Mobile App Development: Flutter vs React Native in 2024

Cross-platform mobile development has become the preferred approach for many businesses looking to reach both iOS and Android users efficiently. Flutter and React Native are the two leading frameworks in this space.

Flutter Overview

✅ Pros

• Compiled to native ARM code for excellent performance
• Rich widget library with beautiful material and Cupertino designs
• Hot reload for rapid development cycles
• Single codebase for mobile, web, and desktop

Flutter Code Example

// Flutter — Dart language
class ProductCard extends StatelessWidget {
  final Product product;
  const ProductCard({required this.product});

  @override
  Widget build(BuildContext context) {
    return Card(
      child: Column(
        children: [
          Image.network(product.imageUrl),
          Padding(
            padding: EdgeInsets.all(16),
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                Text(product.name,
                  style: Theme.of(context).textTheme.titleLarge),
                Text('€${product.price}',
                  style: TextStyle(color: Colors.green)),
              ],
            ),
          ),
        ],
      ),
    );
  }
}

React Native Overview

✅ Pros

• Uses JavaScript/TypeScript — familiar to web developers
• Huge ecosystem and community support
• Easy integration with existing native code
• Meta's continued investment and new architecture

React Native Code Example

// React Native — TypeScript
function ProductCard({ product }: { product: Product }) {
  return (
    <View style={styles.card}>
      <Image source={{ uri: product.imageUrl }} 
             style={styles.image} />
      <View style={styles.content}>
        <Text style={styles.title}>{product.name}</Text>
        <Text style={styles.price}>€{product.price}</Text>
      </View>
    </View>
  );
}

When to Choose Which

Choose Flutter if: You need pixel-perfect custom UI, your team can learn Dart, or you're building for multiple platforms including web and desktop.

Choose React Native if: Your team knows JavaScript, you need tight native integrations, or you want to share code with an existing React web app.
