Why Flutter Is The Best For Stock Market Trading Mobile Applications
A mobile application can have various functionalities, including:
- Image Processing (Camera-related applications)
- Location and Maps (GPS-related applications)
- Video Processing (Video editing-related applications)
- API-Based Applications (Fetching and displaying data from APIs)
- Game Development
- Embedded Application Development
If your application heavily interacts with hardware, such as using the camera, GPS, or video processing, building it in Kotlin (for Android) or Swift (for iOS) would be more beneficial. These languages directly interact with the hardware and provide tools and libraries to those specific functions.
However, if your application primarily involves fetching and displaying data from APIs, then Flutter is a highly recommended framework. Here’s why:
Why Flutter Works Well For Trading Applications
A trading application usually involves:
- Watchlist Management (Fetched from an API)
- Placing Orders (Using APIs)
- Viewing Orders, Holdings, and Positions (Fetched via APIs)
- Local Database Management
- Other API-Related Operations
- Live Data Feeds (Using WebSocket)
As you can see, the majority of tasks in a trading application revolve around API interactions—fetching, displaying data, and sending commands to servers. Here’s how Flutter excels in these areas:
Flutter’s Hot Reload feature significantly speeds up the stock market app development process, allowing developers to see changes instantly. This makes UI building and testing much faster, which is why we managed to rebuild our trading app in just 7 months compared to the previous 1.5 years it took with Kotlin.
