Flutter get list values to another list

Question

I have a List in the following format:

List<ImageCollections> collectionlist;

It looks like this:

collectionlist = [
  { collectionname: 'abc', srcimage: url1, collectionimgnumber: 5, hreflink: link1 },
  { collectionname: 'xyz', srcimage: url2, collectionimgnumber: 4, hreflink: link2 },
  ...
];

Is there a way I can create a new List containing only the srcimage of each entry?

The new list should look like this:

newList = [ url1, url2, ... ];

You can use Iterable.map:

newList = collectionlist.map((object) => object.srcimage);

Use the list map function:

srcimagelist = collectionlist.map((x) => x.srcimage);
