Configuration #

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.

Android #

• Add UCropActivity into your AndroidManifest.xml

<activity
    android:name="com.yalantis.ucrop.UCropActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

Add permissions for Android #

In the android/app/src/main/AndroidManifest.xml add:

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera" android:required="true" />

• Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 33:

* android {
  compileSdkVersion 33
  ...
  }

Usage #

You can check permission status #

var permissionStatus = await ImageUtility.checkPermission();
 if(permissionStatus ){
 //
 }else{
 //Navigate to setting 
 }

File? image = await ImageUtility.imageFromGallery(imageQuality: 60);

File? image= await ImageUtility.imageFromCamera(imageQuality: 60 );
