Deferred route on web

[jaumard]

I read that best practice for flutter web is to use deferred import to optimize loading time.

I was wondering if there is any exemple of how it work with go_router, I was expecting a GoDeferredRoute

Can you point me at that guidance?

[jaumard]

Sure!
Here is a medium article that talk about this https://medium.com/flutter/optimizing-performance-in-flutter-web-apps-with-tree-shaking-and-deferred-loading-535fbe3cd674

Official docs mention it here https://flutter.dev/docs/perf/deferred-components but not dedicated to flutter web.

Would be awesome to have GODeferredRoute that take care of loading the deferred component to improve loading time.

I'm open to a PR for sure.

Although in thinking about it more, if your pages are deferred types, then it should just work, right?

[jaumard]

Deferred types mean that before you can use it you need to load it, so it's a async process. So it need to be taking care in some way or it doesn't work, to be honest I didn't make any testing about this yet. And I just start building for web so I was searching for some examples ^^

To load the page types asynchronously, I'd use a pattern like the one described here: https://pub.dev/packages/go_router#async-data
