Flutter Solutions

Solution 1 - Flutter

removeWhere allows to do that:

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

See also List Dartdoc

Solution 2 - Flutter

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);

Solution 3 - Flutter

//For removing specific item from a list with the attribute value
replytile.removeWhere((item) => item.id == '001') 

//Remove item by specifying the position of the item in the list
replytile.removeAt(2)   

//Remove last item from the list
replytile.removeLast()

//Remove a range of items from the list
replytile.removeRange(2,5)

Solution 4 - Flutter

This also works

_listofTaskUI.removeAt(_quantity);

Solution 5 - Flutter

if you have a generic list

List<int> sliderBtnIndex = [];//Your list

sliderBtnIndex.remove(int.tryParse(index)); //remove
