flutter-desktop-embedding | Experimental plugins for Flutter for Desktop | Dektop Application library

The actual .exe is under build\windows\runner\Release. Good luck!

There is a cursor property on MouseRegion, which controls what cursor is shown when the pointer is in the region. For instance:

Those methods are currently implemented only for macOS. You can subscribe to this issue for updates on Windows and Linux.

flutter_test is not a regular package that you can override the version for - it is a part of the Flutter SDK.

What you can do however is override the version of collection such that both flutter_test and image_size_getter use the same version and no longer conflict.

Try this:

If you flutter build or flutter run a desktop project, you're already building a .exe; that's what's being launched by flutter run. You can find it in the build directory of the project (e.g., build\windows\x64\Debug\Runner\Flutter Desktop Example.exe for the FDE example app).

This happens because you are calling dart_image.decodeImage(bytes) 20 times at once on the main isolate, which will keep the CPU core assigned to the main isolate 100% busy with decoding the images until they are all completed. Because of this, despite correctly calling setState, the CPU is too busy to be able to compute the layout before passing it on to the GPU to draw it, so your app is completely frozen.

To prevent this, you will want to delegate the hard work to other isolates. Flutter provides the compute function which will spawn a new isolate, run the provided function within it using the provided parameters, and return a Future with the result. For your use case it would look like this:

How can i improve performance at startup ?

Flutter for Windows currently only supports debug builds, which among other things means that it's using JIT compilation, not AOT as a release build of a Flutter application would. Slower startup time is one of the downsides of JIT.

Is it possible to show the window when content is ready to display ?

There is currently no callback hook for when the first frame is drawn, so this would be difficult, if not impossible, to do accurately.

Or shall i use a splashscreen (I don't even know if this is possible with windows, and if so how) ?

There is no support for splashscreens in Flutter's Windows embedding.

You can't get references to any GLFW objects through that API. This is by design because, as the comment you quoted says, you can't have multiple copies of GLFW within the same process. GLFW is statically linked into the Linux Flutter embedding, so you can't use GLFW in the runner or a plugin.

Implementing a video player should be done using the texture APIs, which will be added for GLFW in this PR.

If you are actually trying to build a plugin, per the title of your question, you don't put your code anywhere in that directory; instead you would create a plugin and put the code there. Being separate from the application is what makes it a plugin.

If you just mean you want to add MethodChannel-based code directly to your native app, you can put the code wherever you like in that directory (I would recommend a new file so that it's not intermixed with the still-volatile basic Runner code that you will need to replace every time you update Flutter). As long as you don't break core assumptions like the name of the project or build settings used by Flutter the project is yours to do what you like with, just as with template-created Flutter projects targeting mobile platforms. You would just need to register it in main. Right next to the line calling the generated plugin registrant would be a good place for that.
