pinch_zoom_image's Introduction

Pinch Zoom Image

A widget that makes picture pinch zoom, Instagram style!

Installation

Add this to your pubspec.yml dependencies:

pinch_zoom_image: "^0.2.5"

How to use

Add the widget to your app like this (It automatically takes the size of the image you pass to it):

PinchZoomImage(
  image: Image.network('https://i.imgur.com/tKg0XEb.jpg'),
  zoomedBackgroundColor: Color.fromRGBO(240, 240, 240, 1.0),
  hideStatusBarWhileZooming: true,
  onZoomStart: () {
    print('Zoom started');
  },
  onZoomEnd: () {
    print('Zoom finished');
  },
),

The zoomedBackgroundColor is the color that fills the image's space when the use is zooming it and moving it on the screen.

If you want images from internet to be cached for offline use or data saving, you can also use this with the cached_network_image widget:

PinchZoomImage(
  image: CachedNetworkImage(
    imageUrl: 'https://i.imgur.com/tKg0XEb.jpg',
  ),
  zoomedBackgroundColor: Color.fromRGBO(240, 240, 240, 1.0),
  hideStatusBarWhileZooming: true,
),

Enjoy!

pinch_zoom_image's Issues

pinch_zoom_image: ^0.2.5 Gradle plugin needs to be upgraded

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher.
The following dependencies do not satisfy the required version:
project ':pinch_zoom_image' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

Kotlin Gradle plugin version build error

Hey,
I'm trying your plugin, but when I compiled my app.
Build crashed with this exception:

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.10 and higher.
The following dependencies do not satisfy the required version:
project ':pinch_zoom_image' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

Out of date

Remove native portion

Is it possible to remove the native code portion altogether and use Flutters SystemChrome methods?

Besides, the Kotlin version is out of date again:

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher.
The following dependencies do not satisfy the required version:
project ':pinch_zoom_image' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

Highly suggest to move this back to Java..

Please upload a simple update and upgrade your Kotlin version so we can all enjoy the latest gradle plugin.

I wanted to know if this library is androidx compatible or not because it is breaking the build.

How to make zoom center as the focalPoint?

At this moment, When I zoom in the image, it just zooms in, and the zoom center is the center of the image.Can we make center of our two fingers(see focalPoint) as the zoom center.

Just as Instagrm, when we zoom in the image only(DO NOT scale), the overlay image will also change it's position to make out finger cenrer of the screen.

High resolution image zoom result in black screen

I am running the demo with one of my high resolution image. And I can see the image, even zoom it a little bit, but after I zoom it to certain ratio, it will black out, and when it zoom back, it will show the picture again. I think this is a bug.

Image:

Code:
`import 'package:flutter/material.dart';
import 'package:pinch_zoom_image/pinch_zoom_image.dart';
import 'package:cached_network_image/cached_network_image.dart';
import 'package:photo_view/photo_view.dart';

class PinchZoomImageDemo extends StatelessWidget {
@OverRide
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Pinch Zoom Image Demo'),
),
body: ListView(
children: [
PinchZoomImage(
image: CachedNetworkImage(
imageUrl: web_url_of_my_image',
),
zoomedBackgroundColor: Color.fromRGBO(240, 240, 240, 1.0),
),
],
),
);
}
}`

black background when zomed

When I zoom the image, the image backdroud is black. How can I change it, because I had set the zoomedBackgroundColor to white but don't work!
