I can take this on, but from my testing on the adwaita test app, this is just a new window, not a dialog which cant leave the app, so I'm not sure if we should implement it as a dialog or not

[prateekmedia]

Yes but implementing it as a Window would not be a easy task may need to use multi window packages from pub.dev

[simrat39]

Yeah ill just stick to a normal dialog, don't think anyone wants to move it out of the main window anyways

[simrat39]

Looks like we already have something similar https://github.com/gtk-flutter/libadwaita/blob/main/lib/src/widgets/adw/about_window.dart, or is there any difference?

[prateekmedia]

We already have but it's not that feature rich, as It was create before the about window was merged.

Like we don't have credits, legal or acknowledgement section as shown in above Gnome Builder pics.

Although we don't need all sub categories but we need some kind of way for developers to add it

Also current about dialog doesn't have animation when navigating inside the dialog

[simrat39]

Ok sounds good, so I just extend that widget then right

[prateekmedia]

Yes that would work

[simrat39]

Got this much done, will continue working on it tomorrow

[prateekmedia]

Wow, looks great. Animation look cool.
