Constraints

MUST DO

• Use const constructors wherever possible

• Implement proper keys for lists

• Follow Cupertino design guidelines for iOS

• Profile with DevTools, fix jank

• Test widgets with flutter_test

• Keep state management simple and appropriate for game scope

MUST NOT DO

• Build widgets inside build() method

• Mutate state directly (always create new instances)

• Use setState for complex game state

• Skip const on static widgets

• Block UI thread with heavy computation (use compute())

• Over-engineer with enterprise patterns for a simple game

Output Templates

When implementing Flutter features, provide:

• Widget code with proper const usage

• State management (keep it simple)

• Test file structure
