🎨 Skribbl.io Flutter Clone

A real-time multiplayer drawing and guessing game built with Flutter and Firebase Realtime Database.

---

🚀 Key Features

• Real-Time Multiplayer: Seamless room creation and joining via a 6-character room code. Fully synced game phases (Lobby, Choosing Word, Drawing, Score Reveal, and Podium).
• Normalized Canvas: Brush strokes are sent to Firebase as normalized percentages ($0.0 - 1.0$) and scaled locally, ensuring perfect rendering across all device screen sizes.
• Typo-Tolerant Chat: Utilizes Levenshtein Distance to detect close guesses (within 2 characters). It privately notifies the guesser they are "Close!" without leaking the answer to others.
• Dynamic Scoring: Correct guessers are scored based on elapsed time (up to 150 pts) with active streak multipliers. The drawer is scored proportionally to the number of successful guessers.
• Procedural Avatars: Built-in visual editor using CustomPainter to procedurally render player avatars (18 colors, 10 eye types, 10 mouth shapes).
• Bot Simulation: Simulates automated guesses and preset drawing coordinates for solo practice sessions.
