What types of data trees are used in Flutter for building interfaces or architecture?

In Flutter, the following types of data trees are used for building interfaces and architecture:

• Widget Tree — the foundation of the UI in Flutter. Each element of the interface is represented by a widget, and all widgets are organized into a hierarchical tree.

• Element Tree — reflects the current state of widgets in the application. Elements connect widgets with render objects and manage their lifecycle.

• Render Tree — responsible for drawing on the screen. Contains objects that directly render pixels.

These trees are closely linked and ensure efficient updating and rendering of the interface.

An example of a simplified structure:

// Widget Tree
Column(
  children: [
    Text('Hello'),
    ElevatedButton(onPressed: () {}, child: Text('Press')),
  ],
)

Here, Column is the root widget, which has child widgets Text and ElevatedButton, forming a widget tree.
