Project Settings

Permissions

iOS/macOS

Add the following entry to your Info.plist file,

located in <project root>/ios/Runner/Info.plist and <project root>/macos/Runner/Info.plist:

<key>NSCameraUsageDescription</key><string>$(PRODUCT_NAME) Camera Usage!</string><key>NSMicrophoneUsageDescription</key><string>$(PRODUCT_NAME) Microphone Usage!</string>

This entry allows your app to access camera and microphone.

Android

Ensure the following permission is present in your Android Manifest file,

located in <project root>/android/app/src/main/AndroidManifest.xml:

<uses-feature android:name="android.hardware.camera" /><uses-feature android:name="android.hardware.camera.autofocus" /><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

If you need to use a Bluetooth device, please add:

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

Other Settings

If necessary, in the same build.gradle you will need to increase minSdkVersion of defaultConfig up to 21 (currently default Flutter generator set it to 16).

Important reminder

When you compile the release apk, you need to add the following operations,

Edit <project root>/android/app/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+            minifyEnabled true+            useProguard true++            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }

And create new file <project root>/android/app/proguard-rules.pro
