Project description:
"I’m building a mobile app around an existing mind-mapping solution and I need a standalone Flutter widget that reproduces the core map experience inside my app. You will work from my full written specification but, in short, the widget must:

• Render a hierarchical map whose nodes can be clicked to expand or collapse, dragged anywhere on the canvas, and tapped to edit their text in place.
• Support theme switching (colours, fonts, connector styles) driven by a simple JSON or model class so new themes can be added without code changes.
• Offer at least one export path—ideally to PNG/SVG as well as to my map’s native JSON structure—so users can share or persist their work.

Smooth performance on both Android, iOS, MacOs, Windows, Web is essential. You’re free to use Canvas, CustomPainter, or any other Flutter-friendly graphics library, provided the final widget remains fully reactive and fits naturally into the standard Flutter build/render cycle. Please wrap it as a reusable package with clear public APIs, include a minimal demo screen that shows real-time editing, and document any third-party libraries you pull in.

Send back:
1. The complete Dart source with clean, commented code.
2. A demo page illustrating every required interaction.
3. A short README explaining setup, theming, and export hooks.

If you have experience building rich interactive Flutter components, especially graph or diagram editors, I’d love to see examples." (client-provided description)
