Clone the source code and compile by yourself. I tested on my Ubuntu Arm64 running in paralle desktop.

npm run build:bridge:linux:release

Yes! I have build as your introdution.
But when I run the demo, There is error as follow:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Null check operator used on a null value
#0 WebFController.preload (package:webf/src/launcher/controller.dart:1308:34)

The error show that "view.document.documentElement" in function "WebFController.preload" is null. It seems did not create "documentElement" when exec "initDocument".
And I found that the function "readNativeUICommandMemory" in file "lib/src/bridge/to_native.dart" only return eight commands. That may be the native function "getUICommandItems" run unusually, but I do not why. The operation status is as follows：

Check the requirement and guides on https://github.com/openwebf/webf/blob/main/.github/CONTRIBUTING.md

Test passed on my machine, make sure your binary compiled success before you start build your flutter apps.

Or check the example app I built on your devices:
