// Example: Shared Widget - Trip Summary Card
// Path: lib/shared/widgets/trip_summary_card.dart
//
// This demonstrates a design-system-compliant SHARED widget:
// - Lives in shared/widgets/ because it's used across multiple features
// - All colors from AppColors
// - All spacing from AppSpacing
// - All radius from AppRadius
// - All typography from AppTypography
// - No hardcoded values anywhere

import 'package:flutter/material.dart';

// Shared design system imports

// import '../utils/constants.dart';
// import '../utils/typography.dart';

/// A reusable card widget for displaying trip information
/// 
/// This is a SHARED widget used by multiple features (trips, history, earnings).
/// Feature-specific widgets should live in their feature's view/widgets/ folder.
/// 
/// Usage:
/// ```dart
/// TripSummaryCard(
///   pickupAddress: '123 Main St',
///   dropoffAddress: '456 Oak Ave',
///   fare: 24.50,
///   distance: 5.2,
///   duration: 18,
///   onTap: () => navigateToTripDetails(tripId),
/// )
/// ```
