Flutter Photo Uploader is a Flutter package which Uses the Camera Package

flutter_photo_uploader

Flutter Photo Uploader is a Flutter package which uses the Camera package to take a picture, crop it, and post the data to an endpoint. It’s simple and lightweight! It’s currently a work in progress with tests being added in the near future. Functionality is also pretty limited right now but it is very easy to use. Images can only be cropped as squares with additional functionality being added to handle all types of cropping.
