In my app there is a group chat where each user has it's own color on their name just like Whatsapp group chat. But there are times where the name color blends with the background color (e.g yellow user name on a white bubble chat) which makes it difficult for users to read.

Here is the code where I generate the color:

for(var item in json.decode(conversation!.idReceiversGroup!)){
  if(!bubbleColor.map((e) => e.idUser).contains(item)){
     bubbleColor.add(BubbleColor(idUser: item, Color: Colors.primaries[Random().nextInt(Colors.primaries.length)]));
  }
}

Is there any solutions?

What type of Exception are you facing? – Dani3le_ Mar 15 '22 at 10:04
Light colors @Dani3le_ – aufa Mar 15 '22 at 10:04
Maybe you should add some shadow to your `Text` (user name) to highlight it more. – Ante Bule Mar 15 '22 at 10:10
so the only way is to add shadow? @AnteBule – aufa Mar 15 '22 at 10:19
Probably not the only way but one of the possibilities that occurred to me. – Ante Bule Mar 15 '22 at 10:27
ah okey, but is there a way to give conditional to not generate the light colors? @AnteBule – aufa Mar 15 '22 at 10:39
Maybe try checking like here https://stackoverflow.com/questions/68170447/detect-color-is-light-or-dark-in-flutter – Ante Bule Mar 15 '22 at 12:47
