谁能告诉我如何在 flutter 中解析这个 JSON。我被困住了，我成功创建了类，但从解析方法中收到错误这是 JSON

{
    "btcinr": {
        "base_unit": "btc",
        "quote_unit": "inr",
        "low": "3001337.0",
        "high": "3145000.0",
        "last": "3107312.0",
        "type": "SPOT",
        "open": "3085453",
        "volume": "243.1121",
        "sell": "3114335.0",
        "buy": "3106628.0",
        "at": 1646663606,
        "name": "BTC/INR"
    }
}

我被困住并出错的方法是

Future<List<Map<String, dynamic>>> fetchData() async {
    final response =
        await http.get(Uri.parse("https://api.wazirx.com/api/v2/tickers"));
    if (response.statusCode == 200) {
      final responseJson = json.decode(response.body);
      
    } else {
      throw Exception('Unexpected Error Occured!');
    }
  }

此方法不完整，任何帮助将不胜感激，谢谢！
