In this blog,we will implement Octo image package in flutter.
It uses an image library for showing placeholders , error widget and transform your image.
This package needs an Image Provider to show the image.We can either supply the widget with a placeholder or progress indicator , an imageBuilder and/or an error widget.
We will stepwise implement octo_image package.
You may also check our Flutter app development page.
Step1:-Add the plugin
Add the octo_image latest dependency in your pubspec.yaml file.
|
1 |
octo_image: ^1.0.2 |
Run flutter pub get command in your terminal for importing the package.
Step2:-Import the plugin
|
1 2 |
import 'package:flutter/material.dart'; import 'package:octo_image/octo_image.dart'; |
import the plugin as shown above in your main.dart file.
Step3:-How to use?
We have created a method which will show a blurr placeholder till image is loading from network.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
Widget _simpleBlur() { return AspectRatio( aspectRatio: 269 / 173, child: OctoImage( image: const NetworkImage('https://images.pexels.com/photos/674010/pexels-photo-674010.jpeg?cs=srgb&dl=pexels-anjana-c-674010.jpg&fm=jpg'), placeholderBuilder: OctoPlaceholder.blurHash( 'LEHV6nWB2yk8pyo0adR*.7kCMdnj', ), errorBuilder: OctoError.icon(color: Colors.red), fit: BoxFit.cover, ), ); } |
for showing image loading in circular avatar like social app.Add the below method
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
Widget _circleAvatar() { return SizedBox( height: 75, child: OctoImage.fromSet( fit: BoxFit.cover, image: const NetworkImage( 'https://thumbs.dreamstime.com/b/d-image-abstract-tunnel-diagonal-black-white-stripes-optical-illusion-168695979.jpg', ), octoSet: OctoSet.circleAvatar( backgroundColor: Colors.red, text: const Text("M"), ), ), ); } |
Now we have completed the code implementation.It’s time to check the output.
Step4:-Output
Let’s check the output of our implemented code.
alt=”” width=”250″ height=”513″>
you can see in above video that i have implemented the octo image package usage.It is very important to handle the view till image is loading from network.This gives a positive impact for our application.
