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.

Excited!! Check more info about our Flutter App Development company.

PhotoView widget also can show any widget instead of an image, such as a container or Text.

Some Basic Properties:-

scrollDirection
enableRotation
physics
controller
backgroundDecoration
loadingBuilder
maxScale
minScale

Implementation of PhotoView in Flutter:

Step 1: Add the dependencies

Add dependencies to pubspec — yaml file.

1	photo_view: ^0.11.0

Step 2: Importing

1	import 'package:photo_view/photo_view.dart';

Step 3: Run the flutter package get

Code Implementation:-

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) {
    return Scaffold(
      backgroundColor: Colors.white,
      appBar: AppBar(
        title: Text("PhotoView Demo"),
      ),
      body: Center(
        child: Container(
          height: 200,
          color: Colors.white,
          width: 200,
          child: PhotoView(
            backgroundDecoration: BoxDecoration(color: Colors.white),
            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) {

return Scaffold(

backgroundColor: Colors.white,

appBar: AppBar(

title: Text("PhotoView Demo"),

body: Center(

child: Container(

height: 200,

color: Colors.white,

width: 200,

child: PhotoView(

backgroundDecoration: BoxDecoration(color: Colors.white),

enableRotation: true,

// disableGestures: true,

// tightMode: true,

imageProvider: AssetImage("assets/images/flutter2.jpeg"),

maxScale: 200.0,

);

}
