In today's increasingly mature mobile internet era, cross-platform development has become a mainstream trend. How can a single codebase be used to simultaneously build Android, iOS, Windows, Linux, and even Web applications? This is precisely the significance of Flutter's creation.

Flutter is a cross-platform UI framework led and continuously maintained by Google, written in the Dart language. Since its release, Flutter has rapidly grown into one of the most popular cross-platform development frameworks in the world.

1.Core Features

  1. True cross-platform:

    1. Android
    2. iOS
    3. Windows
    4. Linux
    5. MacOS
    6. Web
    7. Embedded devices One codebase, runs on multiple platforms, with highly consistent UI presentation.

  2. Self-drawn engine, highly consistent UI presentation Flutter does not rely on native system controls; instead, it draws the interface through its own rendering engine (Skia). Advantages:

    1. Unaffected by system version differences
    2. Highly unified UI presentation
    3. Can achieve extremely smooth animation effects
    4. Suitable for highly customized interfaces

  3. High performance close to native, using the following technologies:

    1. AOT compilation (Ahead-of-Time)
    2. Direct rendering to Canvas
    3. Does not rely on bridge communication (unlike React Native) Achieves performance close to native applications. For complex animations, large lists, and real-time interaction scenarios, it still performs stably.

  4. Hot Reload During development, when code is modified, the interface refreshes almost instantly.

    1. Extremely high UI adjustment efficiency
    2. Very suitable for rapid iteration
    3. Low learning cost, quick to get started

  5. Advantages of the Dart language

    1. Syntax is close to C / C++ / Java
    2. Supports object-oriented programming
    3. Supports asynchronous programming (async / await)
    4. Fast compilation speed Those who read my blog and knowledge base all have a C/C++ or embedded development background, so learning Dart will be very easy.

2.Summary of Flutter's Advantages

✅ One codebase, runs on multiple platforms ✅ Excellent performance, close to native ✅ Strong UI consistency ✅ Extremely powerful animation capabilities ✅ Active community, mature ecosystem ✅ Backed by Google for long-term support

3.Flutter Application Scenarios

Flutter is not just for mobile apps; its range of applications is very broad:

📱 Mobile App Development

E-commerce, social, and utility apps

💻 Desktop Application

Management backend, host computer software, tool software

🌐 Web App

Backend management system, corporate official website

🤖 Embedded UI

In-vehicle systems, IoT device screen interfaces

For embedded or ROS developers, Flutter is well suited as a cross-platform host computer solution.

4.Industry Trends and Corporate Practices

Flutter is not just a “toy for individual developers.”

🌍 Google Official Support

Flutter is one of the cross-platform technologies that Google officially focuses on and invests in, and it is used in multiple internal products.

📱 Xiaomi is going all in on Flutter

In recent years, Xiaomi has extensively adopted the Flutter technology stack in the reconstruction of its mobile, automotive systems, and applications, and has gradually made it one of its core UI solutions.

This means:

Flutter has entered large-scale commercial product systems

No longer used only by startup teams

possesses long-term technical vitality

5.Who is this tutorial for?

  1. Developers who want to build cross-platform apps
  2. Embedded / host computer developers
  3. Programmers with a C / C++ / Java background
  4. Engineers who want to cover multiple platforms with one technology stack.

6.Why learn Flutter now?

Cross-platform is no longer a trend, but a reality. The future form of software:

  1. Mobile + desktop + Web + IoT convergence
  2. Multi-device collaboration
  3. Unified UI technology stack
  4. Flutter is precisely the product of this era.
