Razorpay在付款页面上崩溃

flutter run在仿真器和真实设备中运行正常。 但在flutter build apk之后，该应用在_razorpay.open(options);上崩溃了 并且该插件未在Visual Studio代码终端中显示崩溃报告或任何错误。

  final _razorpay = Razorpay();
 _razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS,_handlePaymentSuccess);
  _razorpay.on(Razorpay.EVENT_PAYMENT_ERROR,_handlePaymentError);
 _razorpay.on(Razorpay.EVENT_EXTERNAL_WALLET,_handleExternalWallet);

  var options = {
      'key': 'rzp_test_xxxxxxx','amount': 100,//in the smallest currency sub-unit.
      'name': 'Acme Corp.','description': 'Fine T-Shirt','prefill': {'contact': '9123456789','email': 'test.kumar@example.com'}
    };

    print('0');
 try {
      print('1');
      _razorpay.open(options);
      print('2');
    } catch (e) {
      print('error');
      debugPrint(e);
    }

在Visual Studio代码终端中

11-05 00:22:29.197 21170 21209 I flutter : 0
11-05 00:22:29.197 21170 21209 I flutter : 1
11-05 00:22:29.197 21170 21209 I flutter : 2

在Andoid Studio Logcat中

java.lang.ClassnotFoundException：找不到类“ com.razorpay.d__1 _”

我只是按照以下步骤进行操作。

1步
在 android> app
中创建 proguard-rules.pro 文件名 应该是： android / app / proguard-rules.pro
在 proguard-rules 文件中添加以下行

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

-keepattributes JavascriptInterface
-keepattributes *Annotation*

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

-optimizations !method/inlining/*

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

2步
转到android> app> build.gradle并找到 buildTypes
在buildTypes> release内部添加一些行

buildTypes {
        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'
        }
    }

现在Razorpay正在运行。

我遇到了同样的问题，尝试了几天，最后我换到了 razorpay 1.6.11 的最新版本（2021 年 8 月 11 日），尝试不同的版本，它会工作
