    //     toastLength: Toast.LENGTH_SHORT);
  }

  void _handlePaymentError(PaymentFailureResponse response) {
    print("${response.code.toString() + " - " + response.message!}");

    // Fluttertoast.showToast(
    //     msg: "ERROR: " + response.code.toString() + " - " + response.message!,
    //     toastLength: Toast.LENGTH_SHORT);
  }

  void _handleExternalWallet(ExternalWalletResponse response) {
    print("${"EXTERNAL_WALLET: " + response.walletName!}");

    // Fluttertoast.showToast(
    //     msg: "EXTERNAL_WALLET: " + response.walletName!,
    //     toastLength: Toast.LENGTH_SHORT);
  }

So this is my code all went perfect in debug mode but failed in release mode

I got an solution from razorPay team and they said i have miss placed proguard rules file and they said to place on app folder Now my proguard rules file look like this proguard-rules.pro

-keepclassmembers class * {
    @android.webkit.JavascriptInterface ;
}

-keepattributes JavascriptInterface
-keepattributes *Annotation*

-dontwarn com.razorpay.**
-keep class com.razorpay.** {*;}

-optimizations !method/inlining/*

-keepclasseswithmembers class * {
  public void onPayment*(...);
}

in app/build.gradle

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