Serious performance issues with nested ListViews
Here is a video of the performance issue in question. It occurs when I am scrolling inside the second page:
https://imgur.com/gNomm1T
  I am trying to create a comment tree that is expandable when tapped, however the comment tree ends up running extremely poorly. I have been trying to fix this over the past few days, however I have been having very little success.In short, I have have a "comment" widget that holds a ListView containing the parent comment followed by a ListView which builds more of these "comment" widgets. It acts recursively and it functions exactly as I would hope, however I am facing performance issues.I have tried utilizing the profiler, however I cannot discover why this is performing so badly.This is a screenshot of the profiler during normal operations. Everything seems quite normal:
https://imgur.com/PFrfE0SThis is a screenshot of the profiler during normal operations. It appears to be skipping every other frame:
https://imgur.com/1FplLUEThe most bizzare part to me is that it says the application is running at 60.0FPS. Hopefully you could see this in the video, but when I am viewing the comment tree, the scrolling is very jittery.The entire project can be viewed on GitHub here, however it is undocumented and a little but of a mess so I will try to summarize the important parts below.
  submission_comment.dart - This contains the comment widget

 Widget build(BuildContext context) { // This ListView acts as a column. It was originally implemented as a column, but some people said ListViews perform better return ListView( shrinkWrap: true, physics: NeverScrollableScrollPhysics(), primary: false, children: <Widget>[ // To listen for tap events to trigger the comment to collapse/expand InkWell( onTap: () { setState(() { expanded = !expanded; }); }, // The comment item. Not really that important child: Container( width: double.infinity, decoration: BoxDecoration( border: Border( left: BorderSide( width: 4.0, color: depthColor[widget.comment.depth % depthColor.length], ), ), ), child: Padding( padding: EdgeInsets.all(12.0), child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: <Widget>[ SubmissionCommentHeader(comment: widget.comment), SizedBox( height: 8.0, ), SubmissionCommentBody(comment: widget.comment), ], ), ), ), ), // This is where the 'recursion' occurs. If the parent comment has replies, a subsequent child comment tree will be built if (widget.comment.replies != null) Offstage( offstage: !expanded, child: Padding( padding: EdgeInsets.only(left: 4.0), child: SubmissionCommentTree( comments: widget.comment.replies, ), ), ), ], ); } 

 submission_comment_tree.dart

// Hopefully pretty explanatory. Builds a list of comments based on the comments provided to the widget. Widget build(BuildContext context) { return ListView.builder( physics: NeverScrollableScrollPhysics(), primary: false, shrinkWrap: true, itemCount: widget.comments.length, itemBuilder: (context, index) { if (widget.comments[index] is! Comment) { return null; } return SubmissionComment(comment: widget.comments[index]); }, ); } 

  Thank you very much for any help or insight regarding this problem!

Recommedations of well explained flutter resources needed
I am a beginner Android (Java) developer who recently started Flutter and Dart for building mobile apps. I was working with the Udacity course < https://classroom.udacity.com/courses/ud905 >. The only one of its kind on Udacity but it was difficult because the codes were not explained and the quizzes were just frustrating. I personally feel it isn't structured for me to learn the language well. I want someone to recommend a good material. Thanks

Payment options for Flutter application
Hi all!I'm a developer with a high background(Java, C#). And I learn Flutter for 6 months.I successfully created and posted to AppStore and Google Market several free applications. And now I want to post a new application with payment options. The free version of my application contains several features. If the user wants to unlock all the features, he can buy the full version.And here I'm stuck.Let's imagine: the user installs my application, he buys the full version. After some time, he removes my application. And after some time, he installs my application again. So, the question is: how to understand that this user already bought the full version of the application? Some external database? Firestore? How to understand that it is that user? How to identify that user? Add login and password? I think this is a bad idea because my application - is just two screens. This is a small application. Login\Password\Registration for small application? Hmmm.. I don't think so. Maybe I'm wrong?Also, how about different platforms? For example, the user has an IOS and android device. He bought the full application on IOS. How to understand this user can access the full version of the application on Android?
