Fix ExpressionChangedAfterItHasBeenCheckedError
in Angular
✅ Solution
The ExpressionChangedAfterItHasBeenCheckedError usually happens when a component's input changes after Angular's change detection cycle has already rendered the view. To fix this, consider using `setTimeout` to delay the change or implementing `OnChanges` to respond to input changes synchronously within the change detection cycle. Verify you're not performing actions that trigger further updates within the view rendering phase itself.
