Getting Started

How to use

This plugin exposes two APIs:

1. Initialize

Initialize the plugin. This should be done once.

import 'package:flutteremv/flutteremv.dart';

class _MyAppState extends State<MyApp> {
final _flutteremvPlugin = Flutteremv();

  @override
  void initState() {
    _flutteremvPlugin.initialize("masterKey", "pinkey");
    super.initState();
  }
}

2. Initialize Payment

Create an object of the Transaction class and pass it to the initializePayment function

Future<void> initPayment() async {
    _flutteremvPlugin.debitcard("2000");
}

3. Listen to card state

listening to card event to know the state of your card you can do whatever you like with the state

 _flutteremvPlugin.stateStream.listen((values)  async {
      print(" card state $values");
      // Handle the state change here
      switch (values["state"]) {
        case "Loading":
          showDialog(context: context, builder: (builder)=> AlertDialog(title: Text("Loading"),));
          return ;
        case "CardData":
          eventresult = values;
          return ;
        case "CardReadTimeOut":
          return ;
        case "CallBackError":
          return ;
        case "CallBackCanceled":
          return ;
        case "CallBackTransResult":
          return ;
        case "CardDetected":
          var result = await Navigator.push(
            context,
            MaterialPageRoute(builder: (context) => Carpin(amount: "200",)),
          );
          if(result != null){
            _flutteremvPlugin.enterpin(result);
          }
          return ;

      }
    });

4. customise card pin layout

send pin entered back to the sdk card wait for response from the event you listen to earlier

 _flutteremvPlugin.enterpin(result);

4. Withdraw receipt printing

                  _topwisePlugin.startprinting(args).then((value) {print(value);});

7. Customise printing

when creating your ui for customise printing in consider the following

1. You can't use more than two widget in a row

2. The sdk understand limited Widget which are Column, Row, container, Expanded, Text, Image, Divider

3. if you are printing a list in the Ui, do not use ListView, you can use for loop

4. Any widget used differently from the above listed, sdk will interpret it has space

The TransactionMonitor class received after sdk is closed contains the below fields

String state;
String message;
bool status;
DebitCardRequestDto? transactionData;
