What we check
Contents of our proven Flutter Code Assessment
Code quality
We check code quality by looking for clear structuring, clean formatting, consistent naming conventions, and readability-optimized code.
Architecture & Pattern
We make sure that architectural principles such as MVC (Model-View-Controller), MVVM (Model-View-ViewModel) or BLoC (Business Logic Component) have been implemented correctly and that they contribute to the scalability and maintainability of the app
Usability
We verify that the app’s user interface is designed to be user-friendly and complies with Flutter’s overall design guidelines, ensuring clear navigation, intuitive controls, and a smooth user experience.
Performance
We check the performance of the app, optimizations like caching data, lazy loading or using Flutter’s performance tools have been implemented to ensure a responsive app with high performance.
Testing
We look at whether the most important functionalities and scenarios of the app are covered by tests, e.g. in the form of unit tests, integration tests and widget tests. The goal is to ensure the robustness and stability of the app.
Documentation
We check that the code is adequately documented, e.g. in the form of comments, descriptions of functions and classes, or instructions for use, with the aim of making it easier for other developers to understand and collaborate.
Further
Many other components, depending on the individual situation. With the goal of ensuring a robust and successful app.
