Image Picker Tutorial in Flutter

In this tutorial, we'll go over how to install and use the Image Picker plugin in Flutter. We'll also cover how to select images from the camera roll, and how to take photos with the camera in Flutter.

Installing Image Picker into Flutter

The first step is to install the Image Picker plugin into your Flutter project. To do this, add the following line of code to your pubspec.yaml file:

dependencies:
  image_picker: <latest_version>

Then, run the following command in the terminal to install the plugin:

flutter pub get

Selecting Images from the Camera Roll

Once the plugin is installed, you can use it to select images from the camera roll. To do this, you'll need to first create an instance of the ImagePicker class:

final picker = ImagePicker();

Then, you can call the picker.getImage function to open the photo library and allow the user to select an image. This function returns a File object that contains the image data:

final pickedFile = await picker.getImage(source: ImageSource.gallery);

Taking Photos with the Camera in Flutter

In addition to selecting images from the camera roll, the Image Picker plugin also allows you to take photos directly with the camera. To do this, you'll need to call the picker.getImage function again, but this time set the source argument to ImageSource.camera:

final pickedFile = await picker.getImage(source: ImageSource.camera);
