dynamic_treeview - A flutter package #

A Dynamic treeview that can be build using dynamic parent/child relationship. It supports indefinite category/subcategory lists with horizontal and vertical scrolling

Getting Started #

In your flutter project add the dependency:

        dynamic_treeview: 1.0.0+2

Import package #

BaseModel implementation #

    Since DynamicTreeView is build using data having parent/child relationship, 
    you must create a class model that implements BaseModel and overrides the method 
    like getParentId(), getId() and getTitle() and return appropriate values to make it work. 
    The method getExtraData() has also been added just in-case if any extra data is needed when child/parent is tapped.

Sample Usage #

        data: getData(), // pass here List<BaseModel>
        config: Config(
                TextStyle(color: Colors.black, fontWeight: FontWeight.w600),
            rootId: "1",
                EdgeInsets.only(left: 16, top: 0, bottom: 0)),
        onTap: (m) {
        //action on tap
        width: MediaQuery.of(context).size.width,
