在将 razorpay 与颤振集成时出现此错误。我是否正确编写了代码。

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

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

@override
void dispose() {
super.dispose();
_razorpay.clear();
}

 void openCheckout() async {
 var options = {
  'key': 'rzp_test_geinuADCB6Csdb',
  'amount': 10*100,
  'name': 'BidAnd2Win',
  'description': 'Buying Bid to play game',
  'prefill': {'contact': '8888888888', 'email': 'test@razorpay.com'},
  'external': {
    'wallets' : ['paytm'],
  }
 };
try{
 _razorpay.open(options);
}
catch(e) {
  debugPrint(e);
}

}

void _handlePaymentSuccess(PaymentSuccessResponse response) {
  Fluttertoast.showToast(msg: 'Success' + response.paymentId);
}

void _handlePaymentError(PaymentFailureResponse response) {
  Fluttertoast.showToast(msg: 'Failure' + response.code.toString() + " - " + response.message);
}

void _handleExternalWallet(ExternalWalletResponse response) {
  Fluttertoast.showToast(msg: 'Sucess Wallet payment' + response.walletName);
}

起初，当为所有这三种方法调用 initState() 时出现错误 [错误：flutter/lib/ui/ui_dart_state.cc(157)] 未处理的异常：MissingPluginException（未找到通道 razorpay_flutter 上打开的方法的实现）

然后是第二种方法

[错误：flutter/lib/ui/ui_dart_state.cc(157)] 未处理的异常：MissingPluginException（未找到通道 razorpay_flutter 上的方法重新同步的实现）

对于第三种方法

[错误：flutter/lib/ui/ui_dart_state.cc(157)] 未处理的异常：MissingPluginException（未找到通道 razorpay_flutter 上的方法重新同步的实现）

我还正确添加了我的 razorpay_flutter，但是当我单击按钮并调用方法 openCheckout() 时，会发生 missingPluginException。如何修复这个未处理的异常错误，我已经在 try 和 catch 块中调用了 _razorpay.open(options)

解决方案

颤抖干净，然后重新启动，然后就可以了
