Any recommendations for handling User Generated Content?
I am developing a social reading platform in flutter - so you can read books and comment on them and see other people's comments as you read. It's pretty simple, but obviously there are some considerations to be made for the user-generated-content as it is meant to be a public platform. I was wondering if anyone has experience doing this with flutter, and complying with both Apple and Google's guidelines on the matter, in a relatively bare-bones way?Google says:(paraphrased)- have TOS and define what inappropriate content is- implement "robust, effective and ongoing UGC moderation", followed by "as is reasonable and consistent"- be able to report users, and block abusive users from the platform- prevent monetization from "encouraging objectionable behavior"​Apple Says:- a method of filtering objectionable material- a mechanism to report users and block abusive users from the platform- publish your contact info​My impression from reading this is that Google's guidelines are somewhat more strict than Apple's. But apple's first point seems to be something that Google doesn't require - if that means have a direct filter in the app itself to, say, detect if a user has entered a bad word from some pre-defined list?Also, what exactly does 'robust, effective, and ongoing moderation' mean? Is that something more / different than each user having the ability to report another user, and giving the top-level moderators access to a list of those reports + the ability to remove a user and his posts?My plan was to have new users' first 10 comments automatically submitted for moderation before they are publicly displayed. And after 10 comments, they can become (level-1) moderators themselves, their posts are submitted automatically (self-approved), and they can approve/disapprove of other new users' posts. And on top of that are users who have a more complete set of moderator actions, like viewing reports, deleting inappropriate usernames, and stuff like that.Any advice, feedback, experience, or thought on what to consider is appreciated!

App Store rejection based on trademark infringement
My app got rejected for containing pub.dev in the description/title."Tavern - A pub.dev client"I feel it's important so people know what it is. Does this really violate trademark rules? I read them and couldn't find any information verifying this. Is there a small change I can make to make this acceptable while keeping pub.dev in the name?Apple says:Guideline 4.1 - Design - CopycatsYour metadata appears to contain third party content.

[Breaking Change Proposal] CustomPaint can't set raster cache hints with null painters
If your app does not use CustomPaint, you can stop reading now. *Summary* In the proposal (https://ift.tt/31vnTET), if one builds a CustomPaint widget with null painter and null foregroundPainter, then the assertion would trigger if isComplex or willChange is set to true.

Flutter build process (preventing conflicts within dependencies, etc)
Does anyone know of an overview of the flutter build process? How it works, what runs first, in what order dependencies are compiled, how conflicts are resolved? Understandably, there are a ton of moving parts given what flutter offers. Especially if you start using plugins. Some of those plugins might call other native specific plugins, and so on. Each of these modules can have different build "requirements".List of moving parts as far as I can tell:build tools/processes used:pub (dart)gradle (android)cocoapods (apple)​uses Android X (yes/no)flutter SDK version range​gradle versioncompileSdkVersionminSdkVersiontargetSdkVersion​swift_versionios.deployment_targetplatform(honestly not sure what these 3 are but i've seen them in different places)So, as far as I can tell, (1) your flutter app, and (2) each it's dart/pub packages, and (3) all of their gradle/cocoapods dependencies could have their own and potentially conflicting settings.How much do we have to worry about this?There's no way that you can easily catalog each and look for conflicts.Which one takes priority? What happens when there are conflicts? For instance, what if my app's minSdkVersion is 19, but a dart/flutter plugin calls an android dependency that requires version 21? Would my app still compile (what about install and run)? What happens when it runs on a device running 19 that tries to use functionality provided by that plugin (not available until 21)?All is great now that I have my app running on my samsung s9 and iphone X for testing, but how in the world can I be sure there aren't some problems that would happen on other devices in the wild (with different OS versions, etc). I know I could theoretically create emulators for each OS for android/ios, but still i dont if that's enough to truly test for this.I think I could rest better understanding the role that each of these technologies play and how to be safe to ensure there are no conflicts.Thanks!

VSCode shortcut/extension for autocompleting parameters?
Sometimes when I watch flutter tutorials the youtuber presses a shortcut and an small popup with all the parameter options comes up, they are able to scroll to the option they want and click on it.This is similar to the "parameter hints" shortcut but not the same.As a follow-up, sometimes a parameter takes an implementation of an abstract class. Whats a quick way to search up all implementations of that abstract class in the flutter sdk.For example, im using the charts_flutter package, and want to specify a TickProviderSpec, but instead of the base tickproviderspec im supposed to specify a class which implements it. I want to know all the implementations of that class, since sometimes the implementation doesn't have the base class as part of its name autocomplete doesnt help.
