Kotlin, Gradle, AGP

We ship this plugin with Kotlin 1.7.22. If your projects use a lower version of Kotlin/Gradle/AGP, please upgrade them to a newer version.

Android 10 (Q, 29)

If you're not setting your compileSdkVersion or targetSdkVersion to 29, you can skip this section.

On Android 10, Scoped Storage was introduced, which causes the origin resource file not directly inaccessible through it file path.

If your compileSdkVersion or targetSdkVersion is 29, you can consider adding android:requestLegacyExternalStorage="true" to your AndroidManifest.xml in order to obtain resources:

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example">

  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32" />
  <!-- Devices running Android 13 (API level 33) or higher -->
  <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
  <uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />
  <!-- To handle the reselection within the app on devices running Android 14
       or higher if your app targets Android 14 (API level 34) or higher.  -->
  <uses-permission android:name="android.permission.READ_MEDIA_VISUAL_USER_SELECTED" />


  <application android:label="example" android:icon="@mipmap/ic_launcher"
        android:requestLegacyExternalStorage="true"></application>
</manifest>

Note: Apps that are using the flag will be rejected from the Google Play.

iOS config preparation

Define the NSPhotoLibraryUsageDescription , NSCameraUsageDescription and NSMicrophoneUsageDescription key-value in the ios/Runner/Info.plist:

<key>NSPhotoLibraryUsageDescription</key>
<string>In order to access your photo library</string>
<key>NSCameraUsageDescription</key>
<string>your usage description here</string>
<key>NSMicrophoneUsageDescription</key>
<string>your usage description here</string>

Usage

Request for permission

This plugin requires the user's permission to access the media library and camera . You should handle cases where the user denies the permission request.

Limited entities access

Limited entities access on iOS

With iOS 14 released, Apple brought a "Limited Photos Library" permission (PermissionState.limited) to iOS.

To suppress the automatic prompting from the system when each time you access the media after the app has restarted, you can set the Prevent limited photos access alert key to YES in your app's Info.plist (or manually writing as below):

<key>PHPhotoLibraryPreventAutomaticLimitedAccessAlert</key>
<true/>

Limited entities access on Android

Android 14 (API 34) has also introduced the concept of limited assets similar to iOS.

However, there is a slight difference in behavior (based on the emulator): On Android, the access permission to a certain resource cannot be revoked once it is granted, even if it hasn't been selected when using presentLimited in future actions.

Usage

1. Add the plugin to your pubspec.yaml file:

                                    context: context,
                                    style: PickerStyle(),
