Modern applications need to know more than just what data currently looks like. They often need to answer questions such as: This is where audit logs become important. An audit log provides a historical record of important actions performed inside an application. When designed correctly, audit logging can improve security, debugging, compliance, accountability, and operational […]
When you write Flutter code, you usually think in terms of widgets: However, Flutter does much more behind the scenes before that Text appears as pixels on the screen. A simplified rendering pipeline looks like this: Understanding these stages is extremely useful when optimizing Flutter applications. For example, if an application is janky, the problem […]
Flutter is known for delivering smooth user interfaces, but even a well-structured app can experience performance problems when complex widgets are repainted more often than necessary. A small animation, timer, progress indicator, or frequently changing widget can sometimes cause a much larger section of the screen to repaint. This is where RepaintBoundary can help. RepaintBoundary […]
Flutter applications often become larger as new features, packages, images, fonts, and native SDKs are added. At first, a few extra megabytes may not seem important. However, app size can gradually become a real problem, especially for users with limited storage or slower internet connections. Fortunately, Flutter provides built-in tools for understanding what contributes to […]
A Flutter app can have fast API calls, clean state management, and efficient Dart code but still suffer from stuttering animations or scrolling. One possible reason is raster jank. Raster jank happens when Flutter prepares a frame on time, but the rendering work required to turn that frame into pixels takes too long. A simplified […]
A Flutter application can be functionally correct and still feel slow. You might notice: These problems are commonly described as jank. However, not all jank has the same cause. Two important categories Flutter developers should understand are: UI jank and raster jank. At a high level: Understanding the difference matters because optimizing the wrong part […]
Streams are one of the most important asynchronous programming concepts in Dart. While a Future produces a single asynchronous result, a Stream can deliver multiple values over time. For example: Whereas: Streams are commonly used in Flutter and Dart for: However, not every Dart stream behaves the same way. Two important types are: Single-subscription streams […]
Navigation is a fundamental part of almost every Flutter application. Even a relatively small app usually needs to move between screens such as: Flutter provides the built-in Navigator API for managing navigation. However, as applications become larger and require deep linking, authentication redirects, nested navigation, or web URL support, manually managing routes can become increasingly […]
Most Flutter applications are built around a simple assumption: The internet is available. A typical application works like this: This architecture works until the user’s network becomes slow, unstable, or completely unavailable. Then the application starts showing: An offline-first architecture approaches the problem differently. Instead of treating local storage as a temporary backup, the application […]
