Main reason I'm replying is you've misspelled Fuchsia as Fuschia and to ramble a bit, maybe this was on purpose and if so that's ok.

Some more ramblings -
My understanding with Fuchsia and programming languages,is they ditched Google's GoLang for Rust, they don't like GCs, but they're keeping Flutter due developer productivity, dart's hotreload feature, etc.
If Fuchsia ends up in the phone space, they would want it to run android apps,
work is going on with starnic for running unmodified linux apps.
Also I watched some of the Fosdem ubuntu stand talks, the Flutter desktop talk
had an interesting demo, with the Ubuntu person saying all new ubuntu apps are to be Flutter apps.
Tidbit - The ubuntu team is working on Full Multi-window for Flutter desktop for windows, mac and linux.
Security
"Zircon is a capability-based, object-oriented kernel"
"The Zircon system fully isolates processes by default, and must explicitly grant capabilities and resources. Fuchsia passes capabilities and resources by handles rather than name, which leads to a system that only grants software access to what it needs."
My understanding with toit vm you have can have multiple programmes running and if one crashes, the others continues. The vm, etc, allows live update and or to deploy something new.
If you're interested in hearing Kasper talk about toit, he did a long livestream the other day, the toit bit is at the 1hr 34min mark.

Seems with Flutter being open, the growth of flutter outside of mobile was started by others, with it's being picked up by other teams within google and outside of google.
Teams from Sony, Toyota and Samsung(Tizen) are giving flutter a go on their own.
Also the ubuntu guys are active committers to progress flutter desktop.
As regards Javascript, that's what they started with, they looked at other languages and gave dart a go, it gave them faster startup and the dart team offered them stateful hot reload.
Anyway working in the chrome space, they prob didn't know that Kotlin existed pre 2015 and prob would have gone with Python if could.
tidbit - there is early support to build linux flutter apps on the raspberry pi. Would be good if android team offered arm builds of their tools, then it would be possible to build for android on the pi.
"Flutter is committed to supporting developers in making their apps more accessible, and includes first-class framework support for accessibility in addition to that provided by the underlying operating system, including:
Large fonts
Render text widgets with user-specified font sizes
Screen readers
Communicate spoken feedback about UI contents
Sufficient contrast
Render widgets with colors that have sufficient contrast"
>But doesn't it seem reasonable to use TypeScript for flutter now?
Flutter started as an experiment from chrome team, so their first language was JavaScript, when they move to dart they decided to write the whole framework layer in dart, the engine is in C/C++, so it seems there is no going back to a JS world.
With the Dart, they got a VM, GC and other tools and a language team that could grow Dart to suit flutter.
They also got stateful hotreload, a Dart idea, which was something that the Flutter team didn't know they wanted.
Lars gave a talk last year and said the intent was to put dart vm in chrome, then the whole mobile thing happen and there was no room for extra stuff in chrome.

Flutter on studio 4 is working fine for me onlinux, just had to enable and upgrade the flutter and dart plugins, only tried on flutter master channel with linux and web devices.
Yeah Flutter's main focus is mobile, they are working on Desktop Flutter, you can try it out on the master channel.
It looks like they are making progress, Chris Sells, a Flutter PM, tweeted
"While things have been delayed on the desktop side for Flutter due to the current crisis, the team has been working hard to bring both Windows and Linux support to alpha. I think you're going to be happy about what you see."

If you just want to try out flutter, I wonder if you can avoid the android stuff by just running on ios and when they are ready the desktop and the web.
They certainly did find a new purpose for Dart outside of it being used in parts of their Ads platform, but
Flutter, when is was the chrome experiment called sky, first started out using Javascript.
The chrome guys decided to move on and look at several language before going with Dart, Swift may have been an option, if it was opensource at the time.
Seems a reason for Dart's failure in the web space was mobile.
Lar gave a talk last year about his and Kasper iot startup https://www.toitware.com/ he mentions why dart didn't make it into chrome, saying "then the whole mobile shift happen and there was no room for extra stuff in chrome"
