Flutter Remove list item

问题

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

回答1:

removeWhere allows to do that:

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

See also List Dartdoc

回答2:

In your case this works:

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

For list with specific datatype such as int, remove also works.Eg:

List id = [1,2,3];
id.remove(1);

This also works

_listofTaskUI.removeAt(_quantity);
