ufrshubham/dino_run ? reverse-engineered prompt

Build me a simple Dino Run style game in Flutter, using Flame, where a little dinosaur runs forever across the screen and the player taps to jump over obstacles. It should have a main menu, a gameplay screen, and a game over state when the dino hits something. Keep the controls very easy for mobile, and make the game feel smooth and polished with basic animations, sound effects if possible, and a score that keeps going up the longer you survive.

Please make it work on Android and iPhone, and if it can also run on Windows that would be great, even if audio is limited there. Use the assets in the project if they are already there, and keep the code clean enough that I can understand and tweak it later. If anything needs a newer Flutter or Flame setup, please look up the current docs online and make it work with the latest stable versions.
