Morse Code Converter Package

A simple and efficient Dart package for converting between English text and Morse code. This package provides utilities to encode text to Morse code and decode Morse code back to text, with support for punctuation and enhanced error handling.

Features

• Text to Morse Conversion: Convert English text (including spaces and punctuation) to Morse code.
• Morse to Text Conversion: Decode valid Morse code sequences to readable English text.
• Punctuation Support: Supports common punctuation characters like . , ? !.
• Error Handling: Alerts when encountering unsupported characters or invalid Morse sequences.
• Validation Functions:
  • isValidText() ensures input contains only convertible characters.
  • isValidMorse() checks if Morse input follows valid patterns.

Installation

Add the following to your pubspec.yaml file:

dependencies:
  morse_code_converter: ^1.0.0

Then, run:

flutter pub get

Usage

Import the Package

import 'package:morse_code_converter/morse_code_converter.dart';

Encode Text to Morse

void main() {
  String text = "HELLO, WORLD!";
  String morseCode = textToMorse(text);
  print("Morse Code: $morseCode");
}

Decode Morse to Text

void main() {
  String morseCode = ".... . .-.. .-.. --- / .-- --- .-. .-.. -..";
  String decodedText = morseToText(morseCode);
  print("Decoded Text: $decodedText");
}

Validation Example

void main() {
  String text = "HELLO!";
  if (isValidText(text)) {
    print("Valid for Morse Conversion");
  } else {
    print("Invalid characters in text.");
  }
}
