我是
Dartflutter我想用波斯语号码替换英语号码。 如何实现这一点？
1-2-3-4-5-6-7-8-9 ==> ۱-۲-۳-۴-۵-۶-۷-۸-۹
示例：
String replaceFarsiNumber(String input) {
const english = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];
const farsi = ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'];
for (int i = 0; i < english.length; i++) {
input = input.replaceAll(english[i], farsi[i]);
}
return input;
}
main() {
print(replaceFarsiNumber('0-1-2-3-4-5-6-7-8-9')); // ==> ۰-۱-۲-۳-۴-۵-۶-۷-۸-۹
}
static String ConvertDigitsToLatin(String s) {
var sb = new StringBuffer();
for (int i = 0; i < s.length; i++) {
switch (s[i]) {
//Persian digits
case '\u06f0':
sb.write('0');
break;
case '\u06f1':
sb.write('1');
break;
case '\u06f2':
sb.write('2');
break;
case '\u06f3':
sb.write('3');
break;
case '\u06f4':
sb.write('4');
break;
case '\u06f5':
sb.write('5');
break;
case '\u06f6':
sb.write('6');
break;
case '\u06f7':
sb.write('7');
break;
case '\u06f8':
sb.write('8');
break;
case '\u06f9':
sb.write('9');
break;
//Arabic digits
case '\u0660':
sb.write('0');
break;
case '\u0661':
sb.write('1');
break;
case '\u0662':
sb.write('2');
break;
case '\u0663':
sb.write('3');
break;
case '\u0664':
sb.write('4');
break;
case '\u0665':
sb.write('5');
break;
case '\u0666':
sb.write('6');
break;
case '\u0667':
sb.write('7');
break;
case '\u0668':
sb.write('8');
break;
case '\u0669':
sb.write('9');
break;
default:
sb.write(s[i]);
break;
}
}
return sb.toString();
}
不确定您将在什么情况下使用这些数字，但我宁愿定义一个 const 映射：
const numberMap = {0: '۰', 1: '۱', 2:'۲', 3:'۳', 4:'٤', 5:'۵', 6:'٦', 7:'۷', 8:'۸',9: '۹'};numberMap[number]取决于这个答案：https://stackoverflow.com/a/63934087/14409491
extension NumberConverter on num {
static const Map<String, String> arabicDigits = <String, String>{
'0': '\u0660',
'1': '\u0661',
'2': '\u0662',
'3': '\u0663',
'4': '\u0664',
'5': '\u0665',
'6': '\u0666',
'7': '\u0667',
'8': '\u0668',
'9': '\u0669',
};
String toArabicDigits() {
final String number = toString();
StringBuffer sb = StringBuffer();
for (int i = 0; i < number.length; i++) {
sb.write(arabicDigits[number[i]] ?? number[i]);
}
return sb.toString();
}
}
这是我的解决方案：
String engNumberToFarsi(String number) {
Map numbers = {
'0' : '۰',
'1' : '۱',
'2' : '۲',
'3' : '۳',
'4' : '۴',
'5' : '۵',
'6' : '۶',
'7' : '۷',
'8' : '۸',
'9' : '۹',
};
numbers.forEach((key, value) => number = number.replaceAll(key, value));
return number;
}
我参加聚会有点晚了，但这里有一个使用
RegExpString.replaceAllMapped(...)extension ToFarsiNumber on String {
String toFarsi() {
const Map<String, String> numbers = {
'0': '۰',
'1': '۱',
'2': '۲',
'3': '۳',
'4': '۴',
'5': '۵',
'6': '۶',
'7': '۷',
'8': '۸',
'9': '۹',
};
return replaceAllMapped(
RegExp('[0-9]'),
(match) => numbers[this[match.start]]!,
);
}
}
用途：
'0-1-2-3-4-5-6-7-8-9'.toFarsi(); // ۰-۱-۲-۳-۴-۵-۶-۷-۸-۹

String replaceFarsiNumber(String input) {
const english = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];
const farsi = ['۰', '۱', '۲', '۳', '۴', '۵', '٦', '۷', '۸', '۹'];
for (int i = 0; i < english.length; i++) {
input = input.replaceAll(english[i], farsi[i]);
}
return input;
}
}@Xavier 答案是正确的，但是我建议定义一个扩展来使用，而不是每次都用函数包装字符串
extension FarsiNumberExtension on String {
String get farsiNumber {
const english = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];
const farsi = ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'];
String text = this;
for (int i = 0; i < english.length; i++) {
text = text.replaceAll(english[i], farsi[i]);
}
return text;
}
}
然后像这样使用
print('0-1-2-3-4-5-6-7-8-9'.farsiNumber);
print('myNumber123'.farsiNumber);
输出
۰-۱-۲-۳-۴-۵-۶-۷-۸-۹

localizeDigits()hrk_batteries添加包：
$ dart pub add hrk_batteries
使用方法如下：
import 'package:hrk_batteries/hrk_batteries.dart';
void main() {
final String enToArLocalizedString = 'A0123456789Z'.localizeDigits(
toZeroDigit: '\u0660', // toZeroDigit: '٠',
);
print(enToArLocalizedString); // A٠١٢٣٤٥٦٧٨٩Z
final String enToFaLocalizedString = 'A0123456789Z'.localizeDigits(
toZeroDigit: '\u06f0', // toZeroDigit: '۰',
);
print(enToFaLocalizedString); // A۰۱۲۳۴۵۶۷۸۹Z
}
