Usage

Using ListView

import 'package:flutter/material.dart';
import 'package:zoom_view/zoom_view.dart';

void main() {
  runApp(const MaterialApp(home: 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 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 Scaffold(
      body: ZoomView(
        controller: controller,
        child: ListView.builder(
            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.
