Relatively fast development, which saves you time, effort, and money (at least at the very beginning, but we will get to that). Like any other cross-platform technology, it allows you to use the same code base for building separate iOS and Android apps.
Flutter’s “hot reload” makes it possible to make changes to the code and see the results immediately in the app preview, without the need to recompile the code. This way, you can easily fix bugs and experiment with different UI elements and features once you’re at it.
Full customisation & fast rendering thanks to Flutter’s layered architecture. It’s said to “give you control over every pixel on the screen” and let you overlay & animate graphics, video, text and controls without limits.
Flutter also works for web and offers proper documentation, allowing you to check how native controls work.
Cons
Flutter is still an immature framework. It hasn’t been around for long, which is why it’s still not entirely stable. A number of more or less problematic issues remain, along with a lack of more advanced features that leverage the capabilities of operating systems.
Dart is also pretty immature. When comparing it to Swift and Kotlin, it’s basically like taking a step back - it has either fewer features or the existing ones are not exactly well-refined.
Flutter apps are quite large and “heavy” to start with. They occupy a lot of space and take longer to download or update.
The look & feel is not 100% the same as with native solutions. Basically, Flutter doesn’t create native components. It somewhat replicates Android’s Material Design and iOS-specific components with its Cupertino library, but it’s not exactly the same.
