Add Flutter template

[ndonkoHenri]

Can we please have the flutter template files here too?

Hi there! We're working on it! Unfortunately the Flutter template is the only one that's a bit more involved than just a simple template. We're working on bringing the Flutter environment 100% onto our templating system, which is taking some time.

@romannurik Flutter, please check this link , I found most of part useless,

[romannurik]

@mg3994 We have a number of alternative/secondary approaches to spinning up Flutter workspaces that are unofficial/experimental (that's one of them) ... but the default "new Flutter app" experience on IDX isn't currently replicable purely via custom templates unfortunately.

The flutter template I created can get pretty close to the environment with the default flutter template but still not 100%.

[romannurik]

yeah, my understanding also is the default flutter template is hyper-optimized for startup performance, using mechanisms unavailable to other templates at the moment.

[rodydavis]

Yep but if speed is not the concern then the template I shared will still have flutter fully working with the previews on Android and web 👍🏼

I saw that nixpkg flutter package is not up to date, interesting how this is solved in idx, probably some custom nix flake?

[rodydavis]

I only use the flutter nix to bootstrap the files.

Also the clarify the flutter template I create is just as fast running and is still super quick opening.

It adds a lot of the flutter create commands to the template instead of caching the flutter counter app only.
