FullStack Labs is a leading team of Flutter developers, engineers, programmers, coders, and architects. Uber, Siemens, and hundreds of other companies have chosen us for their mission-critical Flutter development projects.
We’ll review your code base and provide a report that includes quality scores for the following:
We design and build greenfield apps of all shapes and sizes using Flutter combined with a Python, Node, or Ruby on Rails backend.
Have a legacy Flutter app? We’re here to help. From debugging and maintenance to feature development and DevOps, we'll tailor a development plan to meet your needs.
Need to add a Flutter developer to your existing team? We'll seamlessly integrate as many developers as needed, to help you go faster and level up your team's skills.
We will work with you to understand your technical needs, team dynamics, and goals.
We’ll send you FullStack Flutter developers that match your technical requirements, with links to their FullStack profile page which outlines their work experience and technical abilities, as well as their FullStack technical summary page, which includes a 60 minute video of the developer completing FullStack’s coding challenge, and a plethora of other technical information from their interview with us.
Start the engagement. Work with your new Flutter developers for a trial period, ensuring they're the right fit.
We’d love to learn more about your project.
Engagements start at $75,000.
FullStack Labs is a leading team of software developers, engineers, programmers, coders, and architects. Uber, Siemens, and hundreds of other companies have chosen us for their mission-critical software development projects. Flutter is a crucial tool to develop your project, here are a few Flutter Interview Questions you can use to screen your Flutter candidates:
Q: There is a text-overflow on some narrow devices. How would you fix this?
Answer:
When a Row’s child is wrapped in an Expanded widget, the Row won’t let this child define its own width anymore.
Instead, it defines the Expanded width according to the other children, and only then the Expanded widget forces the original child to have the Expanded width.
In other words, once you use Expanded, the original child’s width becomes irrelevant and is ignored.

Q: What are extensions, and how do we create one?
Answer:
Extension methods make it possible to add new functionalities to any type, even those from the foundation.
They were introduced in Dart 2.7 and are already available to use in Flutter as well.
Q: What is a ‘Future’ in Dart?
Answer:
A future represents the result of an asynchronous operation, and can have two states: uncompleted or completed.
A future of type Future<T> completes with a value of type T. For example, a future with type Future<String> produces a string value.
If the asynchronous operation performed by the function fails for any reason, the future completes with an error.
Q: What widget is typically used to provide safe area support?
Answer:
SafeAreaWidget
Q: What is null-safety introduced in Flutter 2.0?
Answer:
When you opt into null safety, types in your code are non-nullable by default, meaning that variables can’t contain null unless you say they can. With null safety, your runtime null-dereference errors turn into edit-time analysis errors.
Q: What are the available web renderers we can currently use?
Answer:
When running and building apps for the web, you can choose between two different renderers. The two renderers are: HTML renderer. Uses a combination of HTML elements, CSS, Canvas elements, and SVG elements. This renderer has a smaller download size.CanvasKit renderer. This renderer is fully consistent with Flutter mobile and desktop, has faster performance with higher widget density, but adds about 2MB in download size.
Q: Which method is used to cancel the animations and unsubscribe stream?
Answer:
Note: The dispose method is called when the State object is removed, which is permanent.
