Are you looking to supercharge your Flutter applications by embedding native Windows components? Look no further! This guide will take you through the process of utilizing the flutter_native_view plugin to embed native windows directly into your Flutter application.

What is flutter_native_view?

flutter_native_view is a Flutter plugin that allows you to embed native Windows (HWND) components directly into your Flutter window. This capability enhances your application’s performance by leveraging native APIs without the overhead of textures or pixel buffer copying. Ideal for embedding third-party windows like video outputs or web views, this plugin provides flexibility and programmatic control.

Getting Started

To set up flutter_native_view, you first need to clone the repository. Here’s how you can do it:

• Clone the repository:

git clone https://github.com/alexmercerind/flutter_native_view.git

• Navigate into the project directory:

cd flutter_native_view

Modifying main.cpp File

Now, you need to modify the windows/runnermain.cpp file. Insert the following lines to include and initialize the plugin:

#include flutter/dart_project.h  
#include flutter/flutter_view_controller.h  
#include windows.h  
#include flutter_native_view/flutter_native_view_plugin.h  
#include flutter/window.h   
#include utils.h  

window.SetQuitOnClose(true);  
flutternativeview::NativeViewContainer::GetInstance()->Create();  

::MSG msg;  
while (::GetMessage(msg, nullptr, 0, 0)) {  
    ::TranslateMessage(msg);  
    ::DispatchMessage(msg);  
}

Initializing the Plugin in Your App

Use the following code to ensure that the plugin is properly initialized within your Flutter application:

void main() async {  
  WidgetsFlutterBinding.ensureInitialized();  
  await FlutterNativeView.ensureInitialized();  
  runApp(const MyApp());  
}

Creating Native Windows

Next, let’s create a controller and utilize the NativeView to render a window:

class _MyAppState extends State {
  final controller = NativeViewController(
    handle: FindWindow(nullptr, VLC Media Player.toNativeUtf16()),
    hitTestBehavior: HitTestBehavior.translucent,
  );
  
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: Padding(
            padding: const EdgeInsets.all(24.0),
            child: Stack(
              children: [
                LayoutBuilder(
                  builder: (context, constraints) => NativeView(
                    controller: controller,
                    width: constraints.maxWidth,
                    height: constraints.maxHeight,
                  ),
                ),
                Padding(
                  padding: const EdgeInsets.all(16.0),
                  child: FloatingActionButton(
                    onPressed: () {},
                    child: const Icon(Icons.edit),
                  ),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }
}

Understanding the Code with an Analogy

Think of building your Flutter application as constructing a house. The flutter_native_view plugin is akin to installing an advanced security system. The main.cpp modifications serve as the foundation work, ensuring the systems are well integrated into your house’s infrastructure.

The initialization of the plugin in the main function is like connecting the wiring of your security system to the main power supply—it gets everything up and running. Finally, when you create a NativeView, you are essentially installing that security system, allowing it to monitor specific areas of your house (or application) with complete control and flexibility.

Troubleshooting

If you encounter issues while embedding native views, consider these troubleshooting tips:

• Ensure that you have correctly set up the main.cpp file as detailed in the setup section.
• Verify that the HWND you are passing to the NativeViewController is valid and properly initialized.
• Make sure that you are running a compatible version of Windows (Windows 10 or higher).
• Consult the documentation for any overlooked installation steps.
