Our expertise with Flutter

So you’ve decided to build a Flutter app

  • number one


  • We set up an intro call to collect your high-level requirements on how the app should work and look like.
  • We provide you with preliminary time and cost estimate for the project.
  • Our business analyst collects your requirements, suggests how specific features can work and how the goals can be achieved. We create documentation for the software architecture and specifications.
  • EXISTEK’s UI/UX designers draw wireframes and mockups of each screen of the future app. You’ll have a functional prototype that represents the app look and user flow.
  • Upon the completion of the discovery stage, you get the final visual presentation and documentation that describes every bit of the application even before we start the development. That is how we ensure that the final result will meet all client's expectations.
  • number two


  • EXISTEK structures application development in sprints with the set of features that should be delivered under each milestone. The client has constant communication with the Flutter development team, weekly demos, and has access to the work-in-progress build on the device.
  • We use the Specifications Requirements Document created during the discovery stage to implement features and make sure that the app behaves as planned. The same document is used by the QA team to constantly test all the workflows in the application and report bugs that have to be fixed by the dev team.
  • EXISTEK uses Agile and Scrum as the main software development methodologies. Our project manager constantly reports progress to the client, collects feedback, and if needed, makes the changes to the development roadmap.
  • number three

    Support and updates

  • According to our standard contract, you have 30 days of the warranty period. All the bugs discovered during that time will be fixed by us for free immediately.
  • Upon the completion of the project, we can sign a Service Level Agreement for future fixes, updates, and new features or assign a dedicated team on our side who will continuously work on the future versions. You can be 100% sure that our Flutter app development company ensures that the team will support you after the launch and become your technology partner for the years to come.

More on Flutter mobile app development

Why is Flutter the best choice?

Many people refer to Flutter as to a framework. In fact, it is a Software Development Kit. SDK is a much broader concept. It includes frameworks, libraries, etc. Being an SDK raises Flutter app development to the next level. Flutter is extremely self-sufficient as it doesn’t require almost any third-party tools. This framework is as friendly as possible, which makes the Flutter app development process more comfortable for the IT specialists.

Why should we choose hybrid Flutter app development services instead of native?

Native apps used to be faster. But with a properly chosen framework, like Flutter, it is a non-issue. Hybrid development saves many resources for both sides: a Flutter mobile app development company and a client. Hybrid development means working with the single codebase (one app for both iOS and Android instead of two). It significantly reduces the development time and cost.

What is Flutter app development cost?

Development cost depends very much on many aspects: team composition, developers location, their experience, project complexity. EXISTEK, as a top Flutter development company, combines the best options of each criterion in order to deliver the optimum ratio Price-Quality. While working on a project, we form a team of the optimal size and choose the best technologies. With all that considered, we have about $40k - $80k for a project of medium complexity.
