How to Make a Fashion App App with Flutter

Size Recommender

class SizeRecommendation {
  final String recommendedSize;
  final double confidence;

  SizeRecommendation({required this.recommendedSize, required this.confidence});
}

SizeRecommendation recommendSize({
  required double heightCm,
  required double weightKg,
  required String gender,
  String? previousSize,
}) {
  // Simple heuristic: BMI-based size suggestion
  final bmi = weightKg / ((heightCm / 100) * (heightCm / 100));

  String size;
  if (bmi < 18.5) size = 'XS';
  else if (bmi < 22) size = gender == 'male' ? 'S' : 'S';
  else if (bmi < 26) size = gender == 'male' ? 'M' : 'M';
  else if (bmi < 30) size = gender == 'male' ? 'L' : 'L';
  else size = 'XL';

  return SizeRecommendation(
    recommendedSize: previousSize ?? size,
    confidence: previousSize != null ? 0.9 : 0.7,
  );
}

class SizeCard extends StatelessWidget {
  final SizeRecommendation rec;
  const SizeCard({super.key, required this.rec});
  @override
  Widget build(BuildContext context) {
    return Card(
      color: Colors.pink.shade50,
      child: Padding(
        padding: const EdgeInsets.all(16),
        child: Row(
          children: [
            Icon(Icons.check_circle, color: Colors.pink.shade300, size: 32),
            const SizedBox(width: 12),
            Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                Text('Recommended size: \${rec.recommendedSize}',
                  style: const TextStyle(fontSize: 18, fontWeight: FontWeight.bold)),
                Text('\${(rec.confidence * 100).toStringAsFixed(0)}% confidence',
                  style: TextStyle(color: Colors.grey.shade600)),
              ],
            ),
          ],
        ),
      ),
    );
  }
}

UI & UX Suggestions

Use a pink/rose gold primary, white cards, black product images colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
