Print Response Intent Filter Example

<!-- Example of intent filter to receive print responses from Lio, change host and scheme if needed -->
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data
        android:host="dev.mauricifj"
        android:scheme="print_response" />
</intent-filter>

Payment Response Intent Filter Example

<!-- Example of intent filter to receive payment responses from Lio, change host and scheme if needed -->
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data
        android:host="dev.mauricifj"
        android:scheme="payment_response" />
</intent-filter>

Reversal Response Intent Filter Example

<!-- Example of intent filter to receive reversal responses from Lio, change host and scheme if needed -->
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data
        android:host="dev.mauricifj"
        android:scheme="reversal_response" />
</intent-filter>

Init

Init cielo_lio_helper by providing the host and schemes from the previous step:

CieloLioHelper.init(
    host: "dev.mauricifj",
    schemes: SchemeAggregate(
        printResponseScheme: "print_response",
        paymentResponseScheme: "payment_response",
        reversalResponseScheme: "reversal_response",
    ),
);

Using

The easiest way to use this library is via the top-level functions. They allow you to use InfoManager and OrderManager with minimal hassle:

Retrieving EC Example

String ec;
try {
    ec = await CieloLioHelper.ec;
} on PlatformException {
    ec = 'Failed to get ec.';
}

Retrieving Logic Number Example

String logicNumber;
try {
    logicNumber = await CieloLioHelper.logicNumber;
} on PlatformException {
    logicNumber = 'Failed to get logic number.';
}

Retrieving Battery Level Example

double batteryLevel;
try {
    batteryLevel = await CieloLioHelper.batteryLevel;
} on PlatformException {
    batteryLevel = -1;
}

Checkout Example

var random = Random();
var unitPrice = random.nextInt(400) + 100;
var quantity = random.nextInt(9) + 1;
var total = unitPrice * quantity;

var request = CheckoutRequest(
    clientID: "YOUR-CLIENT-ID",
    accessToken: "YOUR-ACCESS-TOKEN",
    value: total,
    paymentCode: "CREDITO_AVISTA",
    installments: 0,
    email: "[email protected]",
    merchantCode: "0000000000000003",
    reference: "reference_text",
    items: List.from(
    [
        Item(
            sku: "${Random().nextInt(100000) + 1000}",
            name: "water bottle",
            unitPrice: unitPrice,
            quantity: quantity,
            unitOfMeasure: "bottle",
        ),
    ],
    ),
);

CieloLioHelper.checkout(request, (response) {
    print(response.id);
});

Cancellation Example

var request = CancelRequest(
    clientID: "YOUR-CLIENT-ID",
    accessToken: "YOUR-ACCESS-TOKEN",
    value: paymentResponse.payments[0].amount,
    authCode: paymentResponse.payments[0].authCode,
    cieloCode: paymentResponse.payments[0].cieloCode,
    merchantCode: paymentResponse.payments[0].merchantCode,
    id: paymentResponse.id,
);

CieloLioHelper.cancelPayment(request, (response) {
    print(response.id);
});

Print Example

CieloLioHelper.enqueue("SAMPLE TEXT", PrintAlignment.LEFT, 30, 1);
CieloLioHelper.enqueue("SAMPLE TEXT", PrintAlignment.CENTER, 20, 2);
CieloLioHelper.enqueue("SAMPLE TEXT\n\n\n", PrintAlignment.RIGHT, 10, 2);

CieloLioHelper.printQueue((LioResponse response) {
    print(response.code);
    print(response.message);
});
