Flutter
Flutter is a modern toolkit created by Google for building mobile apps that work on both iPhones and Android phones at the same time. Instead of making two separate apps, developers can write the code once and have it work on both platforms. This saves companies time and money. Think of Flutter like a universal translator that helps create smooth, attractive apps that feel natural on any device. It's becoming increasingly popular because it's easier to maintain than traditional app development methods, and it allows for quick updates across all devices. Similar tools include React Native and Xamarin, but Flutter is known for creating particularly smooth and visually appealing apps.
