PhotoView In Flutter

PhotoView in flutter enables images or any widgets to become able to zoom with user gestures such as rotate or pinch.

In this blog, we will learn how to use the PhotoView. Throughout this tutorial, we will learn how to do that by building a Flutter app.

It is a simple zoomable image widget in flutter. We can be able to provide the zoom and rotate effect by using simply using this widget. And it also provides the scaling factor that how much zoom effect you want.

      debugShowCheckedModeBanner: false,
    ));

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final imageList = [
    'assets/images/flutter.png',
    'assets/images/flutter2.jpeg'
  ];

  @override

            enableRotation: true,
            // disableGestures: true,
            //  tightMode: true,
            imageProvider: AssetImage("assets/images/flutter2.jpeg"),
            maxScale: 200.0,
          ),
        ),
      ),
    );
  }
}

import 'package:flutter/material.dart';

import 'package:photo_view/photo_view.dart';

void main() => runApp(MaterialApp(

home: MyApp(),

debugShowCheckedModeBanner: false,

));

class MyApp extends StatefulWidget {

@override

_MyAppState createState() => _MyAppState();

}

class _MyAppState extends State<MyApp> {

final imageList = [

'assets/images/flutter.png',

'assets/images/flutter2.jpeg'

];

@override

Widget build(BuildContext context) {

);

}
