Freely moveable Flutter Widget

I need a special Widget.

Hey, I need the name pros.

Is there a widget that can be moved freely. Like how you can just move on with maps?

So basically scrollable in all directions.

You can use draggable widget for that simply wrap your widget like this

Draggable(
              data: 'Flutter',
              child: FlutterLogo(
                size: 100.0,
              ),
              feedback: FlutterLogo(
                size: 100.0,
              ),
              childWhenDragging: Container(),
            )

You can check InteractiveViewer Her is a basic demo:

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  static const String _title = 'Flutter Code Sample';

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: _title,
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  late Offset _offset;

  @override
  void initState() {
    _offset = const Offset(0, 0);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text(_offset.toString())),
      body: SizedBox.expand(
        child: InteractiveViewer(
          onInteractionUpdate: (details) => setState(() {
            _offset = details.focalPoint;
          }),
          boundaryMargin: const EdgeInsets.all(1000.0),
          minScale: 0.1,
          maxScale: 3,
          child: Center(
            child: TextButton(
              child: const Text('Drag me'),
              onPressed: () {
              },
            ),
          ),
        ),
      ),
    );
  }
}
