Flutter MVP development: how to avoid common mistakes and achieve success

A significant factor in the explosive growth of the mobile app market, Flutter is an open-source UI toolkit created by Google. The portability of the platform makes it possible for developers to create programs that function consistently in various environments. To fully realize the benefits of Flutter, however, careful architectural planning is required.

The flutter for MVP development pattern proves to be a reliable alternative compared to the other architectural ways available. In this course, you will learn the fundamentals of Flutter, as well as the best practices for designing a minimal viable product (MVP). According to a survey of global developers conducted in 2022, 46% of software developers utilized Flutter.

What does Minimum Viable Product (MVP) Development in Flutter entail?

The Model-View-Presenter (MVP) architectural pattern and approach is used by many Flutter app developers to build reliable applications, quickly updated and tested. The advantages of this design stem from the fact that the Model, the View, and the Presenter must all play distinct but complementary roles. When the functions of each architectural part are well-defined, the resulting code base is more organized and efficient.

➤ Model: The Model is an abstract data representation of the app’s data and logic. Data retrieval, storage, and the implementation of business rules are all under its purview. The Model is respontracks and reactschanges and app state transitions in Flutter.

➤ View: The see is the software’s presentation layer where the user may see the application’s graphical user interface. Information is shown, and the user’s selections and form submissions are tracked. The look and functionality of a Flutter app are determined by the widgets used to build its Views.

➤ Presenter: The Presenter displays information from the Model and the View. On the controller, users may make changes and see the effects of those changes on the Model and the View. The Presenter makes sure the Model and View are kept apart so that the code is simpler to maintain and test and to help separate responsibilities.

Avoiding Flutter MVP development mistakes

1. Limited Disconnect

Limited Disconnect happens when two or more components of your program, such as the View and the Presenter, are inseparably intertwined and, as a result, cannot be updated separately. This makes your code less flexible and more vulnerable to attacks.

In Flutter for MVP development, the View and Presenter may be closely connected only if they exchange data. The Presenter and the View widget become tightly coupled when, for example, the View widget calls methods on the Presenter. As a result, it might be easier to replace or upgrade a particular component by also influencing the others.

➤ Solution: Limited Disconnect makes your code less modular and harder to maintain. Writing unit tests is challenging because of the difficulties in separating and testing individual components. Using interfaces or abstract classes to construct contracts between the View and Presenter helps establish a clear separation of duties and makes your code more flexible.

2. Oversized Gadgets

When widgets are asked to do many functions simultaneously, such as displaying UI components and incorporating complex business logic, they tend to balloon in size. This violates the “separating concerns” principle, which might lead to unwieldy source code.

The display of UI elements and the processing of events should be top priorities for Flutter app development. When widgets include business logic and user input, it becomes more challenging to reuse them throughout your application and keep them updated.

➤ Solution: Modularity and reusability are improved when the user interface is separated from the business logic. Focusing on the aesthetics of the user interface makes for more straightforward, easier-to-update widgets. You may simplify testing and maintenance by relocating the business logic to the Presenter or other specialized classes.

3. Not Enough Tests

Avoiding testing is the same as not seeing whether your code works as intended. This might cause issues along the road that would be difficult to identify and fix. Your Flutter MVP will fail if your Presenter and Model classes don’t work as intended and your UI components don’t display and interact as intended.

➤ Solution: You may be sure that your code is performing as expected if you catch and fix any issues quickly via testing. Unit tests for business logic and widget testing for UI components allow for early detection and resolution of problems before they affect users. Test-driven development (TDD) is a technique to create better, more reliable code.

4. Overuse of the StatefulWidget component

Using StatefulWidget is only sometimes necessary, and doing so may lead to a cumbersome and inefficient widget tree. The Flutter library StatefulWidget is the best option if you need to deal with the mutable state that influences the UI. However, it might introduce unnecessary complexity if it’s utilized for widgets that don’t need state changes.

➤ Solution: If a widget doesn’t need access to a changeable state, moving to a StatelessWidget might simplify and speed up its management. The resulting codebase complexity and performance could be reduced. You should only use StatefulWidget if you need to.

5. Skipping Injections of Dependence

With dependency injection, it’s easier to effectively manage components’ reliance on one another. This might lead to tightly coupled code that is difficult to test and modify.

Your Presenter and Model classes in Flutter MVP could often need external resources like services and data providers. Skipping the dependency injection framework leads to a complex web of interdependencies.

➤ Solution: Frameworks that allow dependency injection, such as get_it and provider, make it easier to keep track of dependencies in a tidy way. They allow you to define dependencies in one place and then share that information with the appropriate sections of your system. This promotes modularity and makes replacing components during testing and upgrades easy.

6. Neglecting to maximize performance

The performance of your program suffers if you put off adjusting it. This may slow down page loads and affect responsiveness. Flutter’s speed may be optimized in several ways, but two of the most important are reducing the amount of memory used and enhancing the display of lengthy lists or complicated UIs.

➤ Solution: Customer satisfaction may be directly tied to a product’s performance. Users need an app that loads quickly and operates smoothly. By profiling and optimizing the most crucial parts of the code, you could enhance the user experience of your software.

7. Poor Design and Usability

To elaborate, cutting corners on UI/UX design does not give any thought to how the program will look or behave when used. This may cause developers to create apps that no one wants to use. Adhering to design standards and creating an approachable and visually beautiful user interface may increase user engagement with Flutter.

➤ Solution: It’s possible that improving the app’s UI and UX may increase its popularity and success. Your app’s success will be directly proportional to the work and care you put into its layout. Taking the time to learn about these common problems and the reasons why you should avoid them will make your Flutter MVP easier to maintain, more efficient, and more user-friendly.


Flutter for MVP development needs best practices and avoiding pitfalls. Addressing these difficulties lets you build high-quality, stable, efficient apps with great user experiences. Code modularity and stability are promoted by avoiding tight coupling, focusing widgets on UI display, and testing.

Performance optimization and dependency injection make your program scalable and real-world-friendly.

UI/UX design and user input are crucial to designing applications customers enjoy and utilize. Long-term mobile app development success requires continuous learning and Flutter ecosystem updates.
