BitmapDescriptor.fromAssetImage returns null
Hi everyone,​Since fromAsset is deprecated and doesn't provide size functionality, I moved to use fromAssetImage (which is a future function), however it is not working properly where I get default marker due to null.​

var Icon_num = 1; icon: correct_icon(Icon_num) 

​

BitmapDescriptor correct_icon(String num) { var config = ImageConfiguration(size: Size(32, 32)); String Image_String; switch (num) { case "1": Image_String = 'assets/num/1.png'; break; case "2": Image_String = 'assets/num/2.png'; break; case "3": Image_String = 'assets/num/3.png'; break; case "4": Image_String = 'assets/num/4.png'; break; case "5": Image_String = 'assets/num/5.png'; break; case "6": Image_String = 'assets/num/6.png'; break; case "7": Image_String = 'assets/num/7.png'; break; case "8": Image_String = 'assets/num/8.png'; break; case "9": Image_String = 'assets/num/9.png'; break; default: Image_String = 'assets/num/0.png'; break; } BitmapDescriptor myIcon; BitmapDescriptor.fromAssetImage(config, Image_String).then((onValue) { setState(() { myIcon = onValue; }); }); return myIcon; } 

​To diagnose this code, I have added, print('Before) before the BitmapDescriptor.fromAssetImage function, print('inside') inside the function and print('after') after the function. What I got is:​Beforeafterinside​So I think the code is not being executed properly.

Is Overlapping ListItems (Puzzle shaped items) inside a ListView possible?
🧩 🧩🧩Lets say I have puzzle pieces as 'ListItem's and I want to have infinite vertical scrolling for this 'ListView'. The contents of the puzzle pieces are taken from server.The problem I am having is the items shapes are not simple rectangles, but instead puzzle piece shapes. These interlock each other meaning the 'ListItem's overlap along their height.What would be a strategy to overcome this issue in Flutter? I know about stacks and can easily make a view using stack and positioned puzzles inside of it. However since i need them to be scrolled infinitely I don't know what the performance would be

Has anyone tried using absurdly large DataTables?
Specifically, I'm talking about this one.I'm trying to show this table inside a Flutter app for some testing. API is here, and it's based on the table here. I was hesitating between showing a list of Cards, ListTiles, an ExpansionPanel or a DataTable.I've looked at some tutorials to see some screenshots on what it looks like before trying to implement it, but they all use a reasonable amount of columns, which makes it impossible to imagine what would happen if a DataTable was needlessly large. Is it responsive?So... How do you personally show such tables?
