Mobile applications have seen tremendous growth, with the global mobile app economy growing from $1.31 trillion in 2016 to $6.35 trillion by 2022. Common platforms allow developing applications that work across different operating systems and devices. Flutter is a popular framework that uses its own rendering engine to develop high-quality, high-performance cross-platform applications from a single codebase for iOS and Android. It provides features like real-time updates, full control over pixels, custom branding, and faster development times compared to other technologies.
