⚠️ Potential issue

Add necessary wallet-related imports and error handling.

As this is a wallet interface implementation, the file should import the necessary wallet-related modules and implement proper error handling for I/O operations.

Consider adding:

 import 'dart:io';
+import 'package:walletkit_dart/walletkit_dart.dart';
+import 'dart:async';
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🛠️ Refactor suggestion

Enhance main function with wallet initialization and CLI argument handling.

The current implementation lacks essential wallet functionality initialization and doesn't utilize the command-line arguments.

Consider implementing:

  1. Command-line argument parsing for wallet operations
  2. Wallet initialization
  3. Usage instructions
  4. Error handling

Example structure:

void main(List<String> args) async {
  try {
    if (args.contains('--help')) {
      printUsage();
      return;
    }
    
    print("Welcome to Walletkit-Dart");
    final wallet = await WalletKit.initialize();
    
    // Interactive loop here
    
  } catch (e) {
    print("Error: $e");
    exit(1);
  }
}

while (true) {
final input = stdin.readLineSync();

if (input == 'exit') {
break;
}
}

🛠️ Refactor suggestion

Implement proper command processing and async I/O.

The current interactive loop implementation has several limitations:

  1. Uses blocking I/O
  2. Lacks command processing
  3. No error handling
  4. No user feedback

Consider implementing:

while (true) {
  stdout.write('wallet> ');
  String? input;
  try {
    input = await stdin.readLineSync();
    if (input == null) continue;
    
    if (input == 'exit') {
      break;
    }
    
    final result = await processCommand(input);
    print(result);
  } catch (e) {
    print('Error: $e');
  }
}

Future<String> processCommand(String input) async {
  final parts = input.split(' ');
  switch (parts[0]) {
    case 'balance':
      return await wallet.getBalance();
    case 'send':
      if (parts.length != 3) return 'Usage: send <address> <amount>';
      return await wallet.send(parts[1], double.parse(parts[2]));
    case 'help':
      return '''
Available commands:
  balance - Show wallet balance
  send <address> <amount> - Send funds
  exit - Exit the application
''';
    default:
      return 'Unknown command. Type "help" for available commands.';
  }
}
