Centralize analytics tracking logic

Route all analytics events through a single service/helper instead of calling the SDK directly from widgets and blocs.

Why this matters

Avoids duplication, keeps event names/properties consistent, and makes it easy to swap providers or add privacy guards.

Bad vs. good

Side-by-side examples engineers can pattern-match during review.

Avoid

onPressed: () {
  AnalyticsSDK.track('button_tap', {'id': widget.id});
  // elsewhere
  AnalyticsSDK.track('button_tap', {'id': card.id});
}

Prefer

class Analytics {
  const Analytics(this._sdk);
  final AnalyticsSDK _sdk;
  void buttonTap(String id) => _sdk.track('button_tap', {'id': id});
}

onPressed: () => analytics.buttonTap(widget.id);

More snippets

Bad

AnalyticsSDK.track('x'); // scattered across UI

Good

analytics.doSomething(params); // via a single facade

Critical
Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Critical
Avoid Redundant `None` Comparisons
Identify cases where `x is None` or `x is not None` is used redundantly when `x` is always or never `None`. This may indicate a deeper logic issue.

High
Avoid Functions That Always Return the Same Value
Identify functions that return the same value regardless of input. This may indicate poor design or a logic error.
