PinchZoom 是一个 Flutter 包，通过 Flutter 的 InteractiveViewer 实现直观的捏合缩放功能。它允许用户使用触摸手势缩放和拖动图像，并在手势结束时自动将图像恢复到原始大小和位置。该包设计简洁，跨平台性能流畅，可无缝集成到图像查看界面中。它支持所有主要平台，包括 Android、iOS、Web、macOS、Windows 和 Linux，非常适合需要交互式图像探索的跨平台应用。

A widget based on Flutter's Interactive Viewer that makes picture pinch zoom, and return to its initial size and position when released.
This package offers Instagram based pinch zooming that feels more responsive than other similar packages.
The package is designed for zooming in on images; however, it can also be used to zoom in on a video.
Add this to your pubspec.yaml dependencies:
pinch_zoom: ^2.0.1
Add the widget to your app like this (It automatically takes the size of the image you pass to it):
PinchZoom(
child: Image.network('https://placecats.com/640/360'),
maxScale: 2.5,
onZoomStart: (){print('Start zooming');},
onZoomEnd: (){print('Stop zooming');},
),
