Brother printer SDK for Flutter using native SDK v4 on iOS and v3 on Android.


Be sure to read requirements of the native SDK:

Add this to your package's pubspec.yaml file:

  brother_printer: ^0.1.3


In the Podfile uncomment:

    platform :ios, '10.0'

In the Info.plist add:

    <string>Bluetooth is required for connection to your printer.</string>
    <string>Bluetooth is required for connection to your printer.</string>
    <string>${PRODUCT_NAME} uses the local network to discover printers on your network.</string>


Connection doesn't seem to work on emulator.

Add permissions:

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

You have to manually authorized the location permission on the device (will be improve later).


You may have some crash in release mode, you can add this to your android/app/build.gradle:

    buildTypes {
        release {
            minifyEnabled false
            shrinkResources false

            signingConfig signingConfigs.release


There are difference between what return the iOS version and the Android version

    print('${device.model.nameAndroid} - ${device.source} - ${device.modelName} - ${device.ipAddress} - ${device.printerName} - ${device.macAddress} - ${device.nodeName} - ${device.serialNumber} - ${device.bleAdvertiseLocalName}');
