, well-commented, and publish-ready for both Google Play and the Apple App Store.

Features

Core Gameplay

• 225 Procedurally Generated Levels — 5 difficulty tiers from Easy to Expert. Every level is generated at runtime from a deterministic seed, so there is zero storage overhead and the layouts are always consistent.
• Precision Aim & Shoot — Smooth touch-drag aiming with a real-time aim-line guide and physics-accurate wall bouncing.
• 3-Star Rating Per Level — Stars are awarded based on remaining moves. Win and Lose overlays display stars earned, coins collected, and Retry / Next Level options.
• Combo & Strike Score System — Chaining large pop sequences builds score multipliers. Real-time score popup labels fly from the grid to communicate combo magnitude.
• Particle Burst & Gravity Drop Animations — Bubble pops trigger smooth particle-burst effects. Disconnected clusters fall with physics-based gravity animations at a buttery-smooth 60fps via Flutter’s Ticker.

Power Boosters

• Bomb — Explodes on impact and destroys all bubbles within a large radius. (150 coins)
• Fireball — Burns through every bubble in a straight line with no stopping. (200 coins)
• Rainbow — Removes all bubbles of any single color from the entire grid. (250 coins)
• Laser — Fires a precision beam that destroys a complete row of bubbles. (100 coins)

Progression & Rewards

• In-Game Coin Shop — Two-tab shop: Boosters and Bubble Skins. Players earn coins by completing levels and can spend them on power-ups or cosmetic skins.
• Daily Lucky Spin Wheel — 8-sector wheel rewarding 50–500 coins or a random booster (Bomb, Fireball, Rainbow, Laser). One free spin per day to encourage daily retention.
• 3 Bubble Skin Themes — Jewel (800 coins), Neon (1200 coins), and Candy (1500 coins). Each skin changes the visual style of all bubbles in the game.
• Persistent Player Progress — All data (level progress, coins, owned boosters, active skin, mute state, last spin date) is saved via SharedPreferences and restored on every launch.

Audio & UI

• Programmatic Synthesized Audio — All sound effects and background music are generated in real-time using Dart WAV synthesis. No audio asset files needed — lightweight and low-latency on physical devices.
• Mute / Unmute Toggle — Accessible on both the Home screen and the Game screen. State is persisted across sessions.
• Animated Home Screen — Floating candy-bubble background, animated logo with glow pulse, smooth button slide-in transitions, and a coins indicator.
• Responsive Portrait Layout — Works on all phone screen sizes from 5-inch Android phones to 6.7-inch Pro Max iPhones. Locked to portrait mode for consistent gameplay.
