If you've come across this error while developing your Flutter application, don't worry! We'll walk you through what it means, why it happens, and most importantly, how to solve it. Flutter is a popular framework for building cross-platform mobile applications. It allows developers to write code once and deploy it on both Android and iOS devices. However, working with asynchronous operations in Flutter can sometimes lead to errors, and one of the most common ones is the 'await' can only be used within an async function error.
