Feature: reduced motion mode

[aelnona]

Hi! Thanks so much for your work on the app, it's been a real joy to use :)

Only thing is, I keep animations on my phone turned off in the accessibility settings, as the motion gives me nausea - but it seems Glider does not follow these for every animation (understandably; I suppose it's not something most users need or care about ofc).

Could there perhaps be some setting to toggle all animations on/off?

I've looked into this a bit. It turns out the system setting is exposed as disableAnimations in Flutter, but the framework itself doesn't actually use that value for anything.

I might add code that respects that system accessibility setting and limits animations when turned on.

The good news is that the Flutter framework does use the mentioned field, for instance to make page transitions instant. I've added code that uses it to disable the app's custom animations as well (989be94).

The bad news is that... it doesn't actually work in practice. At least not on fairly recent Android versions. Flutter always reports the disable animations accessibility setting as being turned off. This appears to be a framework bug: flutter/flutter#130976.

I would prefer this to be fixed by the Flutter team, but there is always the option of adding a separate setting for it in the app.
