convertToArabicWords function

String convertToArabicWords(int number)

Converts an integer into Arabic words. Supports numbers from 0 to 9999.

Example:

logFile(key: convertToArabicWords(1234), name: 'convert to arabic words'); // "ألف ومائتان وأربعة وثلاثون"
logFile(key: convertToArabicWords(15), name: 'convert to arabic words');   // "خمسة عشر"
logFile(key: convertToArabicWords(1000), name: 'convert to arabic words'); // "ألف"
