I've asked chatgpt and it gave me the following :
1. Canvas Zoom and Pan:
FlutterFlow doesn’t have built-in support for fully zoomable and pannable canvases.
However, you could create a pseudo-zoom effect by allowing elements to scale up or down when users interact with them, simulating a zoomed view.
For true zoom and pan functionality, you’d likely need to use custom Flutter code (e.g., using a Transform widget with GestureDetector for pinch-to-zoom and drag). You can integrate custom code in FlutterFlow by using custom actions or custom widgets, though this requires knowledge of Flutter.
2. Interactive Mind Map with Expandable Nodes:
The structure of linked nodes, like a mind map, can be achieved by placing widgets in a stack or dynamically using collections (like Firestore) to populate the content.
Each node (e.g., "Subtopic") could be a button or a container that navigates to additional details or branches.
3. Scrolling or Dragging for Navigation:
You could use a Stack widget inside a SingleChildScrollView for horizontal and vertical scrolling, enabling users to navigate through a large layout.
For a more fluid navigation experience, you'd again need custom code to add features like dragging across the screen.
