Memory problems for long ListViews with Image from Network?
Hi, after days of searching for solutions, it seems that this is a known problem so I'd like to ask here in hopes that anyone has a bandage solution.Here's my situation:I have a ListView.builder populated with ListTiles, each of which has to display one single image that is loaded from a url. (It's a list of hotels). This starts to become a problem when run on older devices with smaller RAM, such as an iphone 6+ with 1GB ram. It can load close to 150 or so images, anymore than that the app crashes due to memory issues. I have tracked with Dart Dev Tools and it seems to reach above 1 GB in memory at times when my app requires a list that loads up to 500+ images.This issue is holding me from releasing the iOS version to the customers. I'm relatively new to developing but I've tried my best to scour for a solution and I can't seem to find one. What I'm looking to achieve is basically what Picasso or Glide does for android, where they seem to only load the necessary images without compromising much in terms of UX.Things I've tried:Cached Network Image, Advanced Network Image as well as flutter's own Image Network / NetworkImage.https://stackoverflow.com/questions/59730589/any-lightweight-flutter-network-image-plugin-for-long-lists-up-to-500-image-uSome of the things I've found:https://github.com/flutter/flutter/issues/32156https://github.com/flutter/flutter/issues/32143https://github.com/flutter/flutter/issues/44510https://github.com/flutter/flutter/pull/48536​Not sure if this is the right place to ask but I'm gonna try anyway. Thank you for any help/clue you may provide. Looking forward to learning new things.

Looping a three part Rive/Flare animation
I'm still working on my Flutter Clock submission, but have ran into a lack of documentation on how I should go about "looping" the animation using Flutter and Rive. My animation essentially has three parts: a beginning (only played once) a middle (played as a loop) and an end (also played only once). I was wondering if there were any examples that better show how I should code these animations to run in this order with n number of loops (or if there was a way I should create the animations in Rive to better handle these state changes)? I assume that I'll need to retrieve parameters like the current length of the animations that are played once, but I was just curious if there was a method that fires after the Rive controller has finished the animation.

web named input field?
I'm trying to create a login form that plays nice with the existing credentials management ecosystem. I believe they mostly key off the input field names. Is there a way to emit input elements that have the html name attribute set using TextField or TextFormField ?

Properties in ThemeData and component properties they affect
I feel like I've been searching for this for too long:What do each of the properties in ThemeData affect? If I want to change something, say the text style of a particular widget, how do I know which text style to change in ThemeData?Take this example: I wanted to have a specific text style for my AppBar (top app bar). I'm not sure if I'm not going about this correctly, but it took me a while to realize that it is textTheme.title, a property of AppBarTheme() that changes the app bar text style.Also, for buttons, for the textTheme, I could put ButtonTextTheme.primary, or ButtonTextTheme.secondary. What exactly are the differences in these?Same issue with colors. Is there a list of what each property (primary, accent, focus, indicator, highlight color) affect in your UI?I know I could dig into the source code of each widget and check for myself, but I feel that there should be a list. I made an issue about this, it seems that some progress is being made (#36624)Relevant documentation: https://api.flutter.dev/flutter/material/ThemeData-class.htmlThis youtube video Material theming in Flutter is recent, and there's one commenter who has the same problem as me:What I really want is that ALL properties in ThemeData (including it's nested Themes and a colorScheme) would have a full list of components they affect somewhere well documented. AND the full list of all components in Flutter with their corresponding ThemeData properties which defines their color/style. For now I have to Google on how to change color for "foo" component and go through a bunch of StackOverflow questions before I find the right one. It's all should be in docs in one place. For example, how do I know where to change the color of the text on the textfield contextual popup menu (the one that has CUT | COPY | PASTE)? In the main theme in text styles? Maybe it's affected by one of the colorScheme properties? Or maybe it's defined in one of the ButtonTheme properties? Or it has it's own style property in the main ThemeData? We really need a list of all components and corresponding properties which style them. Thank you guys for your hard work!
