Image Widget is generally a simple component that represents a thing or a group of things pictorially or which simply boosts the message or the text with a pictorial example to make the user understand better through the images that are displayed along with the paragraphs or the blog of data. So let’s start with how to crop an image in flutter.

How to Crop an Image In Flutter??

I would probably use a BoxDecoration with a DecorationImage. The alignment and fit properties are used to determine how your image is cropped.

You can use an AspectRatio Widget if you don’t want to hard code a height on the Container Widget.

Consider a code snippet like the below:

import 'package:flutter/material.dart';

void main() {
  runApp(new MaterialApp(
    home: new MyHomePage(),

class MyHomePage extends StatelessWidget {

  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text("Image Crop Example"),
      body: new Center(
        child: new AspectRatio(
          aspectRatio: 487 / 451,
          child: new Container(
            decoration: new BoxDecoration(
              image: new DecorationImage(
                fit: BoxFit.fitWidth,
                alignment: FractionalOffset.topCenter,
                image: new NetworkImage(''),

We will get output like a below:

You can also directly use the Image class with BoxFit and do something like:

new Image.asset(
  fit: BoxFit.cover,

Take a look at brendan-duncan/image, it’s a platform-independent library to manipulate images in Dart.

You can use the function:

Image copyCrop(Image src, int x, int y, int w, int h);
