    Got some questions on your mind? Here are some frequently asked questions about our Flutter App Development Services that our experts have answered for you.

    Flutter app development is the process of building mobile, desktop and web browser applications using the Flutter framework. Flutter is an open-source User Interface toolkit from Google and it allows developers to write a single code and deploy it on diverse devices. This way, clients, Flutter app developers, product owners and businesses save time and financial resources.

    Yes, our team of Flutter app developers can convert your existing app into Flutter. The conversion process typically starts with a thorough code review with a strong flutter migration and conversion roadmap. The development and conversion time depend on size and architecture of your existing app, the quality of code, the technology stack previously used and the level of customization that your team and end users need.
    There are two logical measures how Flutter reduces the app development cost.

    Flutter apps are faster to build, especially if you are building a crossplatform app for two operating systems. Considering this, basic Flutter apps take 3 months in development. Multi-featured apps can take anywhere between 4 months to 7 months. More advanced apps can even take up to 9 months.  
    Yes, our Flutter developers use this framework for web development. We build commercial, large-scale organizational progressive web applications using Flutter.

    The hiring process at Trango Tech is super simple. There are two working arrangements we are currently following: you can outsource the flutter app project to our development team and communicate bi-weekly with our project manager. Secondly, you can hand-pick a development team on a subscription model.

    Yes, Flutter developers at Trango Tech can use Flutter to enhance the user interface, performance and functionality of your existing native app. The process starts with a thorough code review and product roadmapping with detailed recommendations on when and where in the existing code the Flutter’s components should be embedded.
