Rushabh PatelFlutter is an open-source mobile application development SDK created by Google. It’s widely used to build cross-platform apps for Android and iOS, and it’s emerging as a go-to solution for businesses aiming to reach a broader user base with a single codebase. Flutter enables developers to create natively compiled applications from a single codebase, embracing the principle:
“Write once, run anywhere.”
Why Flutter for Mobile Application Development?
If you’re exploring modern tools for mobile development, Flutter app development offers a solid foundation. Let’s explore why so many Flutter application development companies choose this SDK for cross-platform mobile app development.
1. Cross-Platform Development
Developing apps separately for Android and iOS can be time-consuming and expensive. Flutter simplifies this by offering cross-platform capabilities—you can create a single app that works seamlessly on both platforms. If you’re just starting out, Flutter provides intuitive tools that reduce development complexity and cut time-to-market.
For developers also exploring native Android apps, here’s a look at our Android app development services.
2. It’s Lightning Fast
Speed matters. Flutter’s “hot reload” feature allows developers to instantly view changes in the code, making it easier to experiment, build UIs, add features, and fix bugs without restarting the app. This leads to significantly faster development cycles.
“Hot reload” is a game-changer for real-time feedback and rapid iteration.

3. Support for Older Devices
App developers often worry about how apps will perform on older OS versions. Flutter handles this with ease—your app will look and function consistently even on older versions of Android and iOS.
- Saves developer time
- Reduces long-term support costs
- Ensures a consistent user experience
Plus, there are no extra costs for supporting legacy systems—an important consideration for budget-conscious businesses.
4. Exceptional User Experience
Flutter uses customizable widgets to build UIs. Unlike other frameworks that rely on native components, Flutter renders everything from scratch. That means:
- A consistent and smooth UI across platforms
- Access to a wide array of widgets for layout, animation, and interaction
- High-quality designs using Material Design (Android) or Cupertino (iOS) widgets
Everything in Flutter is a widget—from buttons to padding and fonts—allowing a modular and flexible approach to UI development.
Planning ahead is crucial, especially for large apps, as widgets are structured hierarchically.
5. Budget-Friendly Development
With Flutter, you only need to maintain one codebase. That means:
- Fewer developers
- Shorter development cycles
- Lower development and maintenance costs
This makes Flutter an ideal choice for startups and enterprises alike, looking to build Android and iOS apps within budget.

6. Backed by Google
Since Google created Flutter and uses it in its own products (like Google Ads and Fuchsia OS), you can rest assured that:
- Flutter will receive long-term support
- Frequent bug fixes, performance improvements, and updates will be released
- The SDK will continue to evolve with the industry
When you choose Flutter, you’re choosing a technology backed by one of the biggest names in tech.
7. Flutter 2 and Beyond
The release of Flutter 2 marked a shift from mobile-only to multi-platform development. Today, you can use Flutter to create apps for:
- Linux, Windows, and macOS
- Web applications
- IoT devices and wearables
Flutter is no longer limited to mobile—it’s evolving into a unified development platform for building apps across a wide range of devices.
According to Google’s official blog, Flutter 2 allows developers to go beyond mobile into desktops, embedded devices, and the web.
8. Ideal for MVP Development
If you’re a startup, launching with an MVP (Minimum Viable Product) is a smart way to:
- Validate your business idea
- Gain early feedback
- Attract potential investors
Flutter’s ease of use, fast development time, and attractive UI components make it an ideal framework for MVP development. Its developer-friendly ecosystem enables small teams to ship feature-rich MVPs quickly.
How the Flutter Framework Works
Understanding how Flutter works under the hood can help developers make better use of its tools. The framework is composed of the following core components:
Dart Language
Flutter apps are written in Dart, a modern object-oriented language. It supports both ahead-of-time (AOT) and just-in-time (JIT) compilation for high performance and rapid development.

Flutter Engine
The Flutter engine is written in C++ and uses Google’s Skia graphics library to render UI components. It provides low-level rendering support and handles:
- Input
- Text layout
- GPU acceleration
- Plugins and platform channels
Foundation Library
This is the base of the Flutter SDK, written in Dart. It includes:
- Essential classes and functions
- APIs to communicate with the engine
- Tools to develop apps using Flutter’s architecture
Custom Widgets
Flutter uses a layered approach to UI. Developers can combine simple widgets to build complex layouts. Flutter supports:
- Material Design components for Android
- Cupertino-style components for iOS
In our own projects, we’ve leveraged custom widgets for scalable UI and utilized the foundation library to directly draw text, shapes, and images—enhancing both design and performance.
Stateful Hot Reload
This powerful feature lets developers instantly reflect UI changes by injecting updated code into the running Dart VM, avoiding full app restarts.
Hot reload enables faster bug fixes, improved UI iterations, and quicker feedback loops.
Final Thoughts
Flutter has revolutionized how businesses approach mobile app development. It allows teams to build native-like apps at a lower cost while delivering a seamless user experience across platforms.
Whether you’re launching a startup MVP or transforming your enterprise mobile strategy, Flutter is a robust, future-proof solution. With its multi-platform capabilities, strong community, and backing by Google, Flutter continues to lead the way in cross-platform mobile development.
