Hi @jtkeyva, thanks for the feature request! Yup, it would be a nice feature to have, for sure. Do you have any ideas on how to implement it or how you see the implementation of it? As a workaround, obviously, you can add all the static content as assets to your app so that they will be bundled together with the slides.

hi @mkobuolys well i have not dug into your code so much quite yet but https://pub.dev/packages/advstory does a tremendous job. i see a full other use case for your package to be also a media player, but not sure what your goal or intent is for it.

basically you can create custom "content types" templates and for each slide simply choose a type and it will be formatted...similar to what you do. there is just a lot of overlap and similarity that to me might make sense to merge into a general presentation package.

@jtkeyva The package you provided is basically a page view that could be added to any app. Since it's a page view, it's possible to preload components in the background (basically render them) and show them whenever needed. However, flutter_deck is built in a different view. It's like any other web app, where each slide is a stand-alone page with a custom route. Thus, it's more tricky to preload or cache its content - do not say it's impossible, but much much more tricky.

So just looking at this from the architecture point of view, it's really not that similar as you could think.

[jtkeyva]

got it thank you. i'll dig around a bit more to see how you've built it :)

hi @mkobuolys i've been digging in a bit and have multiple decks within a pageview which works ok. i have custom routes per deck which is nice. buuuut.... can this be handled dynamically or do the routes need to be set at build time? and could i pop this in my existing app which also uses go_router and have something like:
/home
/settings
/decks
/decks/deck1/slide1
/decks/deck1/slide2
etc?

[jtkeyva]

i sorta got it working but the routes are ephemeral. like i can link to it but it forgets about it if i use the back/forward browser buttons or a simple refresh and i get a GoException. also, i cannot deep link to it. there are 2 instance of go router and they seem to be conflicting. this is likely the fundamental problem when trying to nest the app within an app. any ideas how to do this?

[mkobuolys]

Hey, it's hard to say exactly what the problem is. I have never injected another go_router app inside the flutter_deck, only the simple push/pop one. Could you share the code of what you are doing and what you are trying to achieve? When I have time, I can dig a bit more and check what's possible at the moment.
