do not use build contexts across async gaps
I’m not entirely sure what context you are referring to, but if you are talking about asynchronous programming, then the phrase “do not use build contexts across async gaps” likely refers to the idea that data should not be shared between asynchronous operations that are not directly linked.
In asynchronous programming, it’s common to use “contexts” or “contexts objects” to store and pass data between asynchronous functions. However, it’s important to avoid using a context object in an asynchronous operation that is not directly related to the operation that created the context object. This is because async operations can be interleaved, and there is no guarantee that the same thread or process will execute each operation in order.
So, if you create a context object in one async operation and try to use it in another operation that is not directly linked, you run the risk of data corruption or unexpected behavior. It’s better to pass data between async operations using other mechanisms, such as function parameters or return values.
In summary, the advice to “not use build contexts across async gaps” means to avoid sharing data between asynchronous operations that are not directly related, to ensure that your code behaves as expected and avoids potential issues.

Build context Flutter
Flutter is an open-source UI framework developed by Google for building natively compiled applications for mobile, web, and desktop from a single codebase. It was first released in 2017 and has gained significant popularity among developers due to its fast development cycle, expressive and flexible widgets, and hot-reload feature.
Flutter is written in the Dart programming language and uses a reactive programming model. The framework provides a rich set of customizable widgets that can be used to build complex and beautiful user interfaces. These widgets are designed to be composable, which means they can be combined and reused to create complex UI elements.
One of the key benefits of Flutter is its fast development cycle. With the hot-reload feature, developers can see the changes they make to the code in real-time on their devices or emulators without having to restart the app. This makes it easy to experiment and iterate quickly on the app’s design and functionality.
Flutter also offers a rich set of tools and libraries that can be used to build and deploy apps for multiple platforms. With Flutter, developers can create apps for iOS, Android, web, and desktop from a single codebase. This significantly reduces development time and costs.
Overall, Flutter is a powerful and versatile UI framework that offers developers a fast and efficient way to build beautiful and functional apps for multiple platforms. Its flexibility, speed, and ease of use have made it a popular choice among developers and businesses alike.
