One-time Payment Request

InitRequest req = new InitRequest();
//Required Params
req.setMerchantId("1210XXX");       // Your Merchant PayHere ID
req.setMerchantSecret("ugknesnvn"); // Your Merchant secret (Add your app at Settings > Domains & Credentials, to get this))
req.setCurrency("LKR");             // Currency code LKR/USD/GBP/EUR/AUD
req.setAmount(1000.00);             // Final Amount to be charged
req.setOrderId("230000123");        // Unique Reference ID
req.setItemsDescription("Door bell wireless");  // Item description title 
req.setCustom1("This is the custom message 1");
req.setCustom2("This is the custom message 2");
req.getCustomer().setFirstName("Saman");
req.getCustomer().setLastName("Perera");
req.getCustomer().setEmail("[email protected]");
req.getCustomer().setPhone("+94771234567");
req.getCustomer().getAddress().setAddress("No.1, Galle Road");
req.getCustomer().getAddress().setCity("Colombo");
req.getCustomer().getAddress().setCountry("Sri Lanka");

//Optional Params
req.getCustomer().getDeliveryAddress().setAddress("No.2, Kandy Road");
req.getCustomer().getDeliveryAddress().setCity("Kadawatha");
req.getCustomer().getDeliveryAddress().setCountry("Sri Lanka");
req.getItems().add(new Item(null, "Door bell wireless", 1, 1000.0));

call SANDBOX or LIVE end points with InitRequest

RaisedButton(  
  onPressed: () async {  
  // SANDBOX 
    PhResponse response =  
        await PayhereFlutter.oneTimePaymentSandbox(request: req);  
  child: Text("One Time Payment SANDBOX"),

🚀 Release

flutter uses R8 code shrinker by default if you want to use R8 you need to add proguard-rules.pro to your flutter app. more

1. release with R8 ( default)

   i. create proguard-rules.pro under android>app and add this

   -keep class lk.payhere.** { *; }
   

   ii. under app>build.gradle add this

buildTypes {  
  release {  
  // TODO: Add your own signing config for the release build.  
  // Signing with the debug keys for now, so `flutter run --release` works.  
  
  minifyEnabled true  
  useProguard true  
  proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'  
  signingConfig signingConfigs.debug  
    }  
}

2. without code shrinking

   run flutter build apk --no-shrink
