This package uses native implementations to resize an image. It should be fast compared to the image package. It only supports PNG as output at the moment.
This package has zero dependencies.
Features
- Supported inputs: JPEG, PNG, GIF, Animated GIF, WebP, Animated WebP, BMP, and WBMP
- Supported outputs: PNG
Getting started

Usage
import 'package:fast_image_resizer/fast_image_resizer.dart';
import 'dart:typed_data';
final rawImage = await rootBundle.load('assets/someImage.png');
final bytes = await resizeImage(Uint8List.view(rawImage.buffer), width: 150);
if (bytes != null) {
final imageWidget = Image.memory(Uint8List.view(bytes.buffer));
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
title: const Text("Image"),
content: imageWidget,
);
}
);
}
or
final ImagePicker _picker = ImagePicker();
final XFile? image =
await _picker.pickImage(source: ImageSource.gallery);
if (image != null) {
final rawImage = await image.readAsBytes();
final bytes = await resizeImage(Uint8List.view(rawImage.buffer), height: 250);
if (bytes != null) {
final testing = Image.memory(Uint8List.view(bytes.buffer));
showDialog(
context: context,
builder: (BuildContext context) {
