How to Efficiently Specify Photo Quality in Flutter MultiImagePicker

In today's digital world, sharing and uploading photos is a commonplace activity in mobile applications. However, uploading high-quality images can be time-consuming, especially when multiple images are involved. Are you facing a similar issue while using Flutter's MultiImagePicker? Need to upload several photos, but don’t want to deal with the delays caused by high-resolution images? Don't worry; this guide has got you covered!

The Problem

While using the Flutter MultiImagePicker, one of the challenges developers face is managing the quality of the images they want to upload. High-resolution images can significantly slow down the upload process and complicate handling in the database. For instance, if your application requires users to upload several images, the overall experience could be hampered by long wait times due to the larger file sizes.

The Solution

Fortunately, the MultiImagePicker package offers a straightforward way to not only pick images but also compress them before uploading. Compression helps reduce the size of the images without noticeably sacrificing quality. Here's how you can efficiently specify the quality of a photo using MultiImagePicker, and send these images to your database in a timely manner.

Step 1: Picking Images

First, you can use MultiImagePicker to allow users to select multiple images. For example:

Step 2: Compressing Images

After picking the images, you need to compress them before sending them to the database. The getThumbByteData() method from the Asset class can be utilized to achieve this. You can specify the desired width, height, and quality of the images. Here’s a sample code snippet:
