How to find a Map in a Map List?

In my code I have a list of Maps, something like this:

List<Map<String, dynamic>> list;

list = [
   {"name" : "name1", "date" : '01/08/2020'}
   {"name" : "name2", "date" : '01/08/2020'}
];

obs: instead of String I'm using DateTime object to set the value of date key

but when I try to delete some item in list using

list.removeAt(list.indexOf({"name" : "name1", "date" : '01/08/2020'}));

the function indexOf() return -1.

How can i find a item to delete or modify in this list?

You could so something like this using removeWhere

list.removeWhere((m) => m["name"] == "name1" && m["date"] == "01/08/2020");
