阿拉伯语译成英语

String replaceArabicNumber(String input) {
    const english = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];
    const arabic = ['٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩'];

    for (int i = 0; i < english.length; i++) {
      input = input.replaceAll(arabic[i], english[i]);
    }
    print("$input");
    return input;
  }

相反，用阿拉伯数字替换英语数字（English to Arabic）

String replaceEnglishNumber(String input) {
    const english = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];
    const arabic = ['٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩'];

    for (int i = 0; i < english.length; i++) {
      input = input.replaceAll(english[i], arabic[i]);
    }
    print("$input");
    return input;
  }
