Flutter is a framework for the creation of mobile applications. The asset is that it is an open-source framework. Google’s Dart programming language serves as the basis for it. If a mobile app developer desires to work on it, they need to know and learn Dart. Actually, it is not as difficult to learn. You can use it for developing cross-platform mobile applications just by a single codebase. So, you can now understand that there’s no need to write separate code for different platforms. Yes, you guessed it right – it saves money and time. The hot reload functionality allows you to rerun your app after any changes you make. The user interfaces built are flexible and have a native feel. Additionally, the Google community of developers will support whenever required.
