⚠️ Potential issue

Add a null or empty-check for rawTx.contract to prevent runtime errors.

If rawTx.contract is empty, calling rawTx.contract.first will cause an out-of-range error. Consider adding a guard clause before accessing .first.

Proposed fix:

 if (json
     case {
       "txID": String hash,
       "net_usage": int _,
       "net_fee": int netFee,
       "energy_usage": int _,
       "energy_fee": int energyFee,
       "blockNumber": int block,
       "block_timestamp": int block_timestamp,
       "raw_data_hex": String raw_data_hex,
     }) {
   final fee = Amount(
     value: BigInt.from(netFee + energyFee),
     decimals: 6,
   );

   final rawData = raw_data_hex.hexToBytes;
+  // Guard check for empty contract list
+  if (rawData.isEmpty) {
+    return null; // or handle appropriately
+  }
 
-  final Transaction_raw rawTx = Transaction_raw.fromBuffer(rawData);
+  final rawTx = Transaction_raw.fromBuffer(rawData);
+  if (rawTx.contract.isEmpty) {
+    return null; // or handle appropriately
+  }
   final contract = rawTx.contract.first;
   ...
 }

final contract = rawTx.contract.first;
final contractType = contract.type;
