javafx-gradle-plugin VS Introducing .NET Multi-platform App UI (MAUI)

One, I don't understand Java environments really well. All I have done so far is create some GUI applications using JavaFX. Wish I could share my code, but unfortunately, its part of my assignments and can't be open-sourced. Second, the instructions I found in the Contributing docs were bare-minimum, and kinda hard to follow for a beginner. An experienced Java developer would get them really quickly, no doubt about that.

JavaFX (an open source, next generation client application platform for desktop, mobile and embedded systems) has many useful out the box UI controls to build modern interactive desktop apps. These include buttons, checkboxes, list views, labels etc, that can be configured and styled in countless ways. I’ve using them for many years at work building mapping apps!

As I'm typing this, I'm realizing that the 4 part webinar actually sets up a lot of it. By this point, you should have installed: your IDE (I used intellliJ), the Java SDK, downloaded the JavaFX file here(that you'll manually add into your project structure), and the MySQL connector J file.

JavaFX works well with Kotlin if you're looking for an imperative toolkit. Just add this plugin in your build.gradle to import it.

You could also download the JavaFX modules separately from https://openjfx.io/

I am migrating XF app into MAUI and writing a simple Navigation framework because Prism doesn't work well and I didn't use anything advanced anyway. So, I am surfing the code of MAUI to intercept all the back buttons, etc. I haven't found a single mention of apis related to predictive back "RegisterOnBackInvokedCallback", "OnBackInvokedDispatcher", "OnBackPressedDispatcher", "AddCallback", "android:enableOnBackInvokedCallback" Also I don't see any issue on github that would say "Support Android Predictive back". Only one kinda related https://github.com/dotnet/maui/issues/8680

Below issue is still reproducing in Maui .net7.0 version also. #10163

I do share your skepticism of Microsoft, but it looks like the economics and cash flow dynamics have changed drastically after the advent of the cloud.

Microsoft is more focused on getting developers onto its ecosystem and help them with open source projects with the hope that they will use its Azure cloud services and bring in the money.

My skepticism is a bit relaxed now and I have no qualms using .NET.

I hope I am not wrong.

It's a bit of a hit and miss as of today. CLI, back-end and natively compiled libraries (think dll/so/dylib or even .lib/.a - you can statically link NAOT binaries into other "unmanaged" code) work best, GUI - requires more work.

Avalonia[0] and MAUI[1] have known working templates with it, but YMMV.

I think the fundamental issue is that desktop Linux is way too fragmented. Not only just GTK2/3 and Qt but you have GNOME, KDE, XFCE, Cinnamon and then you have X11, Xorg, Wayland...

To be honest, all those craps are why desktop Linux never took off. I'm very safe to say MAUI for Linux will eventually renders components off its own using framebuffer and hardware acceleration APIs such as OpenGL or Vulkan just because of the market fragmentations...

If desktop Linux truly wants to get the attention, it will need to unify. Fixing dependency hell using Flatpak is the right direction.

There is an existing old fork of MAUI for Linux that uses GTK: https://github.com/jsuarezruiz/maui-linux

First I came across this Github issue: https://github.com/dotnet/maui/issues/9687 - According to this issue, this is a known bug for MAUI iOS, but it works OK for MAUI Android. As I said, I target Android only and I have the exact same issue. It's apparantly fixed with some of the latest versions for MAUI but the problem still occurs to me even with MAUI version:

I saw this and tried to imitate (ofc my lack of experience wouldn't allow me to do it in the exact way). Already found some documentation that allowed to understand better. Thanks for the insigh.

I implemented the Auth controller following this sample code from Microsoft.
