image_picker 0.8.7+2

Flutter plugin for selecting images from the Android and iOS image library, and taking new pictures with the camera.

Image Picker plugin for Flutter

A Flutter plugin for iOS and Android for picking images from the image library, and taking new pictures with the camera.

	Android	iOS	Web
Support	SDK 21+	iOS 11+	See image_picker_for_web

Installation

First, add image_picker as a dependency in your pubspec.yaml file.

iOS

Starting with version 0.8.1 the iOS implementation uses PHPicker to pick (multiple) images on iOS 14 or higher. As a result of implementing PHPicker it becomes impossible to pick HEIC images on the iOS simulator in iOS 14+. This is a known issue. Please test this on a real device, or test with non-HEIC images until Apple solves this issue. 63426347 - Apple known issue

Add the following keys to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

• NSPhotoLibraryUsageDescription - describe why your app needs permission for the photo library. This is called Privacy - Photo Library Usage Description in the visual editor.
  • This permission will not be requested if you always pass false for requestFullMetadata, but App Store policy requires including the plist entry.
• NSCameraUsageDescription - describe why your app needs access to the camera. This is called Privacy - Camera Usage Description in the visual editor.
• NSMicrophoneUsageDescription - describe why your app needs access to the microphone, if you intend to record videos. This is called Privacy - Microphone Usage Description in the visual editor.

Android

Starting with version 0.8.1 the Android implementation support to pick (multiple) images on Android 4.3 or higher.

No configuration required - the plugin should work out of the box. It is however highly recommended to prepare for Android killing the application when low on memory. How to prepare for this is discussed in the Handling MainActivity destruction on Android section.

It is no longer required to add android:requestLegacyExternalStorage="true" as an attribute to the <application> tag in AndroidManifest.xml, as image_picker has been updated to make use of scoped storage.

Note: Images and videos picked using the camera are saved to your application's local cache, and should therefore be expected to only be around temporarily. If you require your picked image to be stored permanently, it is your responsibility to move it to a more permanent location.

Example

final ImagePicker picker = ImagePicker();
// Pick an image.
final XFile? image = await picker.pickImage(source: ImageSource.gallery);
// Capture a photo.
final XFile? photo = await picker.pickImage(source: ImageSource.camera);
// Pick a video.
final XFile? galleryVideo =
    await picker.pickVideo(source: ImageSource.gallery);
// Capture a video.
final XFile? cameraVideo = await picker.pickVideo(source: ImageSource.camera);
// Pick multiple images.
final List<XFile> images = await picker.pickMultiImage();

Handling MainActivity destruction on Android

When under high memory pressure the Android system may kill the MainActivity of the application using the image_picker. On Android the image_picker makes use of the default Intent.ACTION_GET_CONTENT or MediaStore.ACTION_IMAGE_CAPTURE intents. This means that while the intent is executing the source application is moved to the background and becomes eligable for cleanup when the system is low on memory. When the intent finishes executing, Android will restart the application. Since the data is never returned to the original call use the ImagePicker.retrieveLostData() method to retrieve the lost data. For example:

Future<void> getLostData() async {
  final ImagePicker picker = ImagePicker();
  final LostDataResponse response = await picker.retrieveLostData();
  if (response.isEmpty) {
    return;
  }
  final List<XFile>? files = response.files;
  if (files != null) {
    _handleLostFiles(files);
  } else {
    _handleError(response.exception);
  }
}

This check should always be run at startup in order to detect and handle this case. Please refer to the example app for a more complete example of handling this flow.

Migrating to 0.8.2+

Starting with version 0.8.2 of the image_picker plugin, new methods have been added for picking files that return XFile instances (from the cross_file package) rather than the plugin's own PickedFile instances. While the previous methods still exist, it is already recommended to start migrating over to their new equivalents. Eventually, PickedFile and the methods that return instances of it will be deprecated and removed.

Call the new methods

Old API	New API
PickedFile image = await _picker.getImage(...)	XFile image = await _picker.pickImage(...)
List<PickedFile> images = await _picker.getMultiImage(...)	List<XFile> images = await _picker.pickMultiImage(...)
PickedFile video = await _picker.getVideo(...)	XFile video = await _picker.pickVideo(...)
LostData response = await _picker.getLostData()	LostDataResponse response = await _picker.retrieveLostData()
