Add support for Flutter

[emersion]

Look at pubspec.lock and generate Flatpack builder sources from it.

[hfiguiere]

there is no flutter sdk, so there is no point having anything here.

There is no Electron SDK either.

It should be possible to build a Flutter SDK extension.

There is the electron base app which is the form the SDK has taken.

As for Flutter, well, pull request welcome. It currently has fundamental flow that prevent it from being done.

I was playing around with flatpak-pub-generator once a long time ago but never got too far into. That would honestly be the easy part though... Flutter's tools also assume they can download various libraries that would definitely have to be saved in advance. Not sure if that should go in the same tool or not, but it would definitely be the main "tricky" part of this.

There is the electron base app which is the form the SDK has taken.

It doesn't actually have Electron, so not really anything close to an actual SDK extension. We also have cpan & rubygems generators, but neither of those are in the runtime, only SDK...

@hfiguiere what do you mean by a flutter flaw ?

[hfiguiere]

it can't run from a read-only location.

[emersion]

Running from a read-only location should work after running flutter precache.

[hfiguiere]

but if you expect this to be run in the SDK build, and it is designed to pull stuff out of the network, then it won't work.

Build is 100% offline.

Can't it be downloaded from the Google website?

That's what I have created. It's a part of flatpak-flutter, a tool that assists Flutter developers in the creation of a Flatpak manifest that builds the app from source while 100% offline.

The tool: https://github.com/TheAppgineer/flatpak-flutter

My published Flutter app: https://github.com/flathub/com.theappgineer.community_remote

Be aware that this project is very fresh. If any Flutter developer wants to give this a try and provide feedback, that would be appreciated (please use the projects GitHub for this).
