Building Powerful Flutter Apps with Native Capabilities – The Askan Tech Approach

When it comes to mobile app development, Flutter has become a go-to framework for businesses seeking fast, beautiful, and cross-platform applications. At Askan Technologies, we leverage Flutter’s powerful toolkit to build scalable apps for both Android and iOS, but with an important twist. We know how to tap into the native power of each platform when needed.

Let’s talk about one real-world scenario that shows what Flutter can do, and where its native integrations take it even further.

The Real Challenge: Sharing Large Files via Bluetooth

Imagine you’re building an app that allows users to share large files between devices, something like the good old "SHAREit" app. Sounds simple? Well, here’s the twist.

Most of today’s sharing apps rely on native Bluetooth or Wi-Fi Direct to transfer large files seamlessly. But here’s the thing: Flutter by itself doesn't support all the deep Bluetooth-level operations required for such functionality.

Now, if you're a Flutter-only developer, you might hit a wall. But not us!

Our Smart Solution: Native Integration with Flutter

At Askan, we didn’t stop when Flutter’s default capabilities hit their limits. Instead, we went deeper, under the hood, and integrated Java for Android and Swift for iOS directly into our Flutter app using Flutter's Platform Channels.

This hybrid approach gave us the best of both worlds:

• Flutter's UI excellence and cross-platform codebase
• Native-level access to system services like Bluetooth and background tasks

What We Built: Seamless Bluetooth Sharing in the Background

Let’s walk you through what the solution looked like:

• A user selects a large file in our Flutter app
• The app turns on Bluetooth automatically (with permission)
• The file begins to transfer to the paired device—no third-party apps needed
• The app runs in the background, so the user can minimize it and continue using their phone without interruption
• Why This Matters for Your Business

If you’re planning to build a mobile app, Flutter is a smart choice; it saves time, cuts down on costs, and ensures consistent UI across platforms. But not every feature can be achieved with Flutter alone. That's where teams like Askan shine. We don’t just build apps. We engineer complete mobile experiences, combining Flutter with native code where necessary to give your users the performance and capabilities they expect.

Other Examples of Native Integration with Flutter

Apart from Bluetooth sharing, here are a few more places where native code supercharges Flutter apps:

• Accessing high-performance camera APIs
• Battery optimization and deep background services
• Native sensors (accelerometer, gyroscope, proximity)
• Secure biometric authentication (Face ID, fingerprint)

What is Flutter and Why Do We Use It?

Flutter is Google’s open-source framework for building cross-platform apps from a single codebase. That means faster development, lower cost, and consistent experiences across Android and iOS.

But what really makes Flutter a winner for us, and for our clients, are its smart features:

1. Widgets – The Building Blocks

Everything in Flutter is a widget! buttons, text, images, layouts.
Think of widgets like LEGO blocks, we stack and style them to build beautiful, interactive UIs that work across all devices.

2. Hot Reload – Speed Up Development

Flutter’s hot reload lets our developers see changes in real-time without restarting the whole app.
Want to tweak a design or fix a bug? Boom-instantly visible. This means faster testing, better feedback loops, and quicker time to market.

3. Single Codebase, Two Platforms

With Flutter, we write one set of code and deploy it to both Android and iOS.
It’s efficient, reduces bugs, and makes updates easier to manage. This also means less cost for our clients and faster delivery timelines.

4. Beautiful and Customizable UI

Flutter comes with a rich collection of widgets that look great right out of the box. But the real magic? We can fully customize everything to match your brand’s vibe. Smooth animations, clean layouts, and pixel-perfect designs, no compromises.

5. Access to Native Features

Need access to Bluetooth, Face ID, GPS, sensors, or background services? Flutter supports many native features via plugins.
And when something’s not available by default, we go straight to native Kotlin (Android) or Swift (iOS) and integrate it, seamlessly.

Final Thoughts

Flutter is powerful, but real magic happens when you know how to stretch its limits. At Askan Technologies, we do just that.

By combining Flutter’s brilliance with native Android and iOS code, we build high-performance, feature-rich apps that are built for the real world.
