Flutter移除清单项目 [英] Flutter Remove list item

问题描述

我的飞镖脚本中有一个问题，这是我的脚本:

  List< ReplyTile>Replytile =新的List< ReplyTile>();Replytile.add(新的ReplyTile(member_photo:照片"，member_id:"001"，日期:"2018年1月1日"，member_name:丹尼斯"，id:"001"，文字:你好.")); 

我的问题是:如何使用 id = 001 删除 List< ReplyTile> 上的项目.

预先感谢

解决方案

removeWhere 允许这样做:

  replytile.removeWhere((item)=> item.id =='001') 

另请参见列出Dartdoc

I have a question in my flutter dart script, this my script:

List<ReplyTile> replytile = new List<ReplyTile>();

replytile.add(
    new ReplyTile(
        member_photo: "photo",
        member_id: "001",
        date: "01-01-2018",
        member_name: "Denis",
        id: "001",
        text: "hallo.."
    )
);

My question is: how to remove items on List<ReplyTile> with id = 001.. ?

Thanks in advance

解决方案

removeWhere allows to do that:

replytile.removeWhere((item) => item.id == '001')
