Widget that allows both zooming and scrolling a ListView or other Scrollables

Features

Scroll a ListView while it is zoomed in with fling velocity

Usage

Using ListView

import 'package:zoom_view/zoom_view.dart';


void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});
  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  ScrollController controller = ScrollController();
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home:  Scaffold(
          body: ZoomListView(
            child: ListView.builder(
                physics: const NeverScrollableScrollPhysics(),
                controller: controller,
                itemCount: 10000,
                itemBuilder: (context, index) {
                  return Center(
                      child: Text("text $index")
                  );
                }
            ),
          ),
        )
    );
  }
}

note that the controller argument most be set, and the the physics must be set to NeverScrollableScrollPhysics

Using some other scrolling list

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

  @override
  State<ZoomViewExample> createState() => _ZoomViewExampleState();
}

class _ZoomViewExampleState extends State<ZoomViewExample> {
  ScrollController controller = ScrollController();
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home:  Scaffold(
          body: ZoomView(
            controller: controller,
            child: ListView.builder(
                physics: const NeverScrollableScrollPhysics(),
                controller: controller,
                itemCount: 10000,
                itemBuilder: (context, index) {
                  return Center(
                      child: Text("text $index")
                  );
                }
            ),
          ),
        )
    );
  }
}

Note that here the controller is given both to the ZoomView and the list. Other Scrollables that use ScrollController should work as well. Make sure that NeverScrollableScrollPhysics ot some equivalent is set
