سلام استاد.ممنونم از وقتی که میذارید
من برای یادگیری بهتر از کد آماده استفاده کردم تا هم چالش برام ایجاد بشه و هم مثال هام به بازار کار نزدیکتر بشه.
اما متاسفانه این کد از چالش عبور کرده.
من دیشب فهمیدم که نباید داخل مدل بصورت مستقیم از api استفاده کرد😀😀😀
الان این کد که مدل هست رو چطور میتونم داینامیک کنم؟

class Chat {
  final String name, lastMessage, image, time, status, number, joinDate;
  final bool isActive, isSeen;
  bool isSelect;
  final int msgTotal;
  final List<String> images;

  Chat({
    this.name = '',
    this.lastMessage = '',
    this.image = '',
    this.time = '',
    this.isActive = false,
    this.isSeen = false,
    this.msgTotal = 0,
    this.status = '',
    this.number = '',
    this.joinDate = '',
    this.isSelect = false,
    required this.images,
  });
}

شما مدل رو رو داینامیک نمیکنی
شما اطلاعات رو میگیری و تو مدل فقط نگه داری میکنی
یک مدل نه وظیفه برگردوندن اطلاعات از api رو داره نه پویا سازی
فقط وظیفه نگه داری و تغییر داره
