I’m developing a mobile app using flutter framework with dart language, and I need a tree model dropdown, like in the first image.

In this component, we have a list of objects that contain objects (that are also selectable). I want to be able to search (in the search bar in the top) for the father objects or son objects.

Example:

I have 3 father nodes: A, B, C and for each one I have 2 son nodes.

A - A1, A2,

B - B1, B2

C - C1, C2

The first son node inside the father, must be all son nodes and if I click it, it will select all son nodes.

Whenever I click in a node (father or son) will select/deselect it.

If I click a father node, will also select all son nodes and put a selected icon in the father node, however if I select son nodes (but not all) the mark will appear as the second image.

In the end, I want to show the selected nodes as in the last image.
