hydro-sdk VS Introducing .NET Multi-platform App UI (MAUI)

There is already a project trying to bring Typescript into Flutter, but its on early development: https://github.com/hydro-sdk/hydro-sdk This will also probably create many extra pains for developers since existing Dart packages would have to be wrapped.

It's probably vastly more trouble than it's worth, but you could technically write the package in Typescript and use Hydro SDK to compile it to Lua bytecode that can run on the Dart VM with Flutter bindings, then distribute that bytecode with a package that wraps the Hydro API.

As an open source author, I've been thinking about some general and domain specific optimizations https://github.com/hydro-sdk/hydro-sdk/issues/797 I'd love to chat if OP has time.

In terms of interoperability, the short answer is mostly-yes. Any Dart code can be made to interoperate with code written using Hydro. Taking an existing Dart package and making it useable from Hydro is automated. The tooling isn't quite ready for prime time (nor is the entire SDK) https://github.com/hydro-sdk/hydro-sdk/tree/master/lib/swid

Hydro-SDK has a small Dart-like language built into it to support binding generation (https://github.com/hydro-sdk/hydro-sdk/tree/master/lib/swid/frontend/swidi).

The analyzer API is enormous. I've had a lot of success using the analyzer API, but abstracting over it with my own ASTs that can be manipulated and transformed (https://github.com/hydro-sdk/hydro-sdk/tree/master/lib/swid) and using code builder (https://github.com/dart-lang/code_builder) to emit Dart code.

I've been having a lot of fun writing a compiler in Dart (in a pure functional style, with pattern matching and sum types!) over here https://github.com/hydro-sdk/hydro-sdk/tree/master/lib/swid

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.
