Dart – Update List items including condition

I want to change the items of a list whose variable seen is false,

my model:

class Message{
  String text;
  bool seen;
  Message(this.text, this.seen)
}

my list:

List<Message> messages = [

Message('hi', false),
Message('hi2', true),
Message('hi4', false),
Message('hi6', false),
Message('hi8', true),

];

>Solution :

To change the items of the messages list whose seen variable is false, you can iterate through the list and use a conditional statement to check if the seen variable is false. If it is false, you can modify as you need.

Here’s an example code snippet to achieve this:

for (var message in messages.where((element) => element.seen == false)) {
  message.seen = true;
}
