Getting Started #

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_txms: ^0.1.0

Usage #

Basic Example #

import 'package:flutter_txms/flutter_txms.dart';

void main() {
  final txms = Txms();

  // Encode a hex string
  final encoded = txms.encode('0x48656c6c6f20576f726c64'); // "Hello World"
  print('Encoded: $encoded');

  // Decode back to hex
  final decoded = txms.decode(encoded);
  print('Decoded: $decoded');
}

SMS Generation and Opening #

final txms = Txms();

// Generate SMS URI
final smsUri = txms.sms(
  number: '+12019715152',
  message: '0x48656c6c6f',
  network: 'mainnet',
);
print('SMS URI: $smsUri');

// Open SMS client directly with encoded message
await txms.openSmsClient(
  number: '+12019715152',
  message: '0x48656c6c6f',
  network: 'mainnet',
);

// Open MMS client directly with encoded message
await txms.openMmsClient(
  number: '+12019715152',
  message: '0x48656c6c6f',
  network: 'mainnet',
);

File Operations #

final txms = Txms();

// Save message to file
final filePath = await txms.downloadMessage(
  '0x48656c6c6f20576f726c64',
  optionalFilename: 'hello',
);
print('Saved to: $filePath');

Message Counting #

final txms = Txms();

// Count SMS segments
final smsCount = txms.count('0x48656c6c6f20576f726c64', 'sms');
print('Number of SMS segments: $smsCount');

// Count MMS segments
final mmsCount = txms.count('0x48656c6c6f20576f726c64', 'mms');
print('Number of MMS segments: $mmsCount');
