Packages for Windows, macOS, and Linux Flutter supports desktop platforms. screentextextractor - This plugin allows Flutter desktop apps to extract text from screen. have done everything correctly, your package will be publicly available on Pub. screenretriever - This plugin allows Flutter desktop apps to Retrieve information about screen size, displays, cursor position, etc. To do this, we’ll use Event Channels, let’s open lib/windows_dark_mode. screencapturer - This plugin allows Flutter desktop apps to capture screenshots. Let’s start by cloning this Repository and opening the project in our IDE.Īs we know, using a Method Channel in Flutter is like calling a remote API, but now we need to subscribe to a Stream. Implementation, Flutter Sideīeing in a Flutter App, things are a little different. When a WM_SETTINGCHANGE message is intercepted, if lParam points to “ImmersiveColorSet”` Unicode String, the OS is signaling that something has changed in the current UI Theme.
FLUTTER DESKTOP WINDOWS
This is our new handler that will be called every time a Windows WM_ message “arrives”: LRESULT CALLBACK MyWndProc(HWND hWnd, UINT iMessage, WPARAM wParam, LPARAM lParam) Suppose we want our App to receive an event every time that the user switches Dark Mode on or off in Windows.ĭoing this in a Win32 App, using C++ or other “native” languages, seems straightforward: we have to register an handler to listen for Windows WM_ events that our App receives: HWND handle = GetActiveWindow() oldProc = reinterpret_cast(GetWindowLongPtr(handle, GWLP_WNDPROC)) SetWindowLongPtr(handle, GWLP_WNDPROC, (LONG_PTR)MyWndProc) If you are already experienced in writing Plugins using Platform Channels, jump to the next paragraph, if not, you can read the previous story: To learn how it can be made we will implement an Event Channel that can make these events available in our Dart code. Flutter doesn’t have a ready-made interface for doing this.
However, as told before, designing our shiny new Windows App in Flutter sometimes there could be something that we miss.įor example, we could need that our App should react to Windows system-wide events, and change its behavior accordingly.
Thanks to the work of several enthusiastic people, a lot of packages on pub.dev support Windows development, and the list is growing. Ok, this wasn’t news, Flutter compiled applications for Windows before, why is it so important now? The answer is a simple word: “stable”, cause now Google declared it is, we can decide to invest more of our time and resources in developing Apps for Windows using this fantastic tool.

And honestly speaking, I thought I’ll be spending at least 2 months to release the first version of it.Īfter spending 2 weeks working around 2 hours/night on this project, I ended up with something that actually worth publishing. In this codelab, youll build a desktop application featuring a GitHub GraphQL API integration using the Flutter SDK. But, it was the best way to discover the advantages ✅ and the limitation ⚠️️ of using Flutter web in a web project. įrankly speaking, The project itself isn’t something useful 🤷🏻♂️ it’s not solving a problem, and probably it’s not my next billion-dollar idea. Flutter will win the Desktop because today, in very early alpha/dev release, it demonstrates a surprising level of competence, even when compared to solutions that have been in this space for a. That pushed me to try something challenging, creating a Desktop GUI using flutter web as my new portfolio website 😎.
But getting back to it two weeks ago, I was surprised about the number of plugins currently supporting WEB. I wasn’t really expecting a lot from the stable release of Flutter Web since I’ve already tried the Beta, and there wasn’t enough support for most plugins. This doesn’t only mean that I can finally stop writing HTML and CSS code, but also that I can now have one app that can run on almost all popular platforms 🤯. As part of Flutter 2, Flutter has announced that Flutter’s web support has hit the stable milestone.
