Bet55

Bet55 is a Flutter-based mobile application designed as a tactical free-kick defense simulator and skill-based sports arcade. The codebase is organized into modular directories including defensive_chassis for app bootstrapping, state persistence, and routing, stadium_panoramas for navigation and onboarding flows, glove_dynamics for core game loop physics, and clean_sheet_scrolls for achievement management. The application's UI is styled using custom Canvas drawing operations via CustomPainter to render geometric dashboard panels, sports-inspired angular navigation buttons, and stadium-themed overlay grids with official championship gold, deep blue, and emerald green colors.

The underlying gameplay mechanics are driven by gesture-based input detecting horizontal drags to reposition a defensive wall block at the bottom of the field. Incoming soccer projectile paths are simulated using Bezier curves to model professional swerving free-kick vector trajectories, incorporating speed multipliers and sequence matrices to form progressive difficulty levels. Game states, high scores, earned tournament tokens, and tactical upgrades (such as block extension widths, recovery height, and impact absorption) are locally persisted via the shared_preferences library, allowing persistent progression across application sessions without external database dependencies.
