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

dependencies:
  brother_printer: ^0.1.3

In the Podfile uncomment:

    platform :ios, '10.0'

In the Info.plist add:

    <key>NSBluetoothAlwaysUsageDescription</key>
    <string>Bluetooth is required for connection to your printer.</string>
    <key>NSBluetoothPeripheralUsageDescription</key>
    <string>Bluetooth is required for connection to your printer.</string>

    <key>UISupportedExternalAccessoryProtocols</key>
    <array>
        <string>com.brother.ptcbp</string>
    </array>
    <key>NSBonjourServices</key>
    <array>
        <string>_printer._tcp</string>
        <string>_pdl-datastream._tcp</string>
        <string>_ipp._tcp</string>
    </array>

Android

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).

Warning

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
        }
    }
