![]() ![]() In the context of a Flutter app, this means that the app can automatically update the user interface based on changes in the underlying data. The BLoC pattern is based on the concept of reactive programming, which involves building systems that can automatically respond to changes in data. It eases the testing and scaling of the app over time. This separation of concerns helps improve the overall structure and maintainability of the code. The BLoC (Business Logic Components) is a design pattern that allows developers to separate the business logic and presentation layers of their Flutter app. ![]() We will also see the use of streams and sinks to communicate between the presentation layer and the business logic. We will then delve into the process of setting up a Flutter project with the BLoC pattern. We will begin by understanding the key concepts of the BLoC pattern and how it fits into the overall architecture of a Flutter app. One popular choice for architecture in Flutter is the BLoC (Business Logic Components) pattern. One key aspect of building high-quality Flutter apps is implementing a robust architecture. In addition, Flutter has been recognized as a top-performing framework regarding developer satisfaction and adoption by multiple industry reports, such as the "2020 Developer Survey Results" by Stack Overflow and the "2021 Mobile App Development Frameworks" report by GoodFirms. Nearly 90% have reported being "satisfied" or "very satisfied" with Flutter. It allows developers to build natively compiled mobile, web, and desktop applications from a single codebase.Īccording to the latest survey conducted by Google, over 50% of Flutter developers have been using the framework for less than a year. Flutter is a highly popular open-source mobile application development framework created by Google. ![]()
