Quick tip: Always use const widgets when possible

A reminder I keep giving myself: mark widgets as const whenever possible.

// Bad: Creates new instance on every rebuild
child: Icon(Icons.home)

// Good: Reuses the same instance
child: const Icon(Icons.home)

Why it matters:

• const widgets are created at compile time, not runtime
• They’re cached and reused, reducing memory allocations
• Flutter can skip rebuilding them entirely during reconciliation

Enable the prefer_const_constructors lint in analysis_options.yaml:

linter:
  rules:
    - prefer_const_constructors

Your IDE will then highlight every opportunity to add const. Small change, real performance gains.
