rCOMMea3f91b287d3: [native] Display both photos and videos in the media gallery on native

Summary

Now that the responders and endpoints are set up, we need to populate the FlatList with real data from the database. This means we need to get the data and use it as the data prop in the FlatList.

Previously, the component memoized an empty array mediaInfos to prevent the FlatList from re-rendering each time ThreadSettingsMediaGallery re-rendered, since otherwise the array would have a new reference. Now, with useState, the reference to mediaInfos should persist across re-renders and mediaInfos shouldn't change until we fetch the media. This will be important for when we incorporate a full screen media gallery and fetch more media as the user scrolls to populate mediaInfos.

Depends on D6587

Test Plan

Confirmed on both iOS and Android that the media loads in the thread settings. The videos are linked below.

63	Please avoid ternary in JSX like this

Remove ternary statement. Introduced renderMediaContainer to avoid copying code

Harbormaster completed remote builds in B16282: Diff 22279.Feb 8 2023, 8:33 AM

Remove ternary but remove renderMediaContainer actually, since it'll make it harder to potentially display timestamps on videos (I can bring it back when adding timestamps if it still reduces similar code)

Rebase on the stack to have the updated stylings to match the design

82–93 ↗	(On Diff #22430)	Shouldn't we memoize `source` props?

82–93 ↗	(On Diff #22430)	Again @rohan really want to emphasize that you need to get up to speed on memoization... otherwise it's going to continue causing repeated churn for you on every diff, and it's going to cause all of your reviewers to have to spend a lot more time on your diffs

native/chat/settings/thread-settings-media-gallery.react.js
82–93 ↗	(On Diff #22430)	Sorry... I considered it but looked through the codebase and thought (mistakenly) that I saw it wasn't a pattern to do so. I can make a memoized array that holds a uri for each index and use that array[index] in the `source` prop.

native/chat/settings/thread-settings-media-gallery.react.js
82–93 ↗	(On Diff #22430)	Ah yeah we're not always perfect in the codebase today... Generally best to follow "first principles" on memoization and just ask yourself – will this lead to more render cycles if it's recomputed? If yes, always memoize (unless you'd be memoizing `children` prop or JSX, which is usually too messy to be worth it)

Memoize source props so we only recompute when mediaInfos changes

native/chat/settings/thread-settings-media-gallery.react.js
82–93 ↗	(On Diff #22430)	Got it, I'll be sure not to take the existing code as the only source of truth when making decisions

Looking better on memoization!

native/chat/settings/thread-settings-media-gallery.react.js
85 ↗	(On Diff #22627)	You're introducing the second direct usage of this in our codebase. That should give you pause... why don't we use this component directly in other places? You should think about whether there's another component in our codebase that you should be using. It's generally best to reuse internal components then to create new codepaths to external libraries
96 ↗	(On Diff #22627)	Shouldn't we just be showing the thumbnail?

Wrote a comment in D6485, but in theory once that is done, we'd have a more "proper" Media item here that we can construct into a MediaInfo (by adding the index) and passing that as a prop into something like Multimedia. This allows us 1. not to display the videos on render but instead the thumbnails, and 2. Multimedia renders RemoteImage and that renders FastImage (I'll double check this once I get back to this diff though since I looked quickly)

Render Multimedia component to re-use internal components (this component already handles displaying the thumbnail for videos)

Harbormaster completed remote builds in B16590: Diff 22696.Feb 17 2023, 4:13 PM

Remove corners from MediaInfo here since we need to pass in a MediaInfo into Multimedia. Ran flow with no errors

Looks great, just a question

native/chat/settings/thread-settings-media-gallery.react.js
90 ↗	(On Diff #22697)	Can you explain why you added `GestureTouchableOpacity` here?

native/chat/settings/thread-settings-media-gallery.react.js
90 ↗	(On Diff #22697)	I didn't have a particularly strong reason, looking into `Multimedia` I saw the only other instance of it being rendered within some kind of touchable opacity was within the `GestureTouchableOpacity` here, originally introduced a while back. I know the same problem doesn't occur here but I decided to keep consistent. Happy to switch back to the react-native `TouchableOpacity` though

native/chat/settings/thread-settings-media-gallery.react.js
90 ↗	(On Diff #22697)	Not asking about `GestureTouchableOpacity` vs `TouchableOpacity` I would've introduced the `GestureTouchableOpacity` in the same place where you set `onPress`, so it's clear what it's for
