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(
                controller: controller,
                itemCount: 10000,
                itemBuilder: (context, index) {
                  return Center(
                      child: Text("text $index")
                  );
                }
            ),
          ),
        )
    );
  }
}

Note that the controller argument most be set for your ListView.

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.
