Android

You can use Permission_handler, a permissions plugin for Flutter. Require and add the following permissions in your manifest:

Add this to the proguard-rules.pro

-keepclassmembers class ai.deepar.ar.DeepAR { *; }

for release mode modify and add to your BuildType in your build.gradle

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    <uses-permission android:name="android.permission.FLASHLIGHT" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

iOS

You only need add the permission message on the Info.plist

    <key>NSCameraUsageDescription</key>
    <string>Allows you to capture your best moment</string>
	<key>io.flutter.embedded_views_preview</key>
	<true/>
    <key>NSPhotoLibraryAddUsageDescription</key>
    <string>Allows you to capture your best moment</string>
    <key>NSMicrophoneUsageDescription</key>
    <string>Needs access to your mic to help your record voice notes on chat/message conversations</string>
