A RaisedButton that will call image_picker to choose the image.A Container that will show our selected image (it’ll look nicer is all).I created a new Flutter application with basic functionality that has: We will also have to use the dart:io package for the File class. I’ll also be using the image_picker plugin (I’m using ^0.6.7+14) to choose the image from the emulator. Path_provider (I’m using ^1.6.24): This plugin allows easy access to the device’s cache to save the image copy after EXIF data stripping. Setup:įlutter_image_compress (I’m using ^0.7.0): This is the plugin that removes the EXIF data. If you want to keep the metadata, you can set the keepExif parameter to true. The TL DR: flutter_image_compress automatically strips all metadata from an image. Just FYI - In this article, I’ll be using the terms “EXIF data” and “metadata” interchangeably. However, some platforms, such as Google Cloud Storage, do not remove metadata automatically - and if their API doesn’t allow this functionality, then you will have to implement it yourself. You will want to check with your storage medium first, as they may already strip all metadata from any file that is uploaded via their services. Depending on your use-case, of course, it is a good idea to delete this information before you store it for the world to access. This information is stored in the image’s metadata, also known as the EXIF (Exchangeable Image File Format) data. You may already know that images can contain sensitive information such as GPS coordinates of where the image was taken.
