easymerchantsdk 0.0.1

EasyMerchantSDK

Easy Merchant Sdk Implementation.

To implement the sdk in your flutter project, you have to add the below path in your pubspec.yaml file inside dependencies section:

dependencies:
  easymerchantsdk:
    git: git_url
    ref: ref

Easy Merchant Sdk Implementation(Android Side).

Follow the below steps to implement the easymerchant sdk in your flutter project

Change the minimum sdk version.

In your android -> app -> build.gradle file, there is a defaultConfig section. Change the minSdk to 24 in the defaultConfig.

Add the dependencies.

Add the below dependencies in your android -> app -> build.gradle file.

dependencies {
    implementation 'com.app:paysdk:1.1.9'
    implementation 'com.hbb20:ccp:2.7.3'
    implementation 'com.github.androidmads:QRGenerator:1.0.1'
    implementation 'com.google.android.material:material:1.12.0'
    implementation 'androidx.appcompat:appcompat:1.6.1'
}

Add the gradle urls.

To add the gradle urls, open your android -> build.gradle file and add the below lines in it.

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
        maven {
            url = uri(your_github_url)
            credentials {
                username = username
                password = password
            }
        }
    }

    configurations.all {
        resolutionStrategy {
            force 'org.jetbrains.kotlin:kotlin-stdlib:1.8.22' // Replace with your desired version
        }
    }
}

Changes in settings.gradle file.

Now open your android -> settings.gradle and add the below code inside repositories block.

repositories {
        ...
        maven { url 'https://jitpack.io' }
        maven {
            url = uri(your_github_url)
            credentials {
                username = username
                password = password
            }
        }
    }

Changes in MainActivity file

Inside your andorid/app/src/main/kotlin/your_package_name There is MainActivity.kt file, replace all code except first line with below:

import android.os.Bundle
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.MethodChannel
import com.example.easymerchantsdk.EasymerchantsdkPlugin


class MainActivity: FlutterActivity(){
    private val CHANNEL = "easymerchantsdk"
    private var easymerchantsdkPlugin: EasymerchantsdkPlugin? = null
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        easymerchantsdkPlugin = EasymerchantsdkPlugin()
        easymerchantsdkPlugin?.setActivity(this)
    }
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
//        EasymerchantsdkPlugin.registerWith(flutterEngine.dartExecutor.binaryMessenger)
        super.configureFlutterEngine(flutterEngine)
        //  GeneratedPluginRegistrant.registerWith(flutterEngine)
        easymerchantsdkPlugin?.let {
            EasymerchantsdkPlugin().setActivity(this)
        }

        MethodChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setMethodCallHandler { call, result ->
            if (call.method == "billing") {
                val amount = call.argument<String>("amount") ?: ""
                val billinginfo = call.argument<String?>("billinginfo") ?: ""


                easymerchantsdkPlugin?.onMethodCall(call, result)
            } else if(call.method == "getPlatformVersion"){
                result.success("Android ${android.os.Build.VERSION.RELEASE}")
            } else {
                result.notImplemented()
            }
        }
    }
}

How to call the sdk.

Now, to call the sdk, please check the below exmaple code of dart file.

import 'dart:convert';
import 'dart:io';

import 'package:easymerchantsdk/easymerchantsdk.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

  @override
  void initState() {
    super.initState();

    WidgetsBinding.instance.addPostFrameCallback((_) {
      initPlatformState();
      if (Platform.isIOS) {

  }

  Future<void> initPlatformState() async {
    try {

    } catch (e) {
      showSnackbar('Failed to get platform version: $e');
    }
  }

  Future<void> initializeViewController() async {
    try {

      String jsonRequestt = jsonEncode(jsonRequest);

      final result = await easymerchant.makePayment(
