Code Optimization

Optimization Process

1. Profiling (Find Bottlenecks)

Flutter DevTools:

# Flutter SDK lives on Windows — run via powershell.exe from WSL:
powershell.exe -Command "cd '$(wslpath -w "$PWD")'; flutter run -d windows --profile"
# Open DevTools and analyze:
# - CPU Profiler
# - Memory
# - Performance overlay

Metrics to Track:

• Frame rendering time (< 16ms for 60fps)
• Memory usage
• Widget rebuild count
• App startup time

2. Algorithm Optimization

Complexity:

Before	After	Example
O(n²)	O(n log n)	Sorting
O(n²)	O(n)	Nested loops → Map/Set
O(n)	O(1)	Linear search → HashMap

Examples:

// BAD: O(n²)
for (final item in list1) {
  if (list2.contains(item)) { ... }
}

// GOOD: O(n)
final set2 = list2.toSet();
for (final item in list1) {
  if (set2.contains(item)) { ... }
}

3. Memory Optimization

Avoid:

• Creating objects in loops
• Copying large collections
• Holding references to unused objects
