Insert Custom Objects into a List of Custom Objects-CodePudding

I have a ListView of custom objects.

I'd like to insert a variety of other custom objects into my list.

So the goal would be something like this:

CustomObjectA
CustomObjectA
CustomObjectB
CustomObjectA
CustomObjectA
CustomObjectA
CustomObjectC
CustomObjectA
CustomObjectA
CustomObjectA
CustomObjectC

I may have some that I want to go to a specific row, whereas others may be every nth row.

The problem I see is I have List<dynamic> objects, but if I do something like:

objects.insert(
    3,
    CustomObjectB(),
);

I get an error as CustomObjectB is NOT a CustomObjectA.

What is the best way to achieve this?

CodePudding user response：

If the objects you add to ListView (ex. CustomObjectA) are Widgets, then List objects update it to List.

Or you can use List but if they are widgets List is required
